## Description

While complete access to the layout capabilities of Pango is provided using the detailed interfaces for itemization and shaping, using that functionality directly involves writing a fairly large amount of code. The objects and functions in this section provide a high-level driver for formatting entire paragraphs of text at once.

## Functions

### pango_layout_new ()

    PangoLayout *
    pango_layout_new (PangoContext *context);

Create a new PangoLayout object with attributes initialized to default values for a particular PangoContext.

#### Parameters

context | a PangoContext |

#### Returns

the newly allocated PangoLayout, with a reference count of one, which should be freed with `g_object_unref()`.

### pango_layout_copy ()

    PangoLayout *
    pango_layout_copy (PangoLayout *src);

Does a deep copy-by-value of the `src` layout. The attribute list, tab array, and text from the original layout are all copied by value.

#### Parameters

src | a PangoLayout |

#### Returns

the newly allocated PangoLayout, with a reference count of one, which should be freed with `g_object_unref()`.

[transfer full]

### pango_layout_get_context ()

    PangoContext *
    pango_layout_get_context (PangoLayout *layout);

Retrieves the PangoContext used for this layout.

#### Parameters

layout | a PangoLayout |

#### Returns

the PangoContext for the layout. This does not have an additional refcount added, so if you want to keep a copy of this around, you must reference it yourself.

[transfer none]

### pango_layout_context_changed ()

    void
    pango_layout_context_changed (PangoLayout *layout);

Forces recomputation of any state in the PangoLayout that might depend on the layout's context. This function should be called if you make changes to the context subsequent to creating the layout.

#### Parameters

layout | a PangoLayout |

### pango_layout_get_serial ()

    guint
    pango_layout_get_serial (PangoLayout *layout);

Returns the current serial number of `layout` . The serial number is initialized to an small number larger than zero when a new layout is created and is increased whenever the layout is changed using any of the setter functions, or the PangoContext it uses has changed. The serial may wrap, but will never have the value 0. Since it can wrap, never compare it with "less than", always use "not equals".

This can be used to automatically detect changes to a PangoLayout, and is useful for example to decide whether a layout needs redrawing. To force the serial to be increased, use `pango_layout_context_changed()`.

#### Parameters

layout | a PangoLayout |

#### Returns

The current serial number of `layout` .

Since: 1.32.4

### pango_layout_set_text ()

    void
    pango_layout_set_text (PangoLayout *layout,
                           const char *text,
                           int length);

Sets the text of the layout.

Note that if you have used `pango_layout_set_markup()` or `pango_layout_set_markup_with_accel()` on `layout` before, you may want to call `pango_layout_set_attributes()` to clear the attributes set on the layout from the markup as this function does not clear attributes.

#### Parameters

layout | a PangoLayout |
text | a valid UTF-8 string |
length | maximum length of `text` , in bytes. -1 indicates that the string is nul-terminated and the length should be calculated. The text will also be truncated on encountering a nul-termination even when `length` is positive. |

### pango_layout_get_text ()

    const char *
    pango_layout_get_text (PangoLayout *layout);

Gets the text in the layout. The returned text should not be freed or modified.

#### Parameters

layout | a PangoLayout |

#### Returns

the text in the `layout` .

### pango_layout_get_character_count ()

    gint
    pango_layout_get_character_count (PangoLayout *layout);

Returns the number of Unicode characters in the the text of `layout` .

#### Parameters

layout | a PangoLayout |

#### Returns

the number of Unicode characters in the text of `layout`

Since: 1.30

### pango_layout_set_markup ()

    void
    pango_layout_set_markup (PangoLayout *layout,
                             const char *markup,
                             int length);

Same as `pango_layout_set_markup_with_accel()`, but the markup text isn't scanned for accelerators.

#### Parameters

layout | a PangoLayout |
markup | marked-up text |
length | length of marked-up text in bytes, or -1 if `markup` is null-terminated |

### pango_layout_set_markup_with_accel ()

    void
    pango_layout_set_markup_with_accel (PangoLayout *layout,
                                        const char *markup,
                                        int length,
                                        gunichar accel_marker,
                                        gunichar *accel_char);

Sets the layout text and attribute list from marked-up text (see

markup format). Replaces

the current text and attribute list.

If `accel_marker` is nonzero, the given character will mark the character following it as an accelerator. For example, `accel_marker` might be an ampersand or underscore. All characters marked as an accelerator will receive a `PANGO_UNDERLINE_LOW` attribute, and the first character so marked will be returned in `accel_char` . Two `accel_marker` characters following each other produce a single literal `accel_marker` character.

