Welcome to JavaRanch, Luc! If you're not already familiar with them, you may want to take a look at The 2D Graphics Trail of Sun's Java Tutorial and The J2SE API Documentation. Otherwise, you mentioned that you are having some problems. So, what are they exactly? Feel free to post relavent example code (just be sure to surround the code with the [code] and [/code] UBB Tags). Good luck and I hope to see you 'round the Ranch!
