#include "ltwrappr.h"
virtual L_INT LAnnotation::GetArea(puCount)
L_SIZE_T * puCount; |
/* address of a variable to be updated */ |
Gets the pixel count of the specified annotation object.
Parameter |
Description |
puCount |
Address of the variable to be updated with the pixel count. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The pixel count is the number of pixels contained in a region extracted from the annotation object, without resizing. It is equivalent to calling LAnnotation::GetRgnHandle with pRgnXForm set to NULL and then getting a pixel count of the resulting region.
