The Engauge Digitizer tool accepts image files (like PNG, JPEG and TIFF) containing graphs, and recovers the
data points from those graphs. The resulting data points are usually used as input to other software applications.
Conceptually, Engauge Digitizer is the opposite of a graphing tool that converts data points to graphs. The process
is shown below — an image file is imported and then digitized within Engauge by placing points along axes and curves.
Data points can be transferred to other software applications by exporting to a text file, or directly using copy and
paste. Work can be saved into an Engauge DIG file for later editing.
Engauge users range from one-time users digitizing a single image file, to large government and commercial
organizations managing databases of thousands of image files.

Version 6.1 (10/31/2015) can load DIG files from earlier versions of Engauge Digitizer.
-
Version 6.0 (10/23/2015) of Engauge 6 was released. This is a major rewrite of the 10 year old Engauge Digitizer
software project that once lived on sourceforge.net. The replacement is required since the Qt3 toolkit that
Engauge relies on is disappearing. Engauge-Digitizer uses the new Qt5 library which should be available for
many years, and also offers many new features.
Installation
Engauge can be installed using repository packages for popular Linux distributions of Linux or the Mac App Store for OSX (easiest methods), or by downloading
pre-built binaries for Windows and Linux (slightly less easy). The pre-built binaries are available from the engauge-digitizer
project at github.com, in the Releases page. The final option
for installing is to build the software from the source
code (very difficult). Building the software from the source code is accomplished by following the steps in the BUILD
file that is found in the main directory. The build process can take as little as one hour in Linux or as long as
several hours in Microsoft Windows.

Этот оцифровывающий программный инструмент преобразует файл изображения, показывающий график или карту, в числа. Файл изображения может посходить от сканера, цифровой камеры или скриншота. Номера можно прочитать на экране, а также написать или скопировать в электронную таблицу.
Инструмент Engauge Digitizer принимает файлы изображений (например, PNG, JPEG и TIFF), содержащие графики, и восстанавливает точки данных из этих графиков. Полученные точки данных обычно используются в качестве ввода в другие программные приложения. Концептуально Engauge Digitizer является противоположностью инструменту графики, который преобразует точки данных в графики. Процесс показан ниже — файл изображения импортируется, оцифровывается в Engauge и экспортируется в качестве таблицы числовых данных в текстовый файл. Работа может быть сохранена в файле Engauge DIG.
Этот инструмент широко используется. Пользователи варьируются от одноразовых пользователей, оцифровыв один файл изображений, до крупных государственных и коммерческих организаций, управляющих базами данных из тысяч файлов изображений.

Описание
Это программное обеспечение для оцифровки с открытым исходным кодом преобразует файл изображения, показывающий график или карту, в числа. Файл изображения может быть получен со сканера, цифровой камеры или скриншота. Числа можно прочитать на экране и записать или скопировать в электронную таблицу.
Процесс начинается с файла изображения, содержащего график или карту. Конечным результатом являются оцифрованные данные, которые можно использовать в других инструментах, таких как Microsoft Excel.
