Re: Spreads development environment

On Ubuntu, you will have to install "turbojpeg-devel". See this GitHub issue for a longer discussion of the relocation error: https://github.com/jbaiter/jpegtran-cffi/issues/5 On Debian, "libjpeg8-dev" is enough, you will only get a line on stderr that it can't find turbojpeg.h, ...

Re: CHDKPTP debian package

Great to see somebody else work on this, too :) I've had chdkptp packages in the spreads repository (http://apt.diybookscanner.org/raspbian/pool/main/c/chdkptp/) for a while now, though it was done in a pretty messy way. If you feel confident and want to contribute the package to the official Debian...

Re: Scan Tailor is looking for a new maintainer

What tool do you use for cropping to a page? ST Enhanced has this option, but it isn't as reliable as I'd like? If I can reliably crop to a page, then I agree that the deskew/binarize would be pretty reliable using ST. The Spreads web interface can do that. You take a shot, then select the area tha...

Re: Installing SpreadPi on your Raspberry Pi

Just a quick note, the URL posted is not the correct address for the latest image. Instead it should be http://buildbot.diybookscanner.org/nightly/spreadpi-latest.img.7z This is a regular disk image (which can be written 1:1 to the SD-Card) compressed with 7Zip. Use 7Zip to extract it and then use W...

Re: Post-processing tweaks needed!

I really recommend you take a look at some of the free software available. My prefered stack is using ScanTailor to postprocess and clean up the images, then I run the resulting TIFs through Tesseract for OCRing. In the last step, pdfbeads separates Illustrations from Text and encodes the former wit...

Re: Spreads Problems and Solutions

Hey duerig, thank you so much for the detailed feedback! I'm painfully aware that the software is in a pretty rough state at the moment, especially on the documentation and installation front. I'm working together with someone to rework the documentation, but I can't say yet when it will be done. Ju...

Re: SpreadPi: The new DIY Book Scanner control system.

spomwii, the issue with footpedal-induced shots not being registered by the counter is due to a bug in the event-handling code that has I've already fixed in my not yet published postprocessing branch. I will merge it once I am home from my vacation and added some tests :)

Re: Introducing spreads: command-line workflow tool

The command you posted does not install the latest release, but actually the latest HEAD (== latest development changes), so pretty much what you want. Please try uninstalling the old version first ('pip uninstall spreads') and/or work from a Python virtualenv to avoid conflicts. Also, can you post ...
