NPrinting report images are not the same as in NPrinting 16 after migration to NPrinting 19 or higher versions

[Frank_S]

Issue reported:

• Recently used the NPrinting report migration tool from version 16.3.0.0 to version February 2020 SR1 and we encountered problems in displaying graphics as expected after migration.

Environment:

• Migration from NP 16.3 thru 16.9 to NPrinting Web Console

What is the expected result?

• The same look and feel of the objects

What is the actual result?

• Image dimensions have shifted dramatically

Resolution

This described behavior is expected as detailed in NPrinting Nov. 2019 and higher+:

To revert to the original image behavior, follow the steps under Changing how QlikView charts are exported on the same page.

Excerpt from the link above.

• QlikView would screenshot the chart, and then it would be resized. You can revert to this older behavior in newer versions of Qlik NPrinting by editing the QlikView.config file on the NPrinting Engine computer ( this must be done on each NPrinting engine computer. If the QlikView desktop on the NP engine computer is reinstalled, this step may need to be repeated).

Do the following to resolve the issue:

1. Stop the Qlik NPrinting web engine service.
2. Open the QlikView.config configuration file.

The default path is: C:\Program Files\NPrintingServer\NPrinting\Engine\QlikView.config

Next

1. Find the useAdvancedImageExport flag.
2. Set value to "false"
3. Save the file and restart the NPrinting services.

Cause

• Change in internal image rendering method in NPrinting 19 and higher versions
