LBitmap::Despeckle

#include "ltwrappr.h"

virtual L_INT LBitmap::Despeckle(void);

Removes speckles from the class object's bitmap. Typically, this function is used to clean up scanned images (such as FAX images). This function is available in Document/Medical toolkits only.

Returns

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

Comments

This function removes 1-pixel speckles, and shrinks some larger speckles. Therefore, in some cases, larger speckles can be completely removed by running it more than once.

To update a status bar or detect a user interrupt during execution of this function, refer to LBase::EnableStatusCallback.

This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
