DocWash™

Some documents may prove impossible to scan with acceptable quality. The Docwash function in PixEdit is a tool for manual thresholding of very dirty or difficult documents. Modern scanners from Vidar, Xerox, Contex, OCE and others have built-in automatic thresholding logic, resulting in high quality monochrome scans. However, very old or faded documents may still be difficult to scan. For such difficult documents, using the Docwash tool may be the only solution to this problem.

Docwash thresholding dialogue The washing process is performed by first selecting the size of the washing tool by digitizing a rectangle. Move the rectangular wash area by clicking inside the rectangle and holding the mouse button down while moving the rectangle. If the image inside the area is too dark or too light, adjust the threshold with the mouse wheel. A new rectangle with another size can be selected. PixEdit will perform autopanning when you reach any edge of the main window.
