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 has handles. Lines can be connected to these handles 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 PostScript.
Dia accepts the following options:
Display credits list and exit.
Export loaded file to OUTPUT and exit.
Display a list of all commandline options.
Do not show the splash screen.
Export loaded file in FORMAT and exit. Format are described below.
Size for exported bitmap graphics.
Display 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 all 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 .dia in the user's home, which contains different files to store user preferences. To reset dia to it's default behaviour, just remove the respective file:
defaults.dia: contains default 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).
pluginrc: the list of loaded plugins (XML).
