LEADTOOLS Image Processing (Leadtools.ImageProcessing.Core assembly)
LEAD Technologies, Inc

LineRemoveCommandEventArgs Constructor (LineRemoveCommandEventArgs)

Example 





Affected image
LEADTOOLS Leadtools.RasterRegion representing the line to be removed. It is the programmer's responsibility to dispose of this region when it is no longer needed.
The starting row of the line. The rows are zero-based.
The starting column of the line. The columns are zero-based.
Length (in pixels) of the line.
Initializes a new LineRemoveCommand with explicit parameters. .NET support WinRT support Silverlight support
