Create a new instance of the CacheCompactor interface class.
The type of compaction algorithm used depends on values from the configuration: the SlideSorter/PreviewCache/CompactionPolicy property of the Impress.xcs file currently supports the values "None" and "Compress". With the later the CompressionPolicy property is evaluated which implementation of the BitmapCompress interface class to use as bitmap compressor.
- Parameters
-
| rCache | The bitmap cache on which to operate. |
| nMaximalCacheSize | The total number of bytes the off-screen bitmaps in the cache may have. When the Run() method is (indirectly) called the compactor tries to reduce that summed size of off-screen bitmaps under this number. However, it is not guaranteed that this works in all cases. |
