XPM is a popular X Window image file format for storing color icons. The Pixmap image type can be used
to create color images using XPM files.
Pixmaps support the following options:
-data => string
Specifies the contents of the source pixmap as a string. The string must adhere to the XPM file
format (e.g., as generated by the pixmap(1) program). If both the -data and -file options are
specified, the -data option takes precedence. Please note that the XPM file parsing code in the xpm
library is somewhat fragile. The first line of the string must be "/*XPM */" or otherwise a
segmatation fault will be caused.
-file => namename gives the name of a file whose contents define the source pixmap. The file must adhere to the
XPM file format (e.g., as generated by the pixmap(1) program).
