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($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 asimage_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 asimage_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.

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.
