Detailed Description

Class IBitmapPager
Description:
This class exposes parameters to the Bitmap Pager. This pager reduces memory footprint by swapping bitmap data to and from disk, keeping the memory usage of bitmaps within a certain percentage of total available memory. Internally, all bitmaps are partitioned into separately allocated tiles, but tiles are only swapped to disk when the pager is enabled. For performance reasons the tile size varies dynamically for each bitmap, but is typically around 1-4 megabytes. Bitmaps smaller than one tile are not eligible for paging, and are held in memory at all times.

Member Function Documentation

◆ DECLARE_DESCRIPTOR()

DECLARE_DESCRIPTOR ( IBitmapPager  )

◆ IsPagerEnabled()

virtual BOOL IsPagerEnabled ( )
pure virtual

Returns whether bitmap paging is enabled.

Internally, all bitmaps are partitioned into separately allocated tiles. With paging is enabled, bitmap tiles are swapped to disk, keeping total bitmap usage below the memory limit.

◆ SetPagerEnabled()

virtual void SetPagerEnabled ( BOOL  b)
pure virtual

Enables or disables bitmap paging.

Internally, all bitmaps are partitioned into separately allocated tiles. Passing TRUE immediately swaps bitmap tiles from memory to disk, reducing total bitmap usage below the memory limit. Passing FALSE does not immediately swap bitmap tiles from disk to memory, but no further tiles are swapped to disk while paging is disabled.

◆ GetMemoryLimit()

virtual size_t GetMemoryLimit ( )
pure virtual

Returns the current memory limit physical value, in bytes.

This is the value used internally in deciding whether to swap bitmap tiles to disk. The value is not live, but is calculated from the memory limit percentage at specific times, during file load, file reset, render begin and render end.

◆ GetMemoryUsedForPager()

virtual size_t GetMemoryUsedForPager ( )
pure virtual

Returns the total memory usage of bitmap tiles (excluding tiles on disk), in bytes.

◆ GetMemoryPadding()

virtual size_t GetMemoryPadding ( )
pure virtual

Returns the current memory padding physical value, in bytes.

◆ GetMemoryAvailablePadded()

virtual size_t GetMemoryAvailablePadded ( )
pure virtual

Returns the amount of available memory for the entire application, after padding, in bytes.

◆ GetMemoryTotalForPager()

virtual LONGLONG GetMemoryTotalForPager ( )
pure virtual

Returns the total memory and disk usage of bitmap tiles, in bytes.

May exceed 2GB.
