InvertedTextCommandEventArgs Constructor (InvertedTextCommandEventArgs)








Leadtools.ImageProcessing.Core Namespace > InvertedTextCommandEventArgs Class : InvertedTextCommandEventArgs Constructor
RasterImage object that references the affected image.
LEADTOOLS RasterRegion representing the inverted text to be removed. Dispose of this region when it is no longer needed.
The bounding rectangle of the inverted text region being processed.
Total number of white pixels in the inverted text region being processed.
Total number of black pixels in the inverted text region being processed.
Initializes a new InvertedTextCommand class object with explicit parameters.
Syntax
