Function Documentation

IBinarizeCallback_Create()

IBinarizeCallback IBinarizeCallback_Create	(	PtrRemovePixelFn	ptrRemovePixelFn,
		idrs_exception *	pargException
	)

Creates a new IBinarizeCallback object.

Parameters

ptrRemovePixelFn	RemovePixel function pointer
pargException	Pointer to exception structure that will be filled if an exception occurs

Returns

The newly created IBinarizeCallback

IBinarizeCallback_Destroy()

void IBinarizeCallback_Destroy	(	IBinarizeCallback	argIBinarizeCallback,
		idrs_exception *	pargException
	)

Destroys a IBinarizeCallback handle.

Parameters

argIBinarizeCallback	IBinarizeCallback handle to destroy
pargException	Pointer to exception structure that will be filled if an exception occurs

IBinarizeCallback_RemovePixel()

IDRS_BOOL IBinarizeCallback_RemovePixel	(	IBinarizeCallback	argIBinarizeCallback,
		IDRS_UCHAR const	ucRed,
		IDRS_UCHAR const	ucGreen,
		IDRS_UCHAR const	ucBlue,
		idrs_exception *	pargException
	)

Dropout callback method called at the end of the binarization for each black pixel.

The black pixel is transformed to white if the function returns IDRS_TRUE.

Parameters

argIBinarizeCallback	IBinarizeCallback handle
ucRed	The red component of the pixel's color.
ucGreen	The green component of the pixel's color.
ucBlue	The blue component of the pixel's color.
pargException	Pointer to exception structure that will be filled if an exception occurs

Return values

IDRS_TRUE	If the black pixel must be transformed to white.
IDRS_FALSE	otherwise.
