Initializes a new InvertedTextCommand class object with explicit parameters.
Syntax
Parameters
- image
- RasterImage object that references the affected image.
- region

- 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.
