InvertedTextCommandEventArgs Constructor
See Also  Example
Leadtools.ImageProcessing.Core Namespace > InvertedTextCommandEventArgs Class : InvertedTextCommandEventArgs Constructor



image
RasterImage object that references the affected image.
region
LEADTOOLS Leadtools.RasterRegion representing the inverted text to be removed. Dispose of this region when it is no longer needed.
boundingRectangle
The bounding rectangle of the inverted text region being processed.
whiteCount
Total number of white pixels in the inverted text region being processed.
blackCount
Total number of black pixels in the inverted text region being processed.
Initializes a new InvertedTextCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7
