Threshold in case of light color pencil

Added by Dean B almost 12 years ago

Hi,

I have scanned questionnaires, but they are scanned in color, not in black and white.

In some case box is completely marked, but color is very light, therefore threshold is not reached.

Is there an option within amc to solve this?

If not I'll try to reprint pdf in B&W.

Please see example in atachement.

Thank you.

Regards, D

Not really related to color/BW conversion, but perhaps you can try to increase a little the Black&white conversion threshold value from Edit/Preferences/Scan.

Is Black&White conversion threshold == Default darkness threshold, please see attachment ?
I have version 1.0.3 installed.

Thank you. D

No, it is not.

You need AMC 1.1.1 or higher to get this option.
