Some suggestion on Very Large Bitmap Experiment.

From win API Help:

HBITMAP CreateDIBSection(
    HDC hdc, // handle to device context
    CONST BITMAPINFO *pbmi, // pointer to structure containing bitmap
size, format, and color data
    UINT iUsage, // color data type indicator: RGB values or palette
indices
    VOID *ppvBits, // pointer to variable to receive a pointer to the
bitmap's bit values
    HANDLE hSection, // optional handle to a file mapping object
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ using this I
successfully got 1GB image 32700x32700x8bit
    DWORD dwOffset // offset to the bitmap bit values within the file
mapping object
   );
WIN NT 4.0 ws + sp4, RAM 128, Maxtox G400 64. P III 400
Time: as much as coping 1GB data on HD.
Used home-fixed TBitmap in Delphi5.


So, no meter how big is your RAM, main thing is free space on hard
drive.
