Properties | |
| readonly VpatLayout | XVpatLayout [get] |
| Increment layout of the x VPAT. | |
| readonly VpatLayout | YVpatLayout [get] |
| Increment layout of the y VPAT. | |
| VpatLayout | VpatLayout [get] |
| Combined VPAT layout. If x or y VPAT layout is confuse, the combined layout will also be confuse. If x or y VPAT layout is linear, the combined layout will also be linear. If x and y VPAT layout is linear with data type, the combined layout will be linear with data type. | |
| readonly VpatRotation | Rotation [get] |
| Guesses the rotation of this VPAT. | |
| readonly IntPtrIndexer | XEntry [get] |
| X offset table. | |
| readonly IntPtrIndexer | YEntry [get] |
| Y offset table. | |
| readonly IntIndexer | IntXEntry [get] |
| X offset table. | |
| readonly IntIndexer | IntYEntry [get] |
| Y offset table. | |
| readonly LongIndexer | LongXEntry [get] |
| X offset table. | |
| readonly LongIndexer | LongYEntry [get] |
| Y offset table. | |
| readonly IntPtr | BasePtr [get] |
| VPAT base pointer. | |
| readonly IntPtr | VpatPtr [get] |
| Pointer to the native VPAT structure. | |
Virtual Pixel Access Table.
|
get |
VPAT base pointer.
Note that this is not necessarily a pointer to the first pixel in the image or the first pixel in the last line of the image, but merely a base pointer for calculating the address of a pixel using the x and y offset tables.
|
get |
X offset table.
VPAT access is returned as Int32 with this indexer. Note that it is only safe to use this indexer if your application is running as a 32 bit application.
|
get |
Y offset table.
VPAT access is returned as Int32 with this indexer. Note that it is only safe to use this indexer if your application is running as a 32 bit application.
|
get |
X offset table.
VPAT access is returned as Int64 with this indexer. This indexer is safe to use for 32 or 64 bit applications, but may increase processing time.
|
get |
Y offset table.
VPAT access is returned as Int64 with this indexer. This indexer is safe to use for 32 or 64 bit applications, but may increase processing time.
|
get |
Guesses the rotation of this VPAT.
The assumption about the underlying buffer is that it is positively linear (positive x- and y-increments). If this is not the case as with default windows bitmaps, the guess is plain wrong.
Entry of the VpatRotation enumeration.
|
get |
Pointer to the native VPAT structure.
This points to the first Entry and can be interpreted as Entry* in unsafe context.
|
get |
X offset table.
VPAT access is returned as IntPtr with this indexer, giving you the correct size of offsets for the platform you are running on, but making it necessary to properly convert the offsets when doing calculations.
|
get |
Y offset table.
VPAT access is returned as IntPtr with this indexer, giving you the correct size of offsets for the platform you are running on, but making it necessary to properly convert the offsets when doing calculations.
