Image::Info::XPM(3) User Contributed Perl Documentation Image::Info::XPM(3)NAMEImage::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({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.
METHODSprocess_file()
$info->process_file($source, $options);
Processes one file and sets the found info fields in the $info object.
AUTHORFILES

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.
