SetMemoryThresholds method (Main Control)
|
Builder Syntax |
int SetMemoryThresholds(int nTiledThreshold, int nMaxConvSize, int nTileSize, int nConvTiles, int nConvBuffers, unsigned uFlags); |
|
Delphi Syntax |
Function SetMemoryThresholds(nTiledThreshold: L_INT; nMaxConvSize: L_INT; nTileSize: L_INT; nConvTiles: L_INT; nConvBuffers: L_INT; uFlags: L_UINT ): L_INT; |

Refer to Memory Storage Types for Bitmaps |
Remarks
Sets the memory restrictions for allocating bitmaps.
These are global settings and apply to the current thread. They will apply to bitmaps created in this thread after this method is called.
As an example, suppose an image needs 150 tiles and
nConvTiles = -30
nConvBuffers = -50
In this case, there are 30% conventional memory tiles (30% of 150 = 45) and 70% disk tiles (70% of 150 = 105).
For the 105 disk tiles, there are enough cache buffers for 50% of them.
50% of 105 = 52
Therefore, 52 memory buffers will be used to cache the 105 disk tiles.
