Copy the negated bitmap to the onscreen window
Listing 4 begins by copying the negated bitmap to the bottom of the onscreen window as shown in Figure 1.
Then Listing 4 blocks and waits for the user to press a key, at which time it destroys the memory bitmap and terminates the program.
Listing 4. Copy the negated bitmap to the onscreen window.
//Copy the modified bitmap to the onscreen window // immediately below the original image. blit(picA, screen, 0,0,0,330,324,330); //Block and wait until the user presses a key. readkey(); //Destroy bitmaps to avoid memory leaks. destroy_bitmap(picA); return 0;//Return 0 to indicate a successful run. }//end main function END_OF_MAIN()
