What's New on MDC

Just thought I’d point out some new content appearing on the Mozilla Developer Center (MDC).

• Saving Canvas to a File: Given a canvas element and a destinstion file path, this code snippet saves the contents of the canvas to a PNG file. The code could easily be tweaked to become a general purpose “download to file” instead of only handling canvas elements.
• XUL Control Guide: This is a handy quick guide to the various XUL control elements. In addition to a picture of the control, there are also links to reference and tutorial information.
• Observing the Download Manager: This snippet shows how you can observe the various notifications of the download manager.
• Troubleshooting XPCOM Registration: When component registration fails its currently very difficult to figure out the cause. This article steps through a few troubleshooting tips you can use to find the problem. We hope to get better tracing and debugging of component registration failures in Firefox 3.
