CropBorders(Int32,Single,ReferencePoint,Int32,Int32,Int32,Int32,ImagingContext) Method

In This Topic

Detects margins consisting of constant color around a GdPicture image. Returns the coordinate of the cropping selection which can be used by the Crop method. It has a Confidence Parameter where if the lines and borders detection confidence exceeds this value they will be removed, and left as they are if the confidence in detecting them is less than the Confidence Parameter Value.
