Note Submitter: bill_b ---- Could someone shed some light about what is the best options to use for the $filters value to minimize file size. Here is what we are trying to achieve: - end-user uploads a large screenshot image (1024 x 768) of a software application. Most of these screenshots will probably have more than 256 colors. - We want to create different versions of that uploaded image at different sizes: the initial size, 640x480, 320x240, 120x90, without losing quality, but with the smallest possible file size. My understanding is that we should use: - $quality = 9 - what about for $filters?
