Members

ValueMemberDescription
0x00000000None No flags.
0x00000001Conventional Use conventional memory.
0x00000002User Creates an image where the user maintains the data pointer. Some image processing commands, such as RotateCommand and ColorResolutionCommand, need to re-allocate the image data. If you create a bitmap with RasterMemoryFlags.User, and pass it to these command, they will change the bitmap to RasterMemoryFlags.Conventional and re-allocate memory. Your original memory will no longer be used.
0x00000004Tiled Creates an image where the data pointers are maintained in tiles, useful for very large images.
0x00000008NoTiled Do not allow tiled images.
0x00000080Disk Do not use managed memory. Swap to disk only. If the image is allocated as Disk, then the image should not be used in multiple threads.
0x00000100NoDisk Do not swap to disk using LEAD virtual memory. Windows virtual memory is not affected.
0x00000200Compressed (Document/Medical only) Allocate an RLE-compressed image. You can use this flag with None or NoDisk. For more information, refer to Speeding Up 1-Bit Documents.
0x00000400SuperCompressed (Document/Medical only) Allocate a CMP-compressed image. You can use this flag with None or NoDisk. The compression used for 24-bit and 8-bit images is lossy, which means multiple changes to the image can produce some visual loss.
0x00000800WriteableBitmap (Document/Medical only) Use a Silverlight WriteableBitmap for memory storage.
This option works only for 32-bit images..
Remarks

For more information, refer to Memory Storage Types for Images. Use only RasterMemoryFlags.Conventional or RasterMemoryFlags.Disk when setting defaults.