#### Parameters

layout | a PangoLayout |
markup | marked-up text (see markup format) |
length | length of marked-up text in bytes, or -1 if `markup` is null-terminated |
accel_marker | marker for accelerators in the text |
accel_char | return location for first located accelerator, or `NULL`. | [out caller-allocates][allow-none]

### pango_layout_set_attributes ()

    void
    pango_layout_set_attributes (PangoLayout *layout,
                                 PangoAttrList *attrs);

Sets the text attributes for a layout object. References `attrs` , so the caller can unref its reference.

#### Parameters

layout | a PangoLayout |
attrs | a PangoAttrList, can be `NULL`. | [allow-none][transfer none]

### pango_layout_get_attributes ()

    PangoAttrList *
    pango_layout_get_attributes (PangoLayout *layout);

Gets the attribute list for the layout, if any.

#### Parameters

layout | a PangoLayout |

#### Returns

a PangoAttrList.

[transfer none]

### pango_layout_set_font_description ()

    void
    pango_layout_set_font_description (PangoLayout *layout,
                                       const PangoFontDescription *desc);

Sets the default font description for the layout. If no font description is set on the layout, the font description from the layout's context is used.

#### Parameters

layout | a PangoLayout |
desc | the new PangoFontDescription, or `NULL` to unset the current font description. | [allow-none]

### pango_layout_get_font_description ()

    const PangoFontDescription *
    pango_layout_get_font_description (PangoLayout *layout);

Gets the font description for the layout, if any.

#### Parameters

layout | a PangoLayout |

#### Returns

a pointer to the layout's font description, or `NULL` if the font description from the layout's context is inherited. This value is owned by the layout and must not be modified or freed.

[nullable]

Since: 1.8

### pango_layout_set_width ()

    void
    pango_layout_set_width (PangoLayout *layout,
                            int width);

Sets the width to which the lines of the PangoLayout should wrap or ellipsized. The default value is -1: no width set.

#### Parameters

layout | a PangoLayout. |
width | the desired width in Pango units, or -1 to indicate that no wrapping or ellipsization should be performed. |

### pango_layout_get_width ()

    int
    pango_layout_get_width (PangoLayout *layout);

Gets the width to which the lines of the PangoLayout should wrap.

#### Parameters

layout | a PangoLayout |

#### Returns

the width in Pango units, or -1 if no width set.

### pango_layout_set_height ()

    void
    pango_layout_set_height (PangoLayout *layout,
                             int height);

Sets the height to which the PangoLayout should be ellipsized at. There are two different behaviors, based on whether `height` is positive or negative.

If `height` is positive, it will be the maximum height of the layout. Only lines would be shown that would fit, and if there is any text omitted, an ellipsis added. At least one line is included in each paragraph regardless of how small the height value is. A value of zero will render exactly one line for the entire layout.

If `height` is negative, it will be the (negative of) maximum number of lines per paragraph. That is, the total number of lines shown may well be more than this value if the layout contains multiple paragraphs of text. The default value of -1 means that first line of each paragraph is ellipsized. This behvaior may be changed in the future to act per layout instead of per paragraph. File a bug against pango at http://bugzilla.gnome.org/ if your code relies on this behavior.

Height setting only has effect if a positive width is set on `layout` and ellipsization mode of `layout` is not `PANGO_ELLIPSIZE_NONE`. The behavior is undefined if a height other than -1 is set and ellipsization mode is set to `PANGO_ELLIPSIZE_NONE`, and may change in the future.

#### Parameters

layout | a PangoLayout. |
height | the desired height of the layout in Pango units if positive, or desired number of lines if negative. |

Since: 1.20

### pango_layout_get_height ()

    int
    pango_layout_get_height (PangoLayout *layout);

Gets the height of layout used for ellipsization. See `pango_layout_set_height()` for details.

#### Parameters

layout | a PangoLayout |

#### Returns

the height, in Pango units if positive, or number of lines if negative.

Since: 1.20

### pango_layout_set_wrap ()

    void
    pango_layout_set_wrap (PangoLayout *layout,
                           PangoWrapMode wrap);

Sets the wrap mode; the wrap mode only has effect if a width is set on the layout with `pango_layout_set_width()`. To turn off wrapping, set the width to -1.

#### Parameters

layout | a PangoLayout |
wrap | the wrap mode |

### pango_layout_get_wrap ()

    PangoWrapMode
    pango_layout_get_wrap (PangoLayout *layout);

Gets the wrap mode for the layout.

Use `pango_layout_is_wrapped()` to query whether any paragraphs were actually wrapped.

#### Parameters

layout | a PangoLayout |

#### Returns

active wrap mode.

### pango_layout_is_wrapped ()

    gboolean
    pango_layout_is_wrapped (PangoLayout *layout);

Queries whether the layout had to wrap any paragraphs.

