WinBackupToScr |
Function (ROM Call 0x3) |
Shows a current backup screen.
If the window pointed to by w is active, WinBackupToScreen copies the current backup
screen (duplicate screen) to the real screen (more precise, to the client area of the
window), else does nothing. This routine assumes that a window is opened with the
WF_DUP_SCR flag (see WinOpen). Then, all output
to that window is saved in a backup screen image (allocated in the heap). So, this routine
copies the contents of that image to the real screen.
Uses: BitmapPut
