Description This function will morphologically skeletonize the binary image. The function works for only 1 bit per pixel images. The binary skeletonization of an object defines a unique compressed geometrical representation of the object. Skeletonization is often referred to as the Medial Axis Transform. Morphological skeleton is processed by binary thinning operation several times iteratively until no further changes occur.
Examples
Syntax RetVal = [BiFilter.]BinarySkeleton hDib MaxStep BackGrndisBlack ShowProgress hWnd
Returns RetVal Long The handle of new filtered DIB, 0 if an error occurred, or –1 if the BIFilter.dll does not installed.
Remarks hDIB Long Handle of the image to filter.
MaxStep Long This parameter specifies the maximum number of thinning operations. If MaxStep is 0, binary skeletonizing will be processed iteratively until no further changes occur.
BackGrndisBlack BOOL Specifies the color of BackGround.
iShowProgress short This parameter specifies the displaying of the progressbar and the preview dialog.
Available values:
DISPLAY_NONE (0) – The progressbar and the preview dialog will not display before filtering.
DISPLAY_PROGRESS (1) – The progressbar will display during filtering procedure.
DISPLAY_DIALOG (2) – The preview dialog will display before filtering. This dialog shows the part of the image before and after filtering.
DISPLAY_BOTH (3) – The progressbar and the preview dialog will display.
IMPORTANT: The preview dialog will only display, if there is BIDlgs32.dll installed.
hWnd Long Handler of the parent window.