This returns `TRUE` if a positive width is set on `layout` , ellipsization mode of `layout` is set to `PANGO_ELLIPSIZE_NONE`, and there are paragraphs exceeding the layout width that have to be wrapped.

#### Parameters

layout | a PangoLayout |

#### Returns

`TRUE` if any paragraphs had to be wrapped, `FALSE` otherwise.

Since: 1.16

### pango_layout_set_ellipsize ()

    void
    pango_layout_set_ellipsize (PangoLayout *layout,
                                PangoEllipsizeMode ellipsize);

Sets the type of ellipsization being performed for `layout` . Depending on the ellipsization mode `ellipsize` text is removed from the start, middle, or end of text so they fit within the width and height of layout set with `pango_layout_set_width()` and `pango_layout_set_height()`.

If the layout contains characters such as newlines that force it to be layed out in multiple paragraphs, then whether each paragraph is ellipsized separately or the entire layout is ellipsized as a whole depends on the set height of the layout. See `pango_layout_set_height()` for details.

#### Parameters

layout | a PangoLayout |
ellipsize | the new ellipsization mode for `layout` |

Since: 1.6

### pango_layout_get_ellipsize ()

    PangoEllipsizeMode
    pango_layout_get_ellipsize (PangoLayout *layout);

Gets the type of ellipsization being performed for `layout` . See `pango_layout_set_ellipsize()`

#### Parameters

layout | a PangoLayout |

#### Returns

the current ellipsization mode for `layout` .

Use `pango_layout_is_ellipsized()` to query whether any paragraphs were actually ellipsized.

Since: 1.6

### pango_layout_is_ellipsized ()

    gboolean
    pango_layout_is_ellipsized (PangoLayout *layout);

Queries whether the layout had to ellipsize any paragraphs.

This returns `TRUE` if the ellipsization mode for `layout` is not `PANGO_ELLIPSIZE_NONE`, a positive width is set on `layout` , and there are paragraphs exceeding that width that have to be ellipsized.

#### Parameters

layout | a PangoLayout |

#### Returns

`TRUE` if any paragraphs had to be ellipsized, `FALSE` otherwise.

Since: 1.16

### pango_layout_set_indent ()

    void
    pango_layout_set_indent (PangoLayout *layout,
                             int indent);

Sets the width in Pango units to indent each paragraph. A negative value of `indent` will produce a hanging indentation. That is, the first line will have the full width, and subsequent lines will be indented by the absolute value of `indent` .

The indent setting is ignored if layout alignment is set to `PANGO_ALIGN_CENTER`.

#### Parameters

layout | a PangoLayout. |
indent | the amount by which to indent. |

### pango_layout_get_indent ()

    int
    pango_layout_get_indent (PangoLayout *layout);

Gets the paragraph indent width in Pango units. A negative value indicates a hanging indentation.

#### Parameters

layout | a PangoLayout |

#### Returns

the indent in Pango units.

### pango_layout_get_spacing ()

    int
    pango_layout_get_spacing (PangoLayout *layout);

Gets the amount of spacing between the lines of the layout.

#### Parameters

layout | a PangoLayout |

#### Returns

the spacing in Pango units.

### pango_layout_set_spacing ()

    void
    pango_layout_set_spacing (PangoLayout *layout,
                              int spacing);

Sets the amount of spacing in Pango unit between the lines of the layout.

#### Parameters

layout | a PangoLayout. |
spacing | the amount of spacing |

### pango_layout_set_justify ()

    void
    pango_layout_set_justify (PangoLayout *layout,
                              gboolean justify);

Sets whether each complete line should be stretched to fill the entire width of the layout. This stretching is typically done by adding whitespace, but for some scripts (such as Arabic), the justification may be done in more complex ways, like extending the characters.

Note that this setting is not implemented and so is ignored in Pango older than 1.18.

#### Parameters

layout | a PangoLayout |
justify | whether the lines in the layout should be justified. |

### pango_layout_get_justify ()

    gboolean
    pango_layout_get_justify (PangoLayout *layout);

Gets whether each complete line should be stretched to fill the entire width of the layout.

#### Parameters

layout | a PangoLayout |

#### Returns

the justify.

### pango_layout_set_auto_dir ()

    void
    pango_layout_set_auto_dir (PangoLayout *layout,
                               gboolean auto_dir);

Sets whether to calculate the bidirectional base direction for the layout according to the contents of the layout; when this flag is on (the default), then paragraphs in `layout` that begin with strong right-to-left characters (Arabic and Hebrew principally), will have right-to-left layout, paragraphs with letters from other scripts will have left-to-right layout. Paragraphs with only neutral characters get their direction from the surrounding paragraphs.

