Just thought I'd put this somewhere in the forums so it might show up in search results. I have a UCPen (UGEE) tablet (Taiwanese company). Pressure sensitivity does work in Paint.NET in Vista after: Installing the Vista drivers from the website and (important) enabling "Support Tablet PC Feature" The second step is what got me; otherwise, it can't use Tablet PC features (obviously).

usedHONDA's results are misleading, showing at one point that HD Photo had better lossless compression than PNG. I would be surprised if anything could beat PNG, but I am working with incomplete information here. Both of his PNG images have an extra alpha channel in there. There's obviously there is no alpha to speak of, so that's superfluous data. Using optiPNG, which removed the alpha (and might've used better compression parameters), the first image (pnglogo.png) became 98427 bytes (96 kiB), better than HD Photo. The second image (hdlogo.png) is 136271 bytes (133 kiB) when optimized. It was already smaller than HD Photo. I don't know much about HD Photo. Let me know if the HD Photo export also includes extraneous image data.

What is currently supported?

What is the status of metadata support (schemes, filetypes) in paint.net? I am dependent on metadata for interoperability - Desktop search, consistent descriptions, organization, archival information, etc. I would like to see (if it hasn't been done already) EXIF, IPTC, and the newer XMP supported in PDN, JPG, TIFF, and PNG (although you might want to wait until Adobe gets PNG all hashed out).
