Handles each dot found by L_DotRemoveBitmap.
Windows region representing the dot to be removed. It is the programmer's responsibility to delete this region (using DeleteObject()) when it is no longer needed.
Pointer to a RECT structure that contains the bounding rectangle of the dot being processed.
Total number of white pixels in the dot being processed.
Total number of black pixels in the dot being processed.
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_DotRemoveBitmap.)
Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.
|SUCCESS_REMOVE||Remove the dot.|
|SUCCESS_NOREMOVE||Do not remove the dot.|
|Otherwise||An error occurred. Refer to Return Codes.|
The callback is called once for each dot, speck, or blob that is detected Return SUCCESS_REMOVE to have the dot removed. Return SUCCESS_NOREMOVE to leave the dot unchanged. Pass any other value to abort. This value will be the return value of the L_DotRemoveBitmap(). If DOT_IMAGE_UNCHANGED and DOT_SINGLE_REGION are being used, then the return value of the callback affects only the internal single region that contains all the changes.
