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 CWimage_info is invoked as CWimage_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 CWimage_info is invoked as CWimage_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.

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.
