Can I create a huge bitmap/texture (5000x3000 pixels @ ARGB), draw on it and then display it? (eg. TPixMap?)
I know that video card textures are usually limited to 2096x2096 but I'm hoping to store my huge texture/bitmap in system memory and then upload only parts of it to the video card.
The keys parts of what I'm trying to do are:
1) Storing a huge bitmap (ARGB format)
2) Drawing on it (changing alpha values mostly)
3) Display part of the bitmap to the screen
Every so-often I will need to change the huge bitmap (alpha values).
Thanks for any help!
