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.
