"How to edit an executable's desktop icon"
Sometimes people want to know how to edit an X bitmap or to create a new one. See Paul Obermeier's http://www.posoft.de/ 's poBitmap, part of poSoft utilities for one tool.
KPV See Bitmap Editor for a simple tool to create and edit bitmaps.

A variant Tk-pertinent sense of "bitmap" is as a permissible argument to specific canvas subcommands. A model of such uses is

While Tk offers many interesting bitmap capabilities, it can be difficult tracking down their documentation. A good starting point is the distribution man page for the library entry point Tk_GetBitmap [L1 ]. Along with much else, it provides a list--"error", "gray50", "question", and so on--of standard bitmaps built in to Tk. Apparently Tk provides no script-level introspection to access this list. To view these built-ins, therefore, it's necessary to perform something like the script below. Note, however, that the last 16 bitmaps (from document to caution) are only available on the Mac platform.
set bitmap_list {error gray75 gray50 gray25 gray12 hourglass

eval destroy [winfo children .]
canvas .c -height 200 -width 200 -background linen
listbox .l -height [llength $bitmap_list]
foreach bitmap $bitmap_list {
.l insert end $bitmap
}

bind .l <ButtonRelease-1> show_bitmap
proc show_bitmap {} {
set pattern [.l get [.l curselection]]
.c delete bitmap
.c create bitmap 100 100 -bitmap $pattern -tags bitmap
}Run this and you'll see such pictures as ...
