Hi All,<div><br></div><div>I've been playing with the settings for quite a while and the scanning results are still not good enough. </div><div><br></div><div>I was using Xsane 0.996 under Ubuntu 9.10 to scane blank writing pad paper with rule-lines. Note the paper is white and has no </div>
<div>ink at all, except those rule-lines. When I scanned this kind of paper, the result image is always too bright to see the rule-lines (which are my concerns).</div><div><br></div><div>Case1: true-gray model, 600dpi, gamma = 0.3 (minumun), brightness = -100(minumun), contrast = 100(maximum), I get a result with partial visible rule-lines, but</div>
<div>the quality in general is not good. I tried to modify the threshold parameters in the Preference->setup->enhancement, but no luck -- maybe I can't fully understand</div><div>those threshold minimum(0), maximum(20), multiplier(12.5). Anybody can help?</div>
<div><br></div><div>Case2: Black&White, 600dpi, It didn't matter what gamma, birghtness, etc were, the results were almost always a white image -- no rule lines are visible at all. </div><div><br></div><div>Note that if I scanned it in a color model, I can see the rule-lines easily. However, I don't want to do the follow-up converting work; I want everything that comes out of</div>
<div>the scanner to be original and raw. </div><div><br></div><div>If possible, I'd like to scanned in both gray model and BW model respectively, and at the same time make the rule-lines as clear as possible. If anybody has done this before</div>
<div>or have any ideas how to play with those parameters, I'd be more than happy to hear. </div><div><br></div><div>I appreciate your help!</div><div><br>Sincerely,<br>Jin Chen<br><br>
