Creating images with javascript

August 24th, 2007

If you feel like being a little bit silly today, you might check out some code I wrote to generate BMP images right in the browser, using javascript. For maximum compatibility, I'm using the v3 header and uncompressed 24-bit color.

All mine does so far is generate a quasi-random bitmap. The same technique could be used to generate very small rounded-corner images and other progressive enhancements. Perhaps some other file formats might be interesting to play with as well. Excel spreadsheets, perhaps? I don't have much interest in continuing work on javascript-based file production, but I'd love to see other people take this idea for a spin.
