man Image::Info::BMP () - Windows Device Indepdent Bitmap support for Image::Info
NAME
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\n"; } 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 CWimage_info is invoked as CWimage_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.

DIAGNOSTICS
- 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.
