Or How to get the size of a BitmapPtr under OS 5....
In one of our apps, we do the following:
Err error = 0;
WinHandle saveWinH = NULL;
BitmapType *bp;
saveWinH = WinSaveBits(bounds, &error);
bp = WinGetBitmap(saveWinH);
// Validate Image Offset...
imageSize = MemPtrSize(bp);
This works well, actually, on all 3.5/4.x devices and to-date have
experience no ill effects. However in OS/5 the Simulator blows up big time
at the MemPtrSize() function. If there's a better way to get the size of
the bitmap, I'm open to it.
On a side note, has anyone published anything that discusses how programs
that scribble on the screen can capture the screen or portions from in
PalmOS 5 and what we'll need to do to make that compatible with earlier
versions? And backwards? I'd like to give my users the ability to use
sketches they've created in prior devices, but for now have to 'turn off'
that functionality.
