Re: Some Scan Tailor suggestions

There is no need to wait. It will simply start calculating and start over as soon you touch a setting. I click on output, ignore any animation going on, set to whatever I need, open the apply to dialog and so on. There would be no gain in speed if the calculation would not start. There are other pla...

Re: Understand DPI, it affects many things in Scan Tailor

For Mac users as myself, finding the correct DPI works as follows. I use the shareware GraphicConverter from http://www.lemkesoft.de/. It has some rudimentary processing possibilities and I never needed more. I bet you can do the same in GIMP or whatever... I double click my image, which usually pop...

Re: [Suggestion] Show page dimensions under Content

+ 1 It would be also great, to be able to define the final size independently of any given page. Not the biggest page would be the reference, but rather a globally defined size (pixel or size or a specified page). If the layout would require a larger size, it would be cut and a simple warning be add...

Re: Sort question - even odd problem

I would love to see the "apply to every other page" also in other stages. Most important obviously would be the Margins stage, but the Split Pages would make sense as well, as the automatic detection often fails... I would not mind if the "Apply to..." would be the same for all. (simply reuse of the...

Re: Reasonable PagesPerHour for first time & length of proje

I have a simple scanner with only one camera. I get maybe 400 pages per hour, but only for the photos. It took me less than a day to build it, as its the opposite of fancy - its dead simple... I use Scantailor to get cleaned images. It depends a lot on the sort of books you scan, but there is a lot ...

Re: Open Source Hardware License Discussion.

Patents and copyright are very different beasts. A patentable invention does not need this sort of protection, because if its not patented, anybody can use it anyway. A different story is certain parts of an invention like PCB boards, schematics and so on. For these apply a copyright. But for copyri...

Plateless and transportable minimal scanner...

Here is another one. To be honest its not as fast as the more heavy models, but you can put it into your trouser pocket. Ideal for libraries... Its based on a table music stand and a pair of hair clips... Will this scan a book??? Will this scan a book.jpg unpacked: unpacked.jpg prepared: prepared.jp...

Re: Simple new scanner

When you were scanning, did you find that books would slide down the 45 degree half-platen? Or did they stay where they should be? I supported them simply with a rest of the same (thick) plank I made the stand, and/or with another book. Look at the second photo, its quite obvious. This is pretty fl...

Simple new scanner

Inspired by all the works shown here, and driven by the need to keep costs low, I created a simple but robust scanner. I scanned already some dozen books successfully with it... I built a simple wooden construction to hold the book (no costs, as I found the wooden parts in my basement). It is simpli...

Re: Medium range cameras

I just bought a Samsung ES17 for less than 50 Euros. It gives me 12 mega pixels resolution and I am scanning like hell without any of the other requirements fullfilled. The result is just fine, I get about 350 dpi for a DIN A4 or US letter size page. Higher resolutions for smaller books. 8MP will sc...
