virtual L_INT LBitmapBase::Allocate(nMemoryType=TYPE_CONV)
type of memory
Allocates memory for the bitmap data.
|nMemoryType||The type of memory to be used when allocating memory for the bitmap data. Possible values are:|
|TYPE_CONV||[0x0001] Use conventional memory if the image will fit, otherwise swap to disk.|
|TYPE_USER||[0x0002] Create a bitmap where the user maintains the data pointer.|
|TYPE_TILED||[0x0004] Create tiled bitmaps.|
|TYPE_NOTILED||[0x0008] Do not create tiled bitmaps, even if the conventional memory has failed.|
|TYPE_DISK||[0x0080] Do not use conventional memory. Swap to disk only.|
|TYPE_NODISK||[0x0100] Do not swap to disk using LEAD's virtual memory. Windows virtual memory is not affected.|
|TYPE_COMPRESSED||[0x0200] (Document/Medical only) Allocate an RLE-compressed bitmap. This flag can be used with TYPE_CONV or TYPE_NODISK. For more information, refer to Speeding Up 1-Bit Documents.|
|TYPE_SUPERCOMPRESSED||[0x0400] (Document/Medical only) Keep images compressed in memory. This option causes slow access, but very low memory usage. This option is available only for 1-bit, 8-bit grayscale and 24-bit images.|
The function was successful.
An error occurred. Refer to Return Codes.
The amount of memory allocated depends on the size of the image indicated in the internal bitmap handle (Width, Height, and BitsPerPixel). LBitmapBase::Initialize must be called prior to calling this function.
This is a low-level function that is used only when you create a bitmap from scratch using LBitmapBase::Initialize. Normally, the functions that load or create a bitmap allocate the required memory for you. (In that case, calling Allocate() causes your application to lose memory.)
