How do i resize bitmap so that it will have more (or less) pixels (not =
stretching bitmap). Example: now it has 100x100 pixels, i want it to =
have 200x200 pixels. Do i have to recreate new bitmap? If yes, do i have =
to delete old bitmap with DeleteObject(), or will it delete itself =
automatically, if i assign it to same pointer.
Do i use DeleteObject() for 1 pointer just once at the end of program?
Example:
=20
atom hBitmap --hBitmap is pointer
hBitmap=3DCreateBitmap(100,100) --create first bitmap
DeleteObject(hBitmap) --DO I HAVE TO DO THIS?
hBitmap=3DCreateBitmap(200,200) --create second bitmap, assign it to the =
same pointer
