[FlagsAttribute()] public enum class RasterMemoryFlags : public System.Enum, System.IComparable, System.IConvertible, System.IFormattable
| Value | Member | Description |
|---|---|---|
| 0x0000 | None | No flags. |
| 0x0001 | Conventional | Use conventional memory. |
| 0x0002 | User | Creates an image where the user maintains the data pointer.
Some image processing commands, such as Leadtools.ImageProcessing.RotateCommand and Leadtools.ImageProcessing.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. |
| 0x0004 | Tiled | Creates an image where the data pointers are maintained in tiles, useful for very large images. |
| 0x0008 | NoTiled | Do not allow tiled images. |
| 0x0080 | Disk | 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. |
| 0x0100 | NoDisk | Do not swap to disk using LEAD virtual memory. Windows virtual memory is not affected. |
| 0x0200 | Compressed | (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. |
| 0x0400 | SuperCompressed | (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. |
| 0x0800 | WriteableBitmap | (Document/Medical only) Use a Silverlight WriteableBitmap for memory storage. This option works only for 32-bit images.. |
