gd is the correct tool for your job. But there are some caveats. You will need to be using gd-2.0 or better to get satisfactory results for this sort of work. gd-2.0.1 supports: bicubic interpolation for scaling images 24-bit (true colour) images Make sure your images aren't being converted to 8-bit at any stage of the scaling/cropping process. Use ImageCreateTrueColor to create images. Oh, and there's a bug in either php-4.1.2 or gd-2.0.1 where scaling and cropping with one operation using imagecopyresampled fails. I use a work-around of cropping with imagecopyresized and then scaling with imagecopyresampled. The large file sizes could be improved by reducing the quality of the JPEG compression. Also, once the images have been scaled smoothly, there will be fewer sharp edges allowing JPEG compression to be more efficient. ...R. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
