Image::Info::BMP(3)	       User Contributed Perl Documentation	      Image::Info::BMP(3)

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 "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
       Image::Info

NOTES
       For more information about BMP see <http://msdn.microsoft.com>.

       Random notes:

	 warn if height is negative and compress is not RGB or BITFILEDS (0 or 3)
	 ICO and CUR support?
	 ### v5
	 If bit depth is 0, it relies upon underlying JPG/PNG :-(

	   DWORD	bV5GammaBlue;

	   DWORD	bV5ProfileData;
	   DWORD	bV5ProfileSize;

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.
