|ColorPalette||Reference to an array of all colors used. This key is only present if image_info is invoked as image_info($file, ColorPalette>=1).|
|ColorTableSize||The number of colors the image uses.|
|HotSpotX||The x-coord of the images hotspot. Set to -1 if there is no hotspot.|
|HotSpotY||The y-coord of the images hotspot. Set to -1 if there is no hotspot.|
|L1D_Histogram||Reference to an array representing a one dimensional luminance histogram. This key is only present if image_info is invoked as image_info($file, L1D_Histogram=>1). The range is from 0 to 255, however auto-vivification is used so a null field is also 0, and the array may not actually contain 255 fields.|
|XPM_CharactersPerPixel||This is typically 1 or 2. See Image::Xpm.|
|XPM_Extension-.*||XPM Extensions (the most common is XPMEXT) if present.|
Processes one file and sets the found info fields in the $info object.
This module requires Image::Xpm
$Image::Info::XPM::RGBLIB is set to /usr/X11R6/lib/X11/rgb.txt or an equivalent path (see the _get_rgb_txt function for the complete list) by default, this is used to resolve textual color names to their RGB counterparts.
For more information about XPM see <ftp://ftp.x.org/contrib/libraries/xpm-README.html>
While the module attempts to be as robust as possible, it may not recognize older XPMs (Versions 1-3), if this is the case try inserting /* XPM */ as the first line.
