- It's just like a Mac! Well, sort of.
- Lock and load. Er, load and lock.
bitmapH = DmGet1Resource( 'Tbmp', TerrainBitmap );
bitmapP = ( BitmapPtr )MemHandleLock( bitmapH );
- Oh yeah, don't forget error checking. This example is diagnostic only. But lots of calls return NULL for objects so it's an easy check.
if ( bitmapP == NULL )
ErrNonFatalDisplay( "Terrain bitmap is NULL" );
- Draw the bitmap to the current draw window. Saw this in the previous slide.
WinSetDrawWindow( gOffscreenTerrainWindow );
WinDrawBitmap( bitmapP, 0, 0 );
- Unlock and release.
MemHandleUnlock( bitmapH );
DmReleaseResource( bitmapH );
