Overview

Refer to Cleaning - up 1-Bit Images

Remarks

(Document/Medical) Removes horizontal and vertical lines in a 1-bit black and white image.

This method removes horizontal and vertical lines from scanned text documents. If the lines pass through text, the parameters can be set to remove or preserve the text.

This method works only on 1-bit black and white images.

If a region is selected, only the selected region will be changed by this method. If no region is selected, the whole image will be processed.

The behavior of this method can be further modified by using the LineRemove event.

To "fine-tune" the performance of this method, try modifying the values for iWall, iGapLength and iVariance.

This method triggers both the LineRemove event and the ProgressStatus event.

This method does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this method.
