Remarks

An inverted Leadtools.Workflow.Raster.WorkflowImage is an image that has text or other objects in high contrast color on a low contrast background, for example white text on black background. This activity can check if an image is inverted as well as auto-correct.

This activity can only detect an entire image, to search for and correct specific inverted areas or regions in an image, use InvertedTextActivity.

A common source of inverted images are blacn and white bitmaps saved with non-standard palette by some applications.

This activity does not support signed data images.

For more information, refer to Cleaning Up 1-Bit Images.
