Image::Size is a library based on the image-sizing code in the wwwimagesize script, a tool that analyzes HTML files and adds HEIGHT and WIDTH tags to IMG directives.
Image::Size has generalized that code to return a raw (X, Y) pair, and included wrappers to pre-format that output into either HTML or a set of attribute pairs suitable for the CGI.pm library by Lincoln Stein.
Currently, Image::Size can size images in XPM, XBM, GIF, JPEG, PNG, MNG, TIFF, the PPM family of formats (PPM/PGM/PBM) and if Image::Magick is installed, the formats supported by it.
