Can GD sharpen images??
Does anyone know of a way to sharpen images using gd...? or if it can be done?

Yeah.. convolution filtering.. I wrote an article about it for my site:

Its complicated, and that code isn't particularly flexible unfortunately. But it works. Sort of.
The code includes filters for gausian blur, smoothing, sharpening, and a bunch of edge detection routinues.
