About

Scan Tailor is an interactive post-processing tool for scanned pages. It performs operations such as:

You give it raw scans, and you get pages ready to be printed or assembled into a PDF or DJVU file. Scanning, optical character recognition, and assembling multi-page documents are out of scope of this project.

Scan Tailor is Free Software (which is more than just freeware). It’s written in C++ with Qt and released under the General Public License version 3. We develop both Windows and GNU/Linux versions.

History and Future

This project started in late 2007 and by mid 2010 it reached production quality.

In 2014, the original developer Joseph Artsimovich stepped aside, and Nate Craun (@ncraun) took over as the new maintainer.

For information on contributing and the longstanding plan for the project, please see the Roadmap wiki entry.

For any suggested changes or bugs, please consult the Issues tab.

Usage

Scan Tailor is being used not just by enthusiasts, but also by libraries and other institutions. Scan Tailor processed books can be found on Google Books and the Internet Archive.

  • Prolog for Programmers. The 47.3MB pdf is the original, and the 3.1MB pdf is after using Scan Tailor. The OCR, Chapter Indexing, JBIG2 compression, and PDF Binding were not done with Scan Tailor, but all of the scanned image cleanup was. [1]

  • Only set options from command-line if they were explicitely specified

    Only set options from command-line if they were explicitely specified

    This patch fixes an issue with scantailor-cli that caused settings from the configuration file to be overwritten by the command-line defaults. (see https://github.com/DIYBookScanner/spreads/pull/112#issuecomment-48022697) This occured due to the fact that QMap<QString, QString> m_options in the CommandLine class would set a key once it was queried.

    As an example, the following method would be called before a later call to hasColorParams, which checks if an option was set from the commandline by calling contains on the QMap:

    output::ColorParams::ColorMode
    CommandLine::fetchColorMode()
    {
        // This seems to set "color-mode" in the QMap
        QString cm = m_options["color-mode"].toLower();
    
        if (cm == "color_grayscale")
            return output::ColorParams::COLOR_GRAYSCALE;
        else if (cm == "mixed")
            return output::ColorParams::MIXED;
    
        return output::ColorParams::BLACK_AND_WHITE;
    }
    

    When the program would later check for a user-supplied color parameter from the command-line via hasColorParams it would always return true, even though the --color-mode flag was never set.

    As a solution, the new code now only calls fetch* methods if the corresponding has* method returns true.

  • fix crash if output has no margins

    fix crash if output has no margins

    resolves #210 ST crashes on line 255.

    The problem must be with rounding rectangles in float coordinates to rectangles in integer coordinates. In some circumstances it rounds to -1 pixel for output rect and to +1 pixel for working rect. Working rect size becomes 1 pixel bigger than output page size and everything collapses. And non-zero margins seems to save ST from that. toAlignedRect() is using ceil() instead of round() for float coordinates conversion so the sizes should always match.

  • Fix compilation with GCC 6

    Fix compilation with GCC 6

    GCC 6 defaults to a newer C++ standard version. C++11 introduced a new overload for push_back so it is now sometimes necessary to specify which overload is required. C++11 also introduced std::bind so we need to specify the namespace when using boost::lambda::bind.

  • respect CFLAGS and CXXFLAGS

    respect CFLAGS and CXXFLAGS

    Setting CMAKE_C_FLAGS and CMAKE_CXX_FLAGS without including their existing contents causes any provided CFLAGS and/or CXXFLAGS to be ignored.

    These should be respected, if set (distributions commonly have defaults they expect to be used). The $default_flags_ tweak is just to avoid duplication - distros will typically set CXXFLAGS to include all the same stuff as CFLAGS, so if you include CFLAGS in CMAKE_C_FLAGS then include CMAKE_C_FLAGS in CMAKE_ CXX_FLAGS, you'll wind up with lots of flags repeated.

  • Copy Featured branch into main scantailor project

    Copy Featured branch into main scantailor project

    Hi,

    I couldn't find a repository for the "featured" branch of scantailor, so I've attempted to recreate it based on the tarballs I had available, specifically:

    scantailor-featured-2013.02.15.tar.gz scantailor-featured-2013.04.10.tar.gz scantailor-featured-2013.05.31.tar.gz

    I've tried to make it one commit per "feature" as listed at http://sourceforge.net/projects/scantailor/files/scantailor-devel/featured/ but in some cases there were changes to a feature after the first release containing that feature, so there might be a second commit later on. They're all labelled with the feature name in the commit in any case. I've tagged the commits corresponding to the releases too:

    scantailor-featured_2013.02.15 scantailor-featured_2013.04.10 scantailor-featured_2013.05.31

    I don't suggest merging this into master, rather that it'd be good to copy it over to the main scantailor repository to make it easier to cherry-pick any of the features for the main branch.

