Creating images with javascript
Automated disclaimer: This post was written more than 15 years ago and I may not have looked at it since.
Older posts may not align with who I am today and how I would think or write, and may have been written in reaction to a cultural context that no longer applies. Some of my high school or college posts are just embarrassing. However, I have left them public because I believe in keeping old web pages alive—and it's interesting to see how I've changed.
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.
