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.
