I'm not sure if this is the correct forum for this post, but none of the others seemed to fit either. Here is my situation: I am the programmer for a website that maintains images. I need to modify the images "on the fly", and I've done what needs to be done using a php module called GD2. The problem is this: the saved JPEG images, even when saved at quality=100, are no match for the images as saved via photoshop. The website runs php code under Apache in a Linuz environment.
So, my question is this: what image manipulation tool is available to me in that environment (php, Apache, Linux) that uses photoshop's JPEG writing algorithm?
Original Image created by photoshop:
Image that results from simply read / save 100% in GD2.
FYI, I also opened the image using IrfanView, and saved it at 100%, the results are a near match to what I got from GD2.
