dia — a diagram drawing program
dia  [-c] [--credits] [-e ] [OUTPUT--export=] [OUTPUT-L ] [LAYER,LAYER,...--show-layers=] [LAYER,LAYER,...-h] [--help] [-n] [--nosplash] [-s ] [WxH--size=] [WxH-t ] [FORMAT--filter=] [FORMAT-v] [--version] [file ...]
Dia is used to create diagrams. Dia has a number of basic tools, like lines and boxes but can also dynamically load sheets. A sheet is a collection of tools that are used in a certain type of diagram.
Most diagram objects in Dia have connection points. Lines can be connected to these connection points and this way graph structures can be formed. When objects are moved or resized the connections will follow the objects.
Diagrams drawn in Dia can be exported as PostScript.
Dia accepts the following options:
-c
	  --creditsDisplay credits list and exit.
-e OUTPUT
	  --export=OUTPUTExport loaded file to OUTPUT and exit.
-h
	  --helpDisplay a list of all commandline options.
-n
	  --nosplashDo not show the splash screen.
-s WxH
	  --size=WxHExport loaded file in decimal given width and/or
	  height.  It is allowed to only select width or height.
	  E.g. --size=
	  exports an image that is 520 pixels wide, while
	  520x--size=
	  exports an image of 900 pixels height.x900
| ![[Note]](images/note.png) | |
| This option is currently only implemented for the PNG export filter. | 
-L LAYER,LAYER,...
	  --show-layers=LAYER,LAYER,...Only include specified layers when exporting. Layers can be specified either as a layer name, the layer number or a numeric range X-Y of layers. --show-layers=background,2-5 shows the layer named background and layers 2-5, --show-layers=2- shows layers 2 and up.
-t FORMAT
	  --export-to-format=FORMATExport loaded file in FORMAT and exit. Format are described below.
-v
	  --versionDisplay dia version and exit.
The following export formats are supported by dia.
cgm (Computer Graphics Metafile, ISO
        8632)
dia (Native dia diagram)
dxf (Drawing Interchange File)
eps  or
	eps-builtin or eps-pango
	(Encapsulated PostScript)
The format specifications eps and eps-pango both
	use the font renderer of the Pango library, while
        eps-builtin uses a dia specific font
        renderer.  If you have problems with Pango rendering,
        e.g. Unicode, try eps-builtin
	instead.
fig (XFig format)
mp (TeX MetaPost macros)
plt or hpgl (HP
	Graphics Language)
png (Portable Network
	Graphics)
shape (Dia Shape File)
svg (Scalable Vector Graphics)
tex (TeX PSTricks macros)
wpg (WordPerfect Graphics)
wmf (Windows MetaFile)
dia creates a directory

        values for elements (XML format).
diarc: keeps
        dia preferences (ASCII).
history: keeps the list of last
        edited diagrams (ASCII).
menurc: contains an automated
	accelerator map dump (Lisp).
persistence: contains GUI
	information, e.g. open windows (XML).