When `FALSE`, the choice between left-to-right and right-to-left layout is done according to the base direction of the layout's PangoContext. (See `pango_context_set_base_dir()`).

When the auto-computed direction of a paragraph differs from the base direction of the context, the interpretation of `PANGO_ALIGN_LEFT` and `PANGO_ALIGN_RIGHT` are swapped.

#### Parameters

layout | a PangoLayout |
auto_dir | if `TRUE`, compute the bidirectional base direction from the layout's contents. |

Since: 1.4

### pango_layout_get_auto_dir ()

    gboolean
    pango_layout_get_auto_dir (PangoLayout *layout);

Gets whether to calculate the bidirectional base direction for the layout according to the contents of the layout. See `pango_layout_set_auto_dir()`.

#### Parameters

layout | a PangoLayout |

#### Returns

`TRUE` if the bidirectional base direction is computed from the layout's contents, `FALSE` otherwise.

Since: 1.4

### pango_layout_set_alignment ()

    void
    pango_layout_set_alignment (PangoLayout *layout,
                                PangoAlignment alignment);

Sets the alignment for the layout: how partial lines are positioned within the horizontal space available.

#### Parameters

layout | a PangoLayout |
alignment | the alignment |

### pango_layout_get_alignment ()

    PangoAlignment
    pango_layout_get_alignment (PangoLayout *layout);

Gets the alignment for the layout: how partial lines are positioned within the horizontal space available.

#### Parameters

layout | a PangoLayout |

#### Returns

the alignment.

### pango_layout_set_tabs ()

    void
    pango_layout_set_tabs (PangoLayout *layout,
                           PangoTabArray *tabs);

Sets the tabs to use for `layout` , overriding the default tabs (by default, tabs are every 8 spaces). If `tabs` is `NULL`, the default tabs are reinstated. `tabs` is copied into the layout; you must free your copy of `tabs` yourself.

#### Parameters

layout | a PangoLayout |
tabs | a PangoTabArray, or `NULL`. | [allow-none]

### pango_layout_get_tabs ()

    PangoTabArray *
    pango_layout_get_tabs (PangoLayout *layout);

Gets the current PangoTabArray used by this layout. If no PangoTabArray has been set, then the default tabs are in use and `NULL` is returned. Default tabs are every 8 spaces. The return value should be freed with `pango_tab_array_free()`.

#### Parameters

layout | a PangoLayout |

#### Returns

a copy of the tabs for this layout, or `NULL`.

[nullable]

### pango_layout_set_single_paragraph_mode ()

    void
    pango_layout_set_single_paragraph_mode
                                   (PangoLayout *layout,
                                    gboolean setting);

If `setting` is `TRUE`, do not treat newlines and similar characters as paragraph separators; instead, keep all text in a single paragraph, and display a glyph for paragraph separator characters. Used when you want to allow editing of newlines on a single text line.

#### Parameters

layout | a PangoLayout |
setting | new setting |

### pango_layout_get_single_paragraph_mode ()

    gboolean
    pango_layout_get_single_paragraph_mode
                                   (PangoLayout *layout);

Obtains the value set by `pango_layout_set_single_paragraph_mode()`.

#### Parameters

layout | a PangoLayout |

#### Returns

`TRUE` if the layout does not break paragraphs at paragraph separator characters, `FALSE` otherwise.

### pango_layout_get_unknown_glyphs_count ()

    int
    pango_layout_get_unknown_glyphs_count (PangoLayout *layout);

Counts the number unknown glyphs in `layout` . That is, zero if glyphs for all characters in the layout text were found, or more than zero otherwise.

This function can be used to determine if there are any fonts available to render all characters in a certain string, or when used in combination with `PANGO_ATTR_FALLBACK`, to check if a certain font supports all the characters in the string.

#### Parameters

layout | a PangoLayout |

#### Returns

The number of unknown glyphs in `layout` .

Since: 1.16

### pango_layout_get_log_attrs ()

    void
    pango_layout_get_log_attrs (PangoLayout *layout,
                                PangoLogAttr **attrs,
                                gint *n_attrs);

Retrieves an array of logical attributes for each character in the `layout` .

#### Parameters

layout | a PangoLayout |
attrs | location to store a pointer to an array of logical attributes This value must be freed with `g_free()`. | [out][array length=n_attrs][transfer container]
n_attrs | location to store the number of the attributes in the array. (The stored value will be one more than the total number of characters in the layout, since there need to be attributes corresponding to both the position before the first character and the position after the last character.). | [out]

### pango_layout_get_log_attrs_readonly ()

    const PangoLogAttr *
    pango_layout_get_log_attrs_readonly (PangoLayout *layout,
                                         gint *n_attrs);

Retrieves an array of logical attributes for each character in the `layout` .

