Yes, it works. The scenario that I have is like this: I am trying to down-size a png image so I
open it with with-image-from-file copy resized image (copy-image old-image new-image ....) save it (write-image-to-file new-image-file-name :image new-image :compression-level 5)
In my case :compression-level doesn't change the size of the output image. Probably it happens because the original file that I am trying to re-size is already compressed to the maximum.
I fear I don't know enough about PNG compression to say anything profound here. I do suspect that it is a general GD issue rather than a cl-gd problem, so maybe asking on some GD support channel would be helpful? You'd propably need to supply the image in question to have someone comment on what compression you can expect. -Hans
