XPM (X PixMap) is a powerful and portable format for
storing/retrieving pixmaps to/from files. It provides the easiest
way to load a graphical image into a GTK+ application. Moreover, the
graphical data can be embedded in the application itself.
Briefly, the XPM format consists of a string describing its
dimensions and number of colors, followed by the color table, and
finally by the image data utilizing the characters mapped in the
color table. Here's a sample:
"16 16 6 1",
" c None s None",
". c black",
"X c red",
"o c yellow",
"O c #808080",
"# c white",
" ",
" .. ",
" ..XX. ",
" ..XXXXX. ",
" ..XXXXXXXX. ",
".ooXXXXXXXXX. ",
"..ooXXXXXXXXX. ",
".X.ooXXXXXXXXX. ",
".XX.ooXXXXXX.. ",
" .XX.ooXXX..#O ",
" .XX.oo..##OO. ",
" .XX..##OO.. ",
" .X.#OO.. ",
" ..O.. ",
" .. ",
