   RasterRegion^ region,
   int startRow,
   int startColumn,
   int length
)

Parameters

image: Affected image
region: 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.
startRow: The starting row of the line. The rows are zero-based.
startColumn: The starting column of the line. The columns are zero-based.
length: Length (in pixels) of the line.
