virtual L_INT LAnnotation::GetRgnHandle(phRgn, pXForm=NULL)
HRGN * phRgn; |
address of the variable to be updated |
pRGNXFORM pXForm; |
pointer to a coordinate translation structure |
Creates a region from the specified annotation object and retrieves a handle to that region.
Parameter |
Description |
phRgn |
Address of the variable to be updated with the handle to the region, if the function is successful. |
pXForm |
Pointer to an RGNXFORM structure that LEADTOOLS uses to translate between display coordinates and bitmap coordinates. |
|
If you specify NULL in this parameter, the scalar fields default to 1, the offsets default to 0, and the view perspective defaults to TOP_LEFT. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
You can create regions from the following annotation objects:
When working with the RGNXFORM structure in this function, consider the following:
the annotations are always TOP_LEFT.
the bitmap is missing, so the bitmap rectangle is replaced by the object rectangle.
it is easier to work with this function using TOP_LEFT as the ViewPerspective.
