Finds the skeleton of objects or regions in a bitmap.
virtual L_INT LBitmap::Skeleton(uThreshold, uFlags = 0)
Threshold value used to binarize the bitmap before finding the skeleton. This parameter is ignored if the bitmap is a binary bitmap. The valid ranges are:
Reserved for future use. Must be 0.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function finds the skeleton of regions or objects in a binary bitmap. The white color represents the objects and the black color represents the background. If the bitmap is not a 1-bit image, the threshold will be used to transform the bitmap into a binary image before finding the skeleton.
If the bitmap has a region, this function works only on the region.
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.
This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.

This example loads a bitmap and finds its edges using LBitmap::EdgeDetector then produces the skeleton of these edges
L_INT LBitmap__SkeletonExample(LAnimationWindow * LAniWnd)
/* Find the edges in the bitmap*/
nRet =LAniWnd->EdgeDetector (60, EDG_SOBEL_ALL);
