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: Specifies the number of color indexes that are required for displaying the bitmap. If this value is zero, all colors are required. 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. Reference to an array of all colors used. This key is only present if `image_info' is invoked as `image_info($file, ColorPalette=>1)'. The number of colors the image uses. If 0 then this is a true color image. The number of color available is 2 ^ BitsPerSample.

The image may be correct, the filesize does not match the internally stored value.
