virtual L_INT LBitmap::GetOverlayAttributes(nIndex, pOverlayAttributes, uStructSize, uFlags)
L_INT nIndex; |
the overlay index |
pOVERLAYATTRIBUTES pOverlayAttributes; |
pointer to the overlay attributes structure to be updated |
L_UINT uStructSize; |
the size of the OVERLAYATTRIBUTES structure |
L_UINT uFlags; |
flags that determine which attributes should be retrieved |
Gets one or more overlay attributes for a certain index.
Parameter | Description | |
nIndex | The index of the overlay whose attributes we want to retrieve. This index is zero-based. | |
pOverlayAttributes | Structure which will be filled with the overlay attributes. | |
uStructSize | Size of the OVERLAYATTRIBUTES structure pointed to by pOverlayAttributes - pass sizeof(OVERLAYATTRIBUTES). | |
uFlags | Flags that determine which attributes to retrieve. You can combine values by using a bitwise OR ( | ). Possible values are: | |
Value | Meaning | |
OVERLAYATTRIBUTES_ORIGIN | [0x0001] Retrieve the top-left position. pOverlayAttributes ->ptOrigin will be updated with the top-left offset. | |
OVERLAYATTRIBUTES_COLOR | [0x0002] Retrieve the color. pOverlayAttributes ->crColor will be updated with the color. | |
OVERLAYATTRIBUTES_FLAGS | [0x0004] Retrieve the flags. pOverlayAttributes ->uFlags will be updated with the flags. | |
OVERLAYATTRIBUTES_BITINDEX | [0x0008] Retrieve the corresponding bitplane position. pOverlayAttributes-> uBitPosition will be updated with the bitplane index. | |
OVERLAYATTRIBUTES_DICOM | [0x0010] Retrieve the DICOM-related attributes, this includes: | |
pOverlayAttributes->uRows, | ||
pOverlayAttributes->uColumns, | ||
pOverlayAttributes->szType, | ||
pOverlayAttributes->uBitsAllocated, | ||
pOverlayAttributes->szDescription, | ||
pOverlayAttributes->szSubtype, | ||
pOverlayAttributes->szLabel, | ||
pOverlayAttributes->nROIArea, | ||
pOverlayAttributes->fROIMean, | ||
pOverlayAttributes->fROIStandardDeviation, | ||
pOverlayAttributes->nNumFramesInOverlay, | ||
pOverlayAttributes->uImageFrameOrigin, | ||
pOverlayAttributes->szActivationLayer |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
One or more overlay attributes will be retrieved. Their values will be stored in the structure pointed by pOverlayAttributes. pOverlayAttributes ->uStructSize will be set to the value of the parameter uStructSize. Only uStructSize and the values retrieved by the function will be set. The other values are left unchanged.
