DESCRIPTION

20       This modules supplies the standard key names except for Compression,
21       Gamma, Interlace, LastModificationTime, as well as:
22
23       ColorPalette
24           Reference to an array of all colors used.  This key is only present
25           if "image_info" is invoked as "image_info({ColorPalette>=1})".
26
27       ColorTableSize
28           The number of colors the image uses.
29
30       HotSpotX
31           The x-coord of the image's hotspot.  Set to -1 if there is no
32           hotspot.
33
34       HotSpotY
35           The y-coord of the image's hotspot.  Set to -1 if there is no
36           hotspot.
37
38       L1D_Histogram
39           Reference to an array representing a one dimensioanl luminance
40           histogram. This key is only present if "image_info" is invoked as
41           "image_info($file, L1D_Histogram=>1)". The range is from 0 to 255,
42           however auto-vivification is used so a null field is also 0, and
43           the array may not actually contain 255 fields.
44
45       XPM_CharactersPerPixel
46           This is typically 1 or 2. See Image::Xpm.
47
48       XPM_Extension-.*
49           XPM Extensions (the most common is XPMEXT) if present.
50

60
61       $Image::Info::XPM::RGBLIB is set to /usr/share/X11/rgb.txt by default,
62       this is used to resolve textual color names to their RGB counterparts.

CAVEATS

73       While the module attempts to be as robust as possible, it may not
74       recognize older XBMs (Versions 1-3), if this is the case try inserting
75       /* XPM */ as the first line.
