Image::Info::XPM(3pm) User Contributed Perl Documentation Image::Info::XPM(3pm) NAME
Image::Info::XPM - XPM support for Image::Info SYNOPSIS
use Image::Info qw(image_info dim); my $info = image_info("image.xpm"); if (my $error = $info->{error}) { die "Can't parse image info: $error "; } my $color = $info->{color_type}; my($w, $h) = dim($info); DESCRIPTION
This modules supplies the standard key names except for Compression, Gamma, Interlace, LastModificationTime, as well as: ColorPalette Reference to an array of all colors used. This key is only present if "image_info" is invoked as "image_info({ColorPalette>=1})". ColorTableSize The number of colors the image uses. HotSpotX The x-coord of the image's hotspot. Set to -1 if there is no hotspot. HotSpotY The y-coord of the image's hotspot. Set to -1 if there is no hotspot. L1D_Histogram Reference to an array representing a one dimensioanl 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. METHODS
process_file() $info->process_file($source, $options); Processes one file and sets the found info fields in the $info object. AUTHOR

For more information about XPM see: ftp://ftp.x.org/contrib/libraries/xpm-README.html CAVEATS
While the module attempts to be as robust as possible, it may not recognize older XBMs (Versions 1-3), if this is the case try inserting /* XPM */ as the first line. AUTHOR
