Handles each bump or nick found by L_SmoothBitmap.
Flag that indicates whether to remove bumps or fill in nicks. Possible values are:
|SMOOTH_BUMP||Remove a bump.|
|SMOOTH_NICK||Fill in a nick.|
The starting row of the bump or nick. The rows are zero-based.
The starting column of the bump or nick. The columns are zero-based.
Length (in pixels) of the bump or nick.
Flag that indicates whether the element being smoothed is vertical or horizontal. Possible values are:
|SMOOTH_HORIZONTAL_ELEMENT||A horizontal bump or nick|
|SMOOTH_VERTICAL_ELEMENT||A vertical bump or nick|
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_SmoothBitmap).
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 bump or nick.|
|SUCCESS_NOREMOVE||Do not remove the bump or nick.|
|Otherwise||An error occurred. Refer to Return Codes.|
The callback is called for each bump and nick found. Return SUCCESS_REMOVE to have the bump or nick removed. Return SUCCESS_NOREMOVE to leave the bump or nick unchanged. Pass any other value to abort. This value will be the return value of the L_SmoothBitmap(). If flags SMOOTH_IMAGE_UNCHANGED and SMOOTH_SINGLE_REGION are being used, then the return value of the callback affects only the internal single region that contains all the changes.
For an example, refer to L_SmoothBitmap.
