I have run into the same problem with my open source image editor, ImagePlay.
For downsizing, the easy way to solve the "jaggies" problem is to blur the image slightly before reducing the size. But I think a better looking way is to calculate the pixel mixing yourself, it will certainly be slower than just using g.drawpicture to do the scaling though. For increasing the size, the easiest way is to blur the image after resize. A 1 pixel blur for a 2x resize tends to take the jaggies off without being too blurry, in my opinion. You can get the source code to ImagePlay at http://imageplay.sourceforge.net/ (It contains a module chock full of effects such as Resize and Blur which you are free tp use in your own programs.)
