11.1 OCR Attributes
Abschnitt hinzufügen

The OCR attributes determine the settings with which the OCR engine should process an image. Depending on the OCR engine used (ABBYY or Tesseract), the setting options vary.

The most important settings are explained in the following section.

11.1.1 Selecting and Setting Attributes

Set global OCR attributes: These settings are used by the OCR Engine whenever no job or page-specific settings are made or the OCR settings are controlled by the Job Index.

Set OCR attributes for current job: The set values are used for the OCR processing of the current job and are only valid for this job.

Set OCR attributes for current page: The set values are used for the OCR processing of the current page and are only valid for this page.

11.1.2 Reset attributes

reset global OCR attributes… The OCR attributes are reset to the original default values set at the time of installation.

Reset OCR attributes of the job… The OCR attributes are reset to the global settings

Reset OCR attributes of the image… The OCR attributes are reset to the job or global OCR attribute settings

11.2 Set OCR Attributes
Abschnitt hinzufügen

Since both OCR engines offer a variety of settings that are unfortunately not always documented or comprehensible, a drop-down list below the OCR Attributes dialog allows you to limit the number of settings based on an experience level (Beginner, Advanced, Expert).

The attributes for the OCR engines are preconfigured to the extent that the user usually only has to select the language and, in the case of ABBYY, the font.

Die wichtigsten Einstellungen bei beiden OCR Engines sind Sprache und Schrift. Werden diese nicht korrekt ausgewählt wird das Ergebnis entsprechend schlecht ausfallen.
