cvScharr

Module:	OpenCV

Calculates the first x- or y- image derivative using Scharr operator.

Name	Type	Range	Description
inSrc	Image		Source image.
inDDepth	Integer *		Destination image depth.
inXOrder	Integer	0 - 1	Order of the derivative x.
inYOrder	Integer	0 - 1	Order of the derivative y.
inScale	Real		Scale factor for the computed derivative values.
inDelta	Real		Delta value that is added to the results prior to storing them in dst.
inBorderType	CvBorderType		Pixel extrapolation method.
outDst	Image		Output image.

This filter can throw an exception to report error. Read how to deal with errors in Error Handling.

List of possible exceptions:

Error type	Description
DomainError	Input image must have pixel type different from Int8 and Int32 in cvScharr.
DomainError	Input image must not be empty in cvScharr.

This filter is available on Basic Complexity Level.
