LBitmap::BinaryFilter

Show in webframe

#include "ltwrappr.h"

virtual L_INT LBitmap::BinaryFilter(pFilter, uFlags = 0)

pBINARYFLT pFilter;	/* pointer to the binary filter to use */
L_UINT32 uFlags;	/* flags */

Imposes a binary filter on the class object's bitmap.

Parameter	Description
pFilter	Pointer to the binary filter to use. You can use one of the following predefined filters:
	Value	Meaning
	BFLT_EROSION_OMNI BFLT_EROSION_HORZ BFLT_EROSION_VERT BFLT_EROSION_DIAG	[#define] Shrinks black objects in the image. The effect is biased in the specified direction.
	BFLT_DILATION_OMNI BFLT_DILATION_HORZ BFLT_DILATION_VERT BFLT_DILATION_DIAG	[#define] Enlarges black objects in the image. The effect is biased in the specified direction.
uFlags	Reserved for future use. Must be 0.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.
