Introduction

This plugin is used to visually check the quality of images. It allows different views of images as thumbnails, in large display or even in full screen mode. In addition, the full text of the image can be displayed and various functions for download or image manipulation can be activated.

Installation

To use the plugin, these two files must be copied to the following locations:

/opt/digiverso/goobi/plugins/step/plugin_intranda_step_imageQA-base.jar
/opt/digiverso/goobi/plugins/GUI/plugin_intranda_step_imageQA-gui.jar

The configuration of the plugin takes place within its configuration file plugin_intranda_step_imageQA.xml. It is expected to be located under the following path:

/opt/digiverso/goobi/config/plugin_intranda_step_imageQA.xml

Overview and functionality

To put the plugin into operation, it must be activated for one or more desired tasks in the workflow. This is done as shown in the following screenshot by selecting the intranda_step_imageQA plugin from the list of installed plugins.

After the plugin has been completely installed and set up, it will be available for the users of the corresponding tasks. After entering a task, depending on the configuration, some images may be displayed immediately.

If you now enter the plugin by clicking on Plugin: intranda image control, you will see the full display, which includes both thumbnails and a large image display.

Here you can select the desired images to be viewed in higher quality. The large image on the right can be zoomed and rotated for display. You can navigate between the images using the same shortcut keys as in the METS editor in Goobi workflow.

Images can also be displayed in a full-screen view for a larger view. In both the regular image display and the full-screen display, the associated full text can also be shown, provided that this has been generated in advance using OCR.

Besides the pure image display, the plugin can also handle other object types. For example, it is possible to display 3D objects, which can also be rotated and enlarged for display using additional navigation buttons. Depending on the individual configuration, the plugin allows many more functions, which are mostly visible within the thumbnail display. If these functions have been configured in the configuration file described above, they can be used, for example, for downloading PDF files, image files, rotations, flippings, deletions and other operations.

Configuration

The configuration of the plugin is structured as follows:

          4.) project name and step name are *
