#include "l_bitmap.h"

L_INT pEXT_CALLBACK Your Function(uBumpOrNick, iStartRow, iStartCol, iLength, uHorV, pUserData)

L_UINT uBumpOrNick;	flag
L_INT iStartRow;	starting row
L_INT iStartCol;	starting column
L_INT iLength;	length
L_UINT uHorV;	flag
L_VOID *pUserData;	pointer to additional parameters

Handles each bump or nick found by L_SmoothBitmap.

Parameter	Description
uBumpOrNick	Flag that indicates whether to remove bumps or fill in nicks. Possible values are:
	Value	Meaning
	SMOOTH_NONE	Do nothing.
	SMOOTH_BUMP	Remove a bump.
	SMOOTH_NICK	Fill in a nick.
iStartRow	The starting row of the bump or nick. The rows are zero-based.
iStartCol	The starting column of the bump or nick. The columns are zero-based.
iLength	Length (in pixels) of the bump or nick.
uHorV	Flag that indicates whether the element being smoothed is vertical or horizontal. Possible values are:

	Value	Meaning
	SMOOTH_HORIZONTAL_ELEMENT	A horizontal bump or nick
	SMOOTH_VERTICAL_ELEMENT	A vertical bump or nick
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_SmoothBitmap).
	Keep in mind that this is a void pointer, which must be cast to the appropriate data type within your callback function.

Returns

SUCCESS_REMOVE	Remove the bump or nick.
SUCCESS_NOREMOVE	Do not remove the bump or nick.
Otherwise	An error occurred. Refer to Return Codes.

Comments

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.
