Does VintaSoftImaging has this function

this means:
The removal of a specific color from a scanned image. Typically used for preprinted forms, so that the form itself does not appear in the scanned image, leaving only the information filled in by the user. This increases OCR effectiveness, and decreases data storage and bandwidth requirements.

You can use the Vintasoft.Imaging.ImageProcessing.Color.ColorBlendCommand if you want to dropout the color from the image.

Here is an example how to dropout red color from the image:

Code: Select all

ColorBlendCommand command = new ColorBlendCommand(BlendingMode.Darken, Color.FromArgb(0, 255, 255));
