Image::Info::XPM - XPM support for Image::Info
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);
This modules supplies the standard key names except for Compression, Gamma, Interlace, LastModificationTime, as well as:
Reference to an array of all colors used. This key is only present if image_info is invoked as image_info($file, ColorPalette>=1).
image_info
image_info($file, ColorPalette>=1)
The number of colors the image uses.
The x-coord of the image's hotspot. Set to -1 if there is no hotspot.
The y-coord of the image's hotspot. Set to -1 if there is no hotspot.
Reference to an array representing a one dimensional luminance histogram. This key is only present if image_info is invoked as image_info($file, L1D_Histogram=>1). The range is from 0 to 255, however auto-vivification is used so a null field is also 0, and the array may not actually contain 255 fields.
image_info($file, L1D_Histogram=>1)
This is typically 1 or 2. See Image::Xpm.
XPM Extensions (the most common is XPMEXT) if present.
$info->process_file($source, $options);
Processes one file and sets the found info fields in the $info object.
$info
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.
_get_rgb_txt
Image::Info, Image::Xpm
For more information about XPM see ftp://ftp.x.org/contrib/libraries/xpm-README.html
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.
