Parameter |
Description |
rcRect |
A rectangle structure used to specify the area where the object exists. |
pObject |
A two dimensional array represents the information about the object shape. |
pUserData |
A void pointer that you can use to access a variable or structure containing data that your callback function needs. This gives you a way to receive data indirectly from the function that uses this callback function. (This is the same pointer that you pass in the pUserData parameter of L_ObjectCounter function). |
|
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
This function is used to control a part of the image where the object was found.
L_ObjectCounter supports only 1-bit images. The callback should reflect that if there are any operations on the image itself.
