BIRT Reporting Font issue from Webportal

sgnan · November 20, 2023, 10:00am

Hello,

I have a workflow in Knime 4.7.7 that creates a report. When I run it locally, the PowerPoint report is correctly visualized.

However, when I run it from the web portal, all the fonts in the PowerPoint are converted into Times.

I already asked the admin of the KNIME server to install the fonts I need, but this did not solve the issue. Any idea of what could be the source of the issue?

I am adding the workflow I used to create these snapshots. PPT_Report.knwf (12.9 KB)

Thank you in advance.

Best,

Ste

Hi @sgnan,

Does it also happen when you export the report in other file formats like PDF or is it specific to PowerPoint?

Hello @armingrudd ,

The issue is present in both PPT and PDF formats.
I have just tried to export it as an HTML and a Word file. In those formats, fonts are correctly configured.

Best,

Apologies for the delay in this, but there is a workaround. If you attempt this, please be cautious because these are not typically expected to be user-facing changes. If you need assistance implementing this and your company has a paid license, please open a ticket with the Support team (Customer Portal)

1- Install the fonts with the commands below. Fonts are copied under /usr/share/fonts/truetype/msttcorefonts folder.

RUN apt-get update && apt-get install -y --no-install-recommends \ fontconfig cabextract xfonts-utils && \ echo "ttf-mscorefonts-installer msttcorefonts/accepted-mscorefonts-eula select true" | debconf-set-selections && \ apt-get install -y --no-install-recommends ttf-mscorefonts-installer && \ fc-cache -f && rm -rf /var/lib/apt/lists/* && \ apt-get install -y ca-certificates && \ update-ca-certificates && \ rm -rf /var/lib/apt/lists/*

2- On the executor the fontsfile is located at /home/knime/knime/plugins/org.eclipse.birt.report.engine.fonts_4.15.0.v202403260939/fontsConfig.xml

3- In this xml file there is a section called: . This section tells BIRT where to look for the fonts.

4- Then in the docker file (via the app, or manually) we can remove the original fontsConfig.xml and copy the new one (same original file with 1 extra line)

RUN rm /home/knime/knime/plugins/org.eclipse.birt.report.engine.fonts_4.15.0.v202403260939/fontsConfig.xml COPY fontsConfig.xml /home/knime/knime/plugins/org.eclipse.birt.report.engine.fonts_4.15.0.v202403260939/

5- Create the new docker image and verify that fonts work as expected.
