Detailed changelogs for the Continia Document Capture Service

Added the optional app setting ABBYY Max. Recognition Processes to limit the number of FineReader Engine recognition processes. The engine starts one process per page of a multi-page document, up to the number of physical CPU cores – and each process keeps the memory it used at its peak until the service stops.

On servers with many cores, this could use too much memory. Add the following snippet to appSettings in the service's .exe.config to set a limit to the number of processes that will be run. If not set, empty or 0, it keeps the engine's default. The value in use is written to the event log during startup.

<add key="ABBYYMaxRecognitionProcesses" value="1" />

Upgraded the Abbyy FineReader Engine from 12.7.4.1 to 12.8.2.0.

FineReader Engine 12.8 depends much more on the recognition languages than 12.7. With only the default language (i.e.: English), letters outside the English alphabet are replaced or dropped (e.g.: 'ø' read as '0', 'é' read as 'e', 'ß' and 'æ' are dropped).

When the expected languages are set in the category's config.xml, 12.8 reads these letters correctly – in several cases better than 12.7. If uncertain which languages to expect, use: <Languages><Language>English,Danish,German,French,Spanish,Dutch</Language></Languages>

This replaces the 28.01 note on 12.8.0.1: the dropped diacritics were caused by the language setting, not by the engine. Known issues with 12.8: 'I' is occasionally read as '1' in invoice numbers (e.g.: I-77777), and en dashes (–) are read as em dashes (—).

We have updated the ABBYY Installer to contain a newer version of ABBYY (12.5.6.12).
The full changelog of the ABBYY version can be read here:https://www.abbyy.com/finereader-engine-downloads/windows/

As we have only changed the ABBYY component, we have not changed the version number of the installed Continia Document Capture for NAV - Service (x64). the version number is still 8.00.

Fixed an issue in the Document Capture Service when downloading attachments from email accounts using EWS. When the error occurred, emails for the relevant document category were not processed. The event log displayed the following:

• Unable to cast object of type 'Microsoft.Exchange.WebServices.Data.ItemAttachment' to type 'Microsoft.Exchange.WebServices.Data.FileAttachment'".

Fixed an issue where the Document Capture service would use the PDF file to create the png-files used for showing the document pages in the web client. However, that behavior was not correct, as the OCR processing is based on a skew-corrected version of the document. This issue could cause the process of manually capturing values in the web client to produce unexpected results.

The service has now been changed to obtain the correct coordinates aligned with the web client's visual presentation.
