I'm using KImageMapEditor on Linux (Ubuntu) to create an image map. The shapes in the image are a little complex so I'm using the freehand tool to draw them. However, this is really the same as the polygon tool so the shapes have ended up with a lot of points, which has made the HTML pretty huge.
Does anyone know of a way to reduce the complexity of the shapes, like "smoothing out" the lines?
I should also mention the reason I want the shapes to be fairly accurate is because I'm intending to do something like this, where each shape is highlighted on mouseover: http://davidlynch.org/js/maphilight/docs/demo_usa.html
Since users aren't going to click to the pixel, give them some leeway and create a "sloppy" map which roughly outlines each shape instead of clinging to the actual pixel outline.
This is in the same way as you don't expect a click on a link to fail just because you click on the background which shines through the text. You expect the bounding box of the text to act as the click-able area instead of the "black pixels".
