Image::Info::XPM(3) XPM support for Image::Info

SYNOPSIS


use Image::Info qw(image_info dim);
my $info = image_info("image.xpm");

}
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.

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.