This is a faster alternative to `pango_layout_get_log_attrs()`. The returned array is part of `layout` and must not be modified. Modifying the layout will invalidate the returned array.

The number of attributes returned in `n_attrs` will be one more than the total number of characters in the layout, since there need to be attributes corresponding to both the position before the first character and the position after the last character.

#### Parameters

layout | a PangoLayout |
n_attrs | location to store the number of the attributes in the array. | [out]

#### Returns

an array of logical attributes.

### pango_layout_index_to_pos ()

    void
    pango_layout_index_to_pos (PangoLayout *layout,
                               int index_,
                               PangoRectangle *pos);

Converts from an index within a PangoLayout to the onscreen position corresponding to the grapheme at that index, which is represented as rectangle. Note that `pos->x` is always the leading edge of the grapheme and `pos->x + pos->width` the trailing edge of the grapheme. If the directionality of the grapheme is right-to-left, then `pos->width` will be negative.

#### Parameters

layout | a PangoLayout |
index_ | byte index within `layout` |
pos | rectangle in which to store the position of the grapheme. | [out]

### pango_layout_index_to_line_x ()

    void
    pango_layout_index_to_line_x (PangoLayout *layout,
                                  int index_,
                                  gboolean trailing,
                                  int *line,
                                  int *x_pos);

Converts from byte `index_` within the `layout` to line and X position. (X position is measured from the left edge of the line)

#### Parameters

layout | a PangoLayout |
index_ | the byte index of a grapheme within the layout. |
trailing | an integer indicating the edge of the grapheme to retrieve the position of. If > 0, the trailing edge of the grapheme, if 0, the leading of the grapheme. |
line | location to store resulting line index. (which will between 0 and pango_layout_get_line_count(layout) - 1), or `NULL`. | [out][allow-none]
x_pos | location to store resulting position within line (`PANGO_SCALE` units per device unit), or `NULL`. | [out][allow-none]

### pango_layout_xy_to_index ()

    gboolean
    pango_layout_xy_to_index (PangoLayout *layout,
                              int x,
                              int y,
                              int *index_,
                              int *trailing);

Converts from X and Y position within a layout to the byte index to the character at that logical position. If the Y position is not inside the layout, the closest position is chosen (the position will be clamped inside the layout). If the X position is not within the layout, then the start or the end of the line is chosen as described for `pango_layout_line_x_to_index()`. If either the X or Y positions were not inside the layout, then the function returns `FALSE`; on an exact hit, it returns `TRUE`.

#### Parameters

layout | a PangoLayout |
x | the X offset (in Pango units) from the left edge of the layout. |
y | the Y offset (in Pango units) from the top edge of the layout |
index_ | location to store calculated byte index. | [out]
trailing | location to store a integer indicating where in the grapheme the user clicked. It will either be zero, or the number of characters in the grapheme. 0 represents the leading edge of the grapheme. | [out]

#### Returns

`TRUE` if the coordinates were inside text, `FALSE` otherwise.

### pango_layout_get_cursor_pos ()

    void
    pango_layout_get_cursor_pos (PangoLayout *layout,
                                 int index_,
                                 PangoRectangle *strong_pos,
                                 PangoRectangle *weak_pos);

Given an index within a layout, determines the positions that of the strong and weak cursors if the insertion point is at that index. The position of each cursor is stored as a zero-width rectangle. The strong cursor location is the location where characters of the directionality equal to the base direction of the layout are inserted. The weak cursor location is the location where characters of the directionality opposite to the base direction of the layout are inserted.

#### Parameters

layout | a PangoLayout |
index_ | the byte index of the cursor |
strong_pos | location to store the strong cursor position (may be `NULL`). | [out][allow-none]
weak_pos | location to store the weak cursor position (may be `NULL`). | [out][allow-none]

### pango_layout_move_cursor_visually ()

    void
    pango_layout_move_cursor_visually (PangoLayout *layout,
                                       gboolean strong,
                                       int old_index,
                                       int old_trailing,
                                       int direction,
                                       int *new_index,
                                       int *new_trailing);

Computes a new cursor position from an old position and a count of positions to move visually. If `direction` is positive, then the new strong cursor position will be one position to the right of the old cursor position. If `direction` is negative, then the new strong cursor position will be one position to the left of the old cursor position.

In the presence of bidirectional text, the correspondence between logical and visual order will depend on the direction of the current run, and there may be jumps when the cursor is moved off of the end of a run.

Motion here is in cursor positions, not in characters, so a single call to `pango_layout_move_cursor_visually()` may move the cursor over multiple characters when multiple characters combine to form a single grapheme.

