Sorry to bother you again.
I have recently read in some forums that the lossless cropping of a jpeg file is only possible if you crop it respecting some kind of proportion in the cropping rectangle. I found that in your program you can freely select the area to crop, exactly where you want.
Thanks

If  I drag and drop a single jpeg, it doesn't let me push the Crop button.
Is it normal?

Thanks

Oh, I see now, I had the wrong theory then that it was going to move...
Anyway, I have tested again bookcrop I found it really fast with GraphicsMagick-1.3.17-Q8, and experimented with the threshold, with a value of 40

Yes, I will have a use for it.  
I'm planning on cropping the jpgs before feeding them to Scan Tailor. I will crop them to get rid of headers and footers and the opposite page.

I don't have a DIY hackerspace scanner (I only use one camera and a crappy cardboard 'thingy')
But for those with one, I think they will have to draw bigger rectangles (in height), because the 'text zone' is going to be moving down as they advance in the scanning process till getting to the middle of the book (the thicker the book, the more the text is going to move)

Sorry, I thought it was only the bookcrop.exe (my bad)
Lossless, wow, I would have to read more into jpegtran... My understanding was that once you modify a jpeg, you were loosing quality
All working perfect, except the side panel (the one with the threshold). It always stays on top, like 'pinned'
Also it would be perfect if you could 'readjust' the rectangle after drawing it

Thanks again

What is the quality loss in the jpgs after the crop?

Also, it says:

GraphicsMagick not found. Install it and try again

But there is no way to install this, it just runs from the exe, am I wrong?

I am in Win 7 x64

Thanks
