I have coded a small dll library for working with offscreen surfaces. Everything is coded from scratch, including the surface types, to make it as a fast as possible. The databuffer for each surface is in a top-down, dib compatible format, supporting 8,16,24 & 32 bpp. Is there any way for me to load a raw memory buffer into a TBitmap or any hDC from memory? Can i get a pointer to a hdc databuffer somewhere? At this point, i am using move() to copy each rasterline into a TBitmap, but that is a bit slow (but still workable). If would be faster to use one big Move() instead. Any help is welcome!
