Image::Info::XPM(3)	       User Contributed Perl Documentation	      Image::Info::XPM(3)

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($file, 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 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.

METHODS
   process_file()
	       $info->process_file($source, $options);

       Processes one file and sets the found info fields in the $info object.

FILES
       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.

SEE ALSO
       Image::Info, Image::Xpm

NOTES
       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 XPMs
       (Versions 1-3), if this is the case try inserting /* XPM */ as the first line.
