Environment: VC6 (earlier probably ok too), Win2K/95/98

This class extends the MFC CPictureHolder class to include




Simply include the .h and .cpp into your project and use it as you would CPictureHolder.

You can also use this instead of the CBitmap class (but with code changes, of course).

And remember that CPictureHolder has a Render method to draw pictures, and it support transparency for GIF's etc.

I built this with various versions of VC6. I don't see why it wouldn't work on other recent versions.

NOTE 1: I would usually have made many of these member functions const. However, CPictureHolder doesn't use any consts, and so I would have to have done lots of (potentially unsafe) const casts in my code.

NOTE 2: Chensu says that OldLoadPicture/IPicture has problems with palettes. I haven't looked at his code yet, but if so, I will (with his permission) update this code to include whatever fixes he added to better support palettes

NOTE 3: I haven't included support for icons in here. It would be trivial to add so I'll leave it as an excercise for the reader :-) ...
