A rectangle structure used to specify the area where the object exists.
A two dimensional array represents the information about the object shape.
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.
