HolePunchRemoveCommandEventArgs Constructor (HolePunchRemoveCommandEventArgs)








Leadtools.ImageProcessing.Core Namespace > HolePunchRemoveCommandEventArgs Class : HolePunchRemoveCommandEventArgs Constructor
RasterImage object that contains the affected image
LEADTOOLS RasterRegion representing one of the holes of the hole punch pattern. It is the programmer's responsibility to dispose of this region when it is no longer needed.
The bounding rectangle of one of the holes in a hole punch pattern.
Index of the hole within a hole punch pattern. The holes are numbered from 1 to n, where n is the total number of holes in the hole punch pattern.
The total number of holes that make up the hole punch pattern. This value will not change for a particular call to HolePunchRemoveCommand.
Total number of white pixels in one of the holes of a hole punch pattern.
Total number of black pixels in one of the holes of a hole punch pattern.
Initializes a new HolePunchRemoveCommand class object with explicit parameters.
