Hi

Can I use ImageEn for despeckling an image of a scanned document? I could not find any hints in the samples or in the documentation.

Kind regards

if the image is black & white you can use RemoveNoise. There is no procedure to do it with Color images that I know of.

procedure RemoveNoise(Iterations:integer; InvertImage:boolean);

Description

RemoveNoise removes noise pixels using the Kfill algorithm. The RemoveNoise method works only with black/white images (1bit).

Iterations is the maximum number of iterations (from 1).
If InvertImage is True, the image is inverted (negative) when the algorithm works.

Example

ImageEnProc.RemoveNoise(2,false);
