BITMAP

************* PLEASE BE PATIENT TO READ THIS WHOLE STUFF**************

We are Developing a Airfield lighting control system software which consist of a Main 17 inch Air Traffic Tower Display Screen and many other displays.The Main Display should show The Current ACTIVE Runways,taxiways and corresponding lighting systems .We have About 300 individual BITMAP Images To display on The screen .Sinc It would take a Large amount of Disk Space
we would like to

1)Is there any way to fill certain portions inside a BITMAP using flood -fill or any other similar programs?(so that a Single BITMAP could be used)

You always can draw into a bitmap. You have to receive a pointer to the bitmap bits and then you can change the bits. But the original bitmap is overwritten. Another way is to copy the original bitmap to a memory device contect and then make additional drawing into the device contect and finaly blit the memory DC to the screen. If this is too slow you can use directx.

Hope this helps
