QA: How can I get bitmap bits?
July 02, 2001.
I loaded bitmap using LoadBitmap function. Now I want to read bitmap
bits (color of each point). How can I do it? I have looked at GetDIBits

Loading Images with undocumented API in PPC 2002
13 Aug 2002.
Loading images under windows can always be a painful process, especially if the image formats are like JPEG, GIF or PNG. There's always the Imgdecmp library, that does a good job, but its also a bit of a bother with the documentation being so thin and all that. The other day I was trying to load a bitmap from my device using LoadImage, but somehow I kept getting the dreaded "The handle is invalid" error. So I did a search on the MFC code that ships with the PPC SDK in hope of finding a piece of code that will help me solve the puzzle.

Display PNG, JPG, etc on PocketPC
23 Sep 2002.
In doing quite a bit of work with a PocketPC home automation client, I needed a way to display user-defined images in the device.
I found some very good and useful code out there in CodeProject and was able to combine them (with some modifications and enhancements) into group of very useful libraries.
I won't go into too many details, as I've basically taken Chris Maunder's DibSectionLite and added methods to load using Davide Pizzolato's CXImage classes. You can find their original libraries and documentation on this site. No point in replicating it here.
