GdkPixbuf.Pixbuf.new_from_file_at_scale
Description: Reference for GdkPixbuf.Pixbuf.new_from_file_at_scale

### Constructor

# GdkPixbuf Pixbufnew_from_file_at_scale

#### Declaration [src]

    GdkPixbuf*
    gdk_pixbuf_new_from_file_at_scale (
      const char* filename,
      int width,
      int height,
      gboolean preserve_aspect_ratio,
      GError** error
    )

#### Description [src]

Creates a new pixbuf by loading an image from a file.

The file format is detected automatically.

If `NULL` is returned, then `error` will be set. Possible errors are:

- the file could not be opened
- there is no loader for the file’s format
- there is not enough memory to allocate the image buffer
- the image buffer contains invalid data

The error domains are `GDK_PIXBUF_ERROR` and `G_FILE_ERROR`.

The image will be scaled to fit in the requested size, optionally preserving the image’s aspect ratio.

When preserving the aspect ratio, a `width` of -1 will cause the image to be scaled to the exact given height, and a `height` of -1 will cause the image to be scaled to the exact given width. When not preserving aspect ratio, a `width` or `height` of -1 means to not scale the image at all in that dimension. Negative values for `width` and `height` are allowed since 2.8.

Available since: | 2.6

#### Parameters

`filename` | `const char*`
| Name of file to load, in the GLib file name encoding.
| The data is owned by the caller of the function.
| The value is a file system path, using the OS encoding.
`width` | `int`
| The width the image should have or -1 to not constrain the width.
`height` | `int`
| The height the image should have or -1 to not constrain the height.
`preserve_aspect_ratio` | `gboolean`
| `TRUE` to preserve the image’s aspect ratio.
`error` | `GError **`
| The return location for a `GError*`, or `NULL`.

#### Return value

Returns: | `GdkPixbuf`
| A newly-created pixbuf.
| The caller of the function takes ownership of the data, and is responsible for freeing it.
| The return value can be `NULL`.
