It can do anti-alias smoothing, smooth scaling, spline curves, alpha channel. It has the usual paint functions. Its main weakness is converting high colour to 256 colours. It does not know how to do the octree algorithm to select the optimal set of colours. Once you place something it is fixed. It does not maintain the entire image as a set of movable vector objects. The undo tends to jump back a great many steps. You get a great improvement in your icons just by loading them, converting to 32-bit alpha channel, and clicking smooth, and perhaps adding a drop shadow.

It is missing a useful simple feature, the ability resize to 50%. You must calculate the image size width and height yourself. To use the smoothing function, you must turn on high-colour and alpha-channel. It does not seem to have a way to reduce the colour depth and maintain alpha-channel transparency. The more I used it, the more I liked it. I own a copy. The company is headquartered nearby in Vancouver, BC Canada.

The program now has a big brother called IconLover that has extended editing features, and the ability to etract icons and manage icon libraries.

IconXP costs $30.00 USD . Icon-Lover costs $50.00 USD .
