Xref: usenet.cise.ufl.edu comp.lang.perl.announce:15 comp.lang.perl.modules:661 Version 2.4 of Image::Size has been uploaded to PAUSE, and will propagate to all CPAN sites over the next few days. To build and install, you will need perl 5.002 or later, and sufficient access to install an extension. Summary of Changes in 2.4: * Small bug in jpegsize, not returning the string 'JPG' as the third element of the returned list. Figures I have a half-documented feature, and someone actually uses it. :-) >From the README file for 2.4: 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 and the PPM family of formats (PPM/PGM/PBM). I did this because my WWW server generates a lot of documents on demand rather than keeping them in static files. These documents not only use directional icons and buttons, but other graphics to annotate and highlight sections of the text. Without size attributes, browsers cannot render the text of a page until the image data is loaded and the size known for layout. This library enables scripts to size their images at run-time and include that as part of the generated HTML. Or for any other utility that uses and manipulates graphics. The idea of the basic interface + wrappers is to not limit the programmer to a certain data format. Please send any reports of problems or bugs to rjray@uswest.com. I wouldn't mind a short note to know that you're using this, just so I can justify its continued development to my manager :-). (In seriousness, a rough idea of how many others are using this will help promote its upkeep.)
