Greetings earthlings,
Please find at GNU ELPA version 1.0.0 of xpm.el (et al):
http://elpa.gnu.org/packages/xpm.html
As this is the initial release, there is no substantial NEWS.
Instead, i include here for the web-disinclined the full xpm.el
Commentary (note important :-D links at bottom):
This package makes editing XPM images easy (and maybe fun).
Editing is done directly on the (textual) image format,
for maximal cohesion w/ the Emacs Way.
Coordinates have the form (X . Y), with X from 0 to (width-1),
and Y from 0 to (height-1), inclusive, in the 4th quadrant;
i.e., X grows left to right, Y top to bottom, origin top-left.
(0,0) … (width-1,0)
⋮ ⋮
(0,height-1) … (width-1,height-1)
In xpm.el (et al), "px" stands for "pixel", a non-empty string
in the external representation of the image. The px length is
the image's "cpp" (characters per pixel). The "palette" is a
set of associations between a px and its "color", which is an
alist with symbolic TYPE and and string CVALUE. TYPE is one of:
c -- color (most common)
s -- symbolic
g -- grayscale
g4 -- four-level grayscale
m -- monochrome
and CVALUE is a string, e.g., "blue" or "#0000FF". Two images
are "congruent" if their width, height and cpp are identical.
This package was originally conceived for non-interactive use,
so its design is spartan at the core. However, we plan on
adding a XPM mode in a future release; see HACKING link below.
For now, the features (w/ correspondingly-named files) are:
- xpm -- edit XPM images
- xpm-m2z -- ellipse/circle w/ fractional center
Some things are autoloaded. Which ones? Use the source, Luke!
(Alternatively, just ask on help-gnu-emacs (at gnu dot org).)

Lastly, the adventurous might also find interesting:

If you are not adventurous, you might find the screenshot of xpm in
action at the Tip Jar link pleasant to pass your eyes over, anyway.
