I posted about ajaxWrite last week, and how the creators of Linspire are releasing a new ajax based webapp each week . This week's is a vector drawing program called ajaxSketch. For those who have no Idea what I'm talking about, a vector drawing program is a program which allows you to draw using lines and shapes, instead of pixels ( see the post about how bitmaps work). This is advantageous because it allows you to scale the images with very little loss in quality, while still keeping the file sizes under control. Go try out ajaxSketch (requires >= Firefox 1.5), but if you want something more powerful, and can't afford Microsoft Visio (very useful program), try OpenOffice, InkScape, Sodipodi or QCad, although I don't like any of them very much (Openoffice is a great word processor). Most Flash animations/drawings are also vector based.
If you have a very fast computer and lots of RAM, you can try to convert (trace) a bitmap into a vector image using AutoTrace, but I find that it doesn't work too well, and the RAM requirements are huge. There aren't many reasons to want to do this anyway, but I mention it because there are a few (Computerized Embroidery software uses this process to Embroider pictures).
Enjoy your Sunday afternoon, back to my Homework ;-(
