I have sent it to you. Let me know if this works. The function you
want is:
void DrawBitmap(UInt16 x, UInt16 y, UInt16 id)
{
MemHandle h;
BitmapPtr p;
h = DmGet1Resource(bitmapRsc, id);
if (h != NULL) {
p = (BitmapPtr) MemHandleLock(h);
WinDrawBitmap(p, x, y);
MemHandleUnlock(h);
DmReleaseResource(h);
}
}
Note that this function will pull a bitmap from the program's *.prc file
and draw it a coordinates x, y. You need to know the id of the bitmap.
It should be the resoruce id, the number found next to the bitmap (or
bitmap family) in Constructor. I do not store the resource bitmap,
since it is already in a resource. I simply draw it to the screen.
BTW you need a colored simulator, emulator, or palm to run this, else
change the code that checks for the colored device feature in the
AppStart() function. Hope this helps and you can code this alright.
I hope the helps. The algorithm for reading a windows bitmap from the
SD card or a *.pdb is different. You will want different code for that.
I had enough trouble getting this working, but I have code in another
program that will capture from the screen and save the result to a
windows bitmap. The problem is, the conversion processing is done in
hotsync, not on the handheld. I do not have that code at home, so it
may take a few days to get it.
As long as the bitmap is created in the prc file in constructor, the
above code will work. If not, email me back for something different.
The other code is not easy and I recall having crashed the poor little
m515 I ran it on (over and over) while doing it.
