Script

I ain't no good at python yet, but here's a script that might let you automagically convert youse's pngs into xbms. I couldn't get this to work on the olpc, but it should work in most python environments with pygame installed.

It will produce files of the form cursorRC.xbm and maskRC.xbm where R is the (0 indexed) row number of your desired cursor, and C is the column number. You will probably want to convert those names to something legible before using the cursors. Anyone is free to improve this script (I am sure there are plenty of ways to do that) or otherwise do what you want with it, etc.

Help!

Hi! I'm working in a project for my university about an application for sugar and I really really need the SVG or any kind of vector file of "Standard Sugar Cursors", like this one: http://wiki.laptop.org/go/Image:Sugar-00.png I need it to use in Adobe Illustrator. Does anyone know where I can get it? I looked everywhere already!! Thanks! Lu