#### Parameters

layout | a PangoLayout. |
strong | whether the moving cursor is the strong cursor or the weak cursor. The strong cursor is the cursor corresponding to text insertion in the base direction for the layout. |
old_index | the byte index of the grapheme for the old index |
old_trailing | if 0, the cursor was at the leading edge of the grapheme indicated by `old_index` , if > 0, the cursor was at the trailing edge. |
direction | direction to move cursor. A negative value indicates motion to the left. |
new_index | location to store the new cursor byte index. A value of -1 indicates that the cursor has been moved off the beginning of the layout. A value of `G_MAXINT` indicates that the cursor has been moved off the end of the layout. | [out]
new_trailing | number of characters to move forward from the location returned for `new_index` to get the position where the cursor should be displayed. This allows distinguishing the position at the beginning of one line from the position at the end of the preceding line. `new_index` is always on the line where the cursor should be displayed. | [out]

### pango_layout_get_extents ()

    void
    pango_layout_get_extents (PangoLayout *layout,
                              PangoRectangle *ink_rect,
                              PangoRectangle *logical_rect);

Computes the logical and ink extents of `layout` . Logical extents are usually what you want for positioning things. Note that both extents may have non-zero x and y. You may want to use those to offset where you render the layout. Not doing that is a very typical bug that shows up as right-to-left layouts not being correctly positioned in a layout with a set width.

The extents are given in layout coordinates and in Pango units; layout coordinates begin at the top left corner of the layout.

#### Parameters

layout | a PangoLayout |
ink_rect | rectangle used to store the extents of the layout as drawn or `NULL` to indicate that the result is not needed. | [out][allow-none]
logical_rect | rectangle used to store the logical extents of the layout or `NULL` to indicate that the result is not needed. | [out][allow-none]

### pango_layout_get_pixel_extents ()

                                    PangoRectangle *logical_rect);

Computes the logical and ink extents of `layout` in device units. This function just calls `pango_layout_get_extents()` followed by two `pango_extents_to_pixels()` calls, rounding `ink_rect` and `logical_rect` such that the rounded rectangles fully contain the unrounded one (that is, passes them as first argument to `pango_extents_to_pixels()`).

#### Parameters

layout | a PangoLayout |
ink_rect | rectangle used to store the extents of the layout as drawn or `NULL` to indicate that the result is not needed. | [out][allow-none]
logical_rect | rectangle used to store the logical extents of the layout or `NULL` to indicate that the result is not needed. | [out][allow-none]

### pango_layout_get_size ()

                           int *height);

Determines the logical width and height of a PangoLayout in Pango units (device units scaled by `PANGO_SCALE`). This is simply a convenience function around `pango_layout_get_extents()`.

#### Parameters

layout | a PangoLayout |
width | location to store the logical width, or `NULL`. | [out][allow-none]
height | location to store the logical height, or `NULL`. | [out][allow-none]

### pango_layout_get_pixel_size ()

    void
    pango_layout_get_pixel_size (PangoLayout *layout,

                                 int *height);

Determines the logical width and height of a PangoLayout in device units. (`pango_layout_get_size()` returns the width and height scaled by `PANGO_SCALE`.) This is simply a convenience function around `pango_layout_get_pixel_extents()`.

#### Parameters

layout | a PangoLayout |
width | location to store the logical width, or `NULL`. | [out][allow-none]
height | location to store the logical height, or `NULL`. | [out][allow-none]

### pango_layout_iter_get_index ()

    int
    pango_layout_iter_get_index (PangoLayoutIter *iter);

Gets the current byte index. Note that iterating forward by char moves in visual order, not logical order, so indexes may not be sequential. Also, the index may be equal to the length of the text in the layout, if on the `NULL` run (see `pango_layout_iter_get_run()`).

#### Parameters

iter | a PangoLayoutIter |

#### Returns

current byte index.

### pango_layout_iter_get_baseline ()

    pango_layout_iter_get_run_readonly (PangoLayoutIter *iter);

Gets the current run. When iterating by run, at the end of each line, there's a position with a `NULL` run, so this function can return `NULL`. The `NULL` run at the end of each line ensures that all lines have at least one run, even lines consisting of only a newline.

This is a faster alternative to `pango_layout_iter_get_run()`, but the user is not expected to modify the contents of the run (glyphs, glyph widths, etc.).

#### Parameters

iter | a PangoLayoutIter |

#### Returns

the current run, that should not be modified.

Gets the extents of the current character, in layout coordinates (origin is the top left of the entire layout). Only logical extents can sensibly be obtained for characters; ink extents make sense only down to the level of clusters.

