Scan Tailor (tailor in English - a tailor) - is an interactive tool for post-processing of scanned pages. It makes operations such as cutting pages, the compensation angle, add / delete fields, and others. You give him the raw scans, which results in the page, ready for printing or assembly in PDF or DjVu file.
Scanning, OCR, and build multi-page documents are not included in the project objectives.
The program is developed for Windows, and for GNU / Linux (and other Unix-like systems).
Installation and first start
For Windows Versions for Windows comes in the form of an installer. Install the program and run it through the menu.
For GNU / Linux
If your distribution does not have Scan Tailor'a in its repositories (and the only one I know of distribution, which is - it is Alt Linux), then you have to build it from source. After assembly, you can run Scan Tailor via Alt + F2, typing the command there "scantailor" (without the quotes).
Once launched, the main program window looks like this:
In the central panel we see the paragraphs "New project ..."," Open Project ... " a list of recent projects, if any.
So, let's create our first project. First, we need some raw materials - Scan Tailor requires the presence of at least one file in the project. This source material can be scanned pages of the book (you can turn) or a magazine.
Click on "New Project ..." - Opens dialog "Project Files".
"Directory entry" - the folder where the original scans.
"Output Directory" - the folder where are stored, processed scans.
"Files not in the project" - the files in a folder specified in the Directory entry, but not made to the draft.
Files in the project "- the files made to the draft, not necessarily from the directory entry. The project can make the files from different directories, which should contribute to the project files from one directory entry, then change it, make the files from there, and so on.
Buttons ">>" and "<<" between "Files not in the project" and "Files in the" move files from one list to another. Not move all the files, but only lighted. It is possible to light all the files click "Select All", may be exposing or rent flare individually - via Ctrl + Click, or a range - through Shift + Click.
Once you've made the files in the project (and supported files *. tif, *. tiff, *. png, *. jpg, *. jpeg), click OK. Usually, this process of creating the project ends, but if caught in the project files with unspecified or clearly incorrect DPI, then open a dialogue "Fix DPI".
To begin with, what DPI stands for "dots per inch" ( "dots per inch), and defines the correspondence between the physical (inches, centimeters), and pixel size. Pixel - is the point of which consist of digital images. For example in the screenshot above, we see two scans with the size of 3494 x 2550 pixels. If we knew the DPI of the scan, we could calculate their physical size. If for example, assume that their DPI 300x300 (300 horizontal by 300 vertical), then the physical dimensions are:
(3494 / 300) x (in 2550 / 300) = 11,6 x 8,5 inches = 29,6 x 21,6 cm
In this case the way it is. DPI is determined by the scan settings, and usually software to scan itself exposes the files in the correct DPI. However, further manipulation of the image, it can easily get lost, so it must be restored to normal operation Scan Tailor. The most common DPI - 300 and 600. Horizontal and vertical components of the DPI is usually coincide.
Return to dialogue "Fix DPI". In the tab "should fix" lists only those files that DPI does not specify or clearly wrong. In the tab "All Pages" (Not to be confused with the same host drop-down list) lists all the files at all. They also can change the DPI. If we know that all the files in the project are 300 x 300 DPI, then can one go to ask the DPI for all files. To do this, go to the site, "All pages" (not to be confused with the tab), ukazyaem DPI, click apply. You can also specify the DPI for groups of files with the same pixel size, and also for individual files. Files that have been identified DPI, disappear from the tab "should be corrected. When the tab is completely empty, will be active, click OK. Clicking it, the process of creating the project will be completed.
DPI, which you specify are written to the files - they are only stored in the project file Scan Tailor.
At stages of processing "Correction orientation" and "Cutting pages" provides the ability to add / remove files from the project with the help of pop-up menu, called by the PC mouse on the correct page preview tape:
When you try to add a file to the explicitly Invalid DPI program asks him to fix:
Keep in mind that there is currently no way to change the DPI for a file in the already created project, as well as ways to remove or add at the same time a group of files in an existing project. The emergence of these features are expected in future versions.
The concept of processing scans Scan Tailor
First, you need to understand the general concept of the program. Processing of the scanned pages in the Scan Tailor reminds conveyor at the plant. And there and there is a stage, each of which is some specific manipulation with the product (scan).
Let's look at the main program window:
Top left we have a list of stages (1), and a preview tape (4) just can thus be considered a pipeline. It is important to understand that as a regular assembly line if the product reached a certain stage, then all the previous stages have been completed, and in strict sequence. If you say once stood on the stage of "useful areas", the page that you work with at this stage still pass all the previous stages, you simply do not see. At any time you can return to any of the previous stages to see, and if necessary to correct that with the scan was done at this point.
Round button "Play" in front of each stage just runs the batch processing, ie вышеописанный конвейер. above described conveyor. Pages, one by one, pass all stages of processing, including the current stage. "Pass through all stages of processing" - does not necessarily mean "processed". For example if the scan had already been cut, when he again gets to the stage of cutting - again it will not be cut, unless you had changed something important, such as its orientation. Stop batch processing is possible at any moment a large round button "Stop", emerging during the processing of the main work area (3).
Another small detail - none of the stages, except the last stage, "Conclusion" is not recorded on the disk the resulting image. The fact that all stages except the last - a purely analytical. Their result - not a new image and new information on the original image.
The rest of the main window: (2) Options for the current processing stage. (3) Main working area that displays the image itself, as well as tools for manipulating them, (5) line tips - here you can see an interactive prompt management program. (6) button "Keep active page in the field of view." In the depressed condition switches the program to monitor the current regime of processed Pages tape preview. Program menu
File menu New Project ... Open Project ... Save Project Save Project As ... Close Project Output
All this needs no explanation, except for item "Close Project". This command closes the project, but not the whole program. The main window contains a type which it has immediately after the start, that is shown here, this panel:
Tools Menu: Debug mode - is intended only for developers. After processing a single page, in the central area of the tabs appear on the intermediate results of processing. Settings - designed to further customize the program. In the present configuration can only try to enable the option "Enable 3D acceleration for the user interface. This option is broken on some models of video cards, and because the default is disabled.
