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\n";
 }
 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.

FILES

This module requires Image::Xpm

$Image::Info::XPM::RGBLIB is set to /usr/X11R6/lib/X11/rgb.txt by default, this is used to resolve textual color names to their RGB counterparts.

NOTES

For more information about XPM see:

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.