#### Parameters

iter | a PangoLayoutIter |
logical_rect | rectangle to fill with logical extents. | [out caller-allocates]

### pango_layout_iter_get_cluster_extents ()

    void

Divides the vertical space in the PangoLayout being iterated over between the lines in the layout, and returns the space belonging to the current line. A line's range includes the line's logical extents, plus half of the spacing above and below the line, if `pango_layout_set_spacing()` has been called to set layout spacing. The Y positions are in layout coordinates (origin at top left of the entire layout).

                                        PangoRectangle *logical_rect);

Obtains the extents of the current line. `ink_rect` or `logical_rect` can be `NULL` if you aren't interested in them. Extents are in layout coordinates (origin is the top-left corner of the entire PangoLayout). Thus the extents returned by this function will be the same width/height but not at the same x/y as the extents returned from `pango_layout_line_get_extents()`.

                                   PangoRectangle *logical_rect);

Computes the logical and ink extents of a layout line. See `pango_font_get_glyph_extents()` for details about the interpretation of the rectangles.

#### Parameters

line | a PangoLayoutLine |
ink_rect | rectangle used to store the extents of the glyph string as drawn, or `NULL`. | [out][allow-none]
logical_rect | rectangle used to store the logical extents of the glyph string, or `NULL`. | [out][allow-none]

### pango_layout_line_get_pixel_extents ()

    void
    pango_layout_line_get_pixel_extents (PangoLayoutLine *layout_line,
                                         PangoRectangle *ink_rect,
                                         PangoRectangle *logical_rect);

Computes the logical and ink extents of `layout_line` in device units. This function just calls `pango_layout_line_get_extents()` followed by two `pango_extents_to_pixels()` calls, rounding `ink_rect` and `logical_rect` such that the rounded rectangles fully contain the unrounded one (that is, passes them as first argument to `pango_extents_to_pixels()`).

#### Parameters

layout_line | a PangoLayoutLine |
ink_rect | rectangle used to store the extents of the glyph string as drawn, or `NULL`. | [out][allow-none]
logical_rect | rectangle used to store the logical extents of the glyph string, or `NULL`. | [out][allow-none]

### pango_layout_line_index_to_x ()

    void
    pango_layout_line_index_to_x (PangoLayoutLine *line,
                                  int index_,
                                  gboolean trailing,
                                  int *x_pos);

Converts an index within a line to a X position.

#### Parameters

line | a PangoLayoutLine |
index_ | byte offset of a grapheme within the layout |
trailing | an integer indicating the edge of the grapheme to retrieve the position of. If > 0, the trailing edge of the grapheme, if 0, the leading of the grapheme. |
x_pos | location to store the x_offset (in Pango unit). | [out]

### pango_layout_line_x_to_index ()

    gboolean
    pango_layout_line_x_to_index (PangoLayoutLine *line,
                                  int x_pos,
                                  int *index_,
                                  int *trailing);

Converts from x offset to the byte index of the corresponding character within the text of the layout. If `x_pos` is outside the line, `index_` and `trailing` will point to the very first or very last position in the line. This determination is based on the resolved direction of the paragraph; for example, if the resolved direction is right-to-left, then an X position to the right of the line (after it) results in 0 being stored in `index_` and `trailing` . An X position to the left of the line results in `index_` pointing to the (logical) last grapheme in the line and `trailing` being set to the number of characters in that grapheme. The reverse is true for a left-to-right line.

#### Parameters

line | a PangoLayoutLine |
x_pos | the X offset (in Pango units) from the left edge of the line. |
index_ | location to store calculated byte index for the grapheme in which the user clicked. | [out]
trailing | location to store an integer indicating where in the grapheme the user clicked. It will either be zero, or the number of characters in the grapheme. 0 represents the leading edge of the grapheme. | [out]

#### Returns

`FALSE` if `x_pos` was outside the line, `TRUE` if inside

### pango_layout_line_get_x_ranges ()

    void
    pango_layout_line_get_x_ranges (PangoLayoutLine *line,
                                    int start_index,
                                    int end_index,
                                    int **ranges,
                                    int *n_ranges);

Gets a list of visual ranges corresponding to a given logical range. This list is not necessarily minimal - there may be consecutive ranges which are adjacent. The ranges will be sorted from left to right. The ranges are with respect to the left edge of the entire layout, not with respect to the line.

