Bit depth weirdness


Recommended Posts

When saving a PNG file with the bit depth set to auto detect, it sometimes incorrectly guesses 8 bit instead of 24 or 32, which somehow creates an image which looks fine in windows photo viewer and PDN itself and on thumbnails, but in other programs (or PNG file reader APIs) it messes up wildly and cannot be colorized in some situations. Here are 2 screenshots from Minecraft, one with the issue (taken a while ago) and one which I took today after realizing what had happened and saving in 32 bit depth.





More info:

Windows 7 SP1 64Bit

Paint.NET 4.0.3

.NET Framework 4.5.1

Well, it certainly auto-chooses 8bit when theres less than 256 colors used in the image. That would be a correct decision. If it looks fine in other programs but just not in minecraft, then that's pretty much proof that paint.net is working correctly and it's minecraft with the problem.
