Image::Info::BMP - Windows Device Indepdent Bitmap support for Image::Info SYNOPSIS
use Image::Info qw(image_info dim); my $info = image_info("image.bmp"); if (my $error = $info->{error}) { die "Can't parse image info: $error "; } my $color = $info->{color_type}; my($w, $h) = dim($info); DESCRIPTION
This modules supplies the standard key names except for Gamma, Interlace, LastModificationTime, as well as: BMP_ColorsImportant Specifies the number of color indexes that are required for displaying the bitmap. If this value is zero, all colors are required. BMP_Origin If true the bitmap is a bottom-up DIB and its origin is the lower-left corner. Otherwise, the bitmap is a top-down DIB and its origin is the upper-left corner. 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. If 0 then this is a true color image. The number of color available is 2 ^ BitsPerSample. METHODS
process_file() $info->process_file($source, $options); Processes one file and sets the found info fields in the $info object. SEE ALSO

Size mismatch The image may be correct, the filesize does not match the internally stored value. BUGS
The current implementation only function on little-endian architectures. Consequently erroneous data concerning compression (including file_ext and file_mime_type) may be reported. AUTHOR

Image::Info::XPM(3) User Contributed Perl Documentation Image::Info::XPM(3) 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 "; } 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. AUTHOR
