Image::Info::ASCII - ASCII support for Image::Info

NAME

Image::Info::ASCII - ASCII support for Image::Info

SYNOPSIS

 use Image::Info qw(image_info dim);

 my $info = image_info("image.txt");
 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.

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 127, however auto-vivification is used so a null field is also 0, and the array may not actually contain 127 fields. The index in the array corresponds to the ord of the character and thusly fields 0-8,11,12,14-31 should always be blank.

While not immediately obvious, this could be used to accquire information about a normal text file and it's language. Though it would likely have to be English, Hawaiian, Swahili, or Latin (unless you can be assured that no 8th bit characters occur in the first 32 bytes of the source).

BUGS

Other than being completely functional yet potentially useless?