    Thanks, Andy

    These 3 commits were "cherry-picked" from master branch and applied to enhanced branch. They are required to build vanilla enhanced branch with up-to-date toolchain (boost, gcc). The description of a last one commit is a bit spoiled.

  • Tiff compression may be changed in settings file

    Tiff compression may be changed in settings file

    This PR addresses #201 and demonstrates settings file usage. It contains 3 commits:

    1. Enforcing settings storage as ini file among platforms. Which is also submitted standalone in #266
    2. Fancy static helper class that allows easily call callback function at application start to make sure settings file contains hints. As Qt settings file implementation strip outs comments.
    3. Tiff compression change implementation based on settings file. 2 commits above allows to implement it with only changing one tiff cpp module.

    As for setting itself, you'll find following lines in Scan Tailor.ini:

    [tiff]
    compressionMethod-hint="Tiff compression method may take following values: NONE, CCITTRLE, CCITTFAX3, CCITT_T4, CCITTFAX4, CCITT_T6, LZW, OJPEG, JPEG, T85, T43, NEXT, CCITTRLEW, PACKBITS, THUNDERSCAN, IT8CTPAD, IT8LW, IT8MP, IT8BL, PIXARFILM, PIXARLOG, DEFLATE, ADOBE_DEFLATE, DCS, JBIG, SGILOG, SGILOG24, JP2000, LZMA. Default value: LZW. Note: not all methods may be implemented by libtiff. The error messages are printed to console."
    compressionMethod=LZW
    

    I've tried some values - NONE and DEFLATE works. Several, like JP2000, wasn't implemented in my system. JPEG complains on incompatible image settings set up. The error messages are shown in console. Scan Tailor's GUI show no error dialogs in case of problems - just stops doing anything without refreshing page thumbnail image.

  • Fix build with boost 1.60

    Fix build with boost 1.60

    Always use fully qualified boost::lambda::{bind,_1,_2}

    With boost 1.60 there's a namespace conflict between boost::bind and boost::lambda::bind and placeholders are no longer in global namespace, so use fully qualified names for these.

    It is advised to switch away from "using namespace" statements completely.

    Fixes for some German translations, especially

    • keyboard shortcuts. They were translated, which meant they did not work.
    • “Every other page” was translated as „alle anderen Seiten“. That was wrong. It translates back as “All other pages“, meaning all pages, with the exception of this page. Not what this does.

    There are some other strings i came across that i translated.

  • Generate and upload AppImage

    Generate and upload AppImage

    This PR, when merged, will compile this application on Travis CI upon each git push, and upload an AppImage to your GitHub Releases page.

    Providing an AppImage would have, among others, these advantages:

    • Applications packaged as an AppImage can run on many distributions (including Ubuntu, Fedora, openSUSE, CentOS, elementaryOS, Linux Mint, and others)
    • One app = one file = super simple for users: just download one AppImage file, make it executable, and run
    • No unpacking or installation necessary
    • No root needed
    • No system libraries changed
    • Works out of the box, no installation of runtimes needed
    • Optional desktop integration with appimaged
    • Optional binary delta updates, e.g., for continuous builds (only download the binary diff) using AppImageUpdate
    • Can optionally GPG2-sign your AppImages (inside the file)
    • Works on Live ISOs
    • Can use the same AppImages when dual-booting multiple distributions
    • Can be listed in the AppImageHub central directory of available AppImages
    • Can double as a self-extracting compressed archive with the --appimage-extract parameter
    • No repositories needed. Suitable/optimized for air-gapped (offline) machines

    Here is an overview of projects that are already distributing upstream-provided, official AppImages.

    PLEASE NOTE: For this to work, you need to set up GITHUB_TOKEN in Travis CI for this to work; please see https://github.com/probonopd/uploadtool.

    If you have questions, AppImage developers are on #AppImage on irc.freenode.net.
