Bitmap and Caching Properties of IMsRdpClientAdvancedSettings (Windows CE 5.0)
You can set and retrieve properties related to the size of bitmap cache files, persistent bitmap caching, and whether bitmap shadows should be used. The following table shows the properties you can set and retrieve.
| Property | Description |
|---|---|
| BitmapCacheSize | Size, in KB, of the bitmap cache file used for 8-bits-per-pixel bitmaps. The maximum value is 32000. |
| BitmapPersistence | Value that specifies whether persistent bitmap caching should be used. A nonzero value enables this property and zero disables it. Persistent caching can improve performance but requires additional disk space. |
| BitmapVirtualCacheSize | Size, in KB, of the persistent bitmap cache file to use for 8-bits-per-pixel. The maximum size for all virtual cache files is 128KB. |
| BitmapVirtualCache16BppSize | Size, in KB, of the persistent bitmap cache file to use for 16-bits-per-pixel high-color settings. The maximum size for all virtual cache files is 128KB. |
| BitmapVirtualCache24BppSize | Size, in KB, of the persistent bitmap cache file to use for the 24-bits-per-pixel high-color setting. The maximum size for all virtual cache files is 128KB. |
| NumBitmapCaches | Number of bitmap caches to use. The default value is 3, which results in the best performance. |
| PersistCacheDirectory | Path to the directory for storage of bitmap cache files. This property is write-only. |
| ScaleBitmapCachesByBPP | Specifies whether the size of bitmap caches should be scaled by bit depth (bits per pixel). A nonzero value enables this property and zero disables it. It is recommended that you leave this property at its default value, which is enabled. |
| ShadowBitmap | Specifies whether shadow bitmaps should be used. Shadowing allows a user to remotely monitor the on-screen operation of another user. A nonzero value enables this property, zero disables it. Disabling this property typically improves performance but can result in artifacts when painting screens. |
