I’m working on a project that might require me to compute the DCT of the image. Hence the question.
-> Is there a fast way of pixel-by-pixel proceccing images in PHP
I think it would be best to process the files using another language instead of PHP or library/application such as – ImageMagick php.net/manual/en/book.imagick.php.
I’ve never used this myself, so don’t really know performance issues.
Also -> wideimage.sourceforge.net/
The GD functions, as described in the previous answer, are quite slow, and sometimes can take a huge chunk of the CPU for processing.
Take a look here for seperate benchmarks etc:
