Poor image quality
I'm struggling with image quality.
Images uploaded via Perch with a uniform colour background (e.g. illustrations, logos) are appearing with lightly flecked backgrounds. I'm specifying quality="100" and sharpen="0" in an attempt to stop Perch processing the images too much (is this right?). The only processing I'm asking Perch to do is a resize.
JPGs are bad, but PNGs containing transparencies contain very unsightly artifacts - so much so that they are unusable.
Plus, PNGs are often cropped a few pixels too short. Frustrating!!!
It only seems to occur when asking Perch to resize images. As a work-around I'm cropping images manually and not asking Perch to do anything - fine for me, but not great for my client!
I've tried on sites running on both Windows and Unix and both have the same trouble.
Can you offer any advice, please? Thanks.
