I never noticed any lines or banding on my screen, so maybe it was fixed in the GD library or present only in certain situations.

If you have something isolated on pure white (FFFFFF), then resized (by GD) images, like thumbnail, preview and every image sent to buyer (below large, which is not touched by GD), have horizontal lines containing FDFDFD pixels. It is almost invisible and easily removable. Other images, with no white background, maybe are affected too, but color change is below noise level.

Andrzej, thanks for explaining it.

Back to my previous question:
If my host supports ImageMagick only in the binary form (not as PHP extension), is there anything I can do to make Symbio template work with that binary program?

The code checks to see if the ImageMagick PHP extension is loaded.  If it finds that it is loaded, then it uses it.  If it doesn't see that it is loaded, then it uses GD.

You would have to change the code to make it work differently.

I think les is asking how he can change that code to make it work.
