Image::Info::XPM.3pm

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({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.

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.