#### Parameters

line | a PangoLayoutLine |
start_index | Start byte index of the logical range. If this value is less than the start index for the line, then the first range will extend all the way to the leading edge of the layout. Otherwise it will start at the leading edge of the first character. |
end_index | Ending byte index of the logical range. If this value is greater than the end index for the line, then the last range will extend all the way to the trailing edge of the layout. Otherwise, it will end at the trailing edge of the last character. |
ranges | location to store a pointer to an array of ranges. The array will be of length `2*n_ranges`, with each range starting at `(*ranges)[2*n]` and of width `(*ranges)[2*n + 1] - (*ranges)[2*n]`. This array must be freed with `g_free()`. The coordinates are relative to the layout and are in Pango units. | [out][array length=n_ranges][transfer full]
n_ranges | The number of ranges stored in `ranges` . |

## Types and Values

### PangoLayout

    typedef struct _PangoLayout PangoLayout;

The PangoLayout structure represents an entire paragraph of text. It is initialized with a PangoContext, UTF-8 string and set of attributes for that string. Once that is done, the set of formatted lines can be extracted from the object, the layout can be rendered, and conversion between logical character positions within the layout's text, and the physical position of the resulting glyphs can be made.

There are also a number of parameters to adjust the formatting of a PangoLayout, which are illustrated in Figure 1, “Adjustable parameters for a PangoLayout”. It is possible, as well, to ignore the 2-D setup, and simply treat the results of a PangoLayout as a list of lines.

Figure 1. Adjustable parameters for a PangoLayout

The PangoLayout structure is opaque, and has no user-visible fields.

### PangoLayoutIter

    typedef struct _PangoLayoutIter PangoLayoutIter;

A PangoLayoutIter structure can be used to iterate over the visual extents of a PangoLayout.

The PangoLayoutIter structure is opaque, and has no user-visible fields.

### enum PangoWrapMode

A PangoWrapMode describes how to wrap the lines of a PangoLayout to the desired width.

#### Members

PANGO_WRAP_WORD | wrap lines at word boundaries. |
PANGO_WRAP_CHAR | wrap lines at character boundaries. |
PANGO_WRAP_WORD_CHAR | wrap lines at word boundaries, but fall back to character boundaries if there is not enough space for a full word. |

### PANGO_TYPE_WRAP_MODE

    #define PANGO_TYPE_WRAP_MODE (pango_wrap_mode_get_type ())

### enum PangoEllipsizeMode

The PangoEllipsizeMode type describes what sort of (if any) ellipsization should be applied to a line of text. In the ellipsization process characters are removed from the text in order to make it fit to a given width and replaced with an ellipsis.

#### Members

PANGO_ELLIPSIZE_NONE | No ellipsization |
PANGO_ELLIPSIZE_START | Omit characters at the start of the text |
PANGO_ELLIPSIZE_MIDDLE | Omit characters in the middle of the text |
PANGO_ELLIPSIZE_END | Omit characters at the end of the text |

### PANGO_TYPE_ELLIPSIZE_MODE

    #define PANGO_TYPE_ELLIPSIZE_MODE (pango_ellipsize_mode_get_type ())

### enum PangoAlignment

A PangoAlignment describes how to align the lines of a PangoLayout within the available space. If the PangoLayout is set to justify using `pango_layout_set_justify()`, this only has effect for partial lines.

#### Members

PANGO_ALIGN_LEFT | Put all available space on the right |
PANGO_ALIGN_CENTER | Center the line within the available space |
PANGO_ALIGN_RIGHT | Put all available space on the left |

### PANGO_TYPE_ALIGNMENT

    #define PANGO_TYPE_ALIGNMENT (pango_alignment_get_type ())

### struct PangoLayoutLine

    struct PangoLayoutLine {
      PangoLayout *layout;
      gint         start_index;     /* start of line as byte index into layout->text */
      gint         length;		/* length of line in bytes */
      GSList      *runs;
      guint        is_paragraph_start : 1;  /* TRUE if this is the first line of the paragraph */
      guint        resolved_dir : 3;  /* Resolved PangoDirection of line */
    };

The PangoLayoutLine structure represents one of the lines resulting from laying out a paragraph via PangoLayout. PangoLayoutLine structures are obtained by calling `pango_layout_get_line()` and are only valid until the text, attributes, or settings of the parent PangoLayout are modified.

Routines for rendering PangoLayout objects are provided in code specific to each rendering system.

#### Members

PangoLayout *`layout`; | the layout this line belongs to, might be `NULL`. | [allow-none]
gint `start_index`; | start of line as byte index into layout->text |
gint `length`; | length of line in bytes |
GSList *`runs`; | list of runs in the line, from left to right. | [allow-none][element-type]
guint `is_paragraph_start` : 1; | TRUE if this is the first line of the paragraph |
guint `resolved_dir` : 3; | Resolved PangoDirection of line |

### PangoLayoutRun

    typedef PangoGlyphItem PangoLayoutRun;

The PangoLayoutRun structure represents a single run within a PangoLayoutLine; it is simply an alternate name for PangoGlyphItem. See the PangoGlyphItem docs for details on the fields.
