DOORS Next Generation does not show preview image of uploaded Excel spreadsheet with correct fonts
Accepted answer
There is a high chance for this to happen if your DOORS Next Generation server is on Linux.
The reason is that DOORS Next Generation server will only use the available fonts on the server to create preview images for uploaded Excel spreadsheets.
If the fonts used in Excel spreadsheet is not available, then substituted fonts will be used.
In Excel, the default font is Calibri.
On Linux, DOORS Next Generation server has only access to Lucida fonts in <JazzHome>/server/jre/lib/fonts directory.
DOORS Next Generation server will use Ludica fonts in place of Calibri fonts when generating preview images.
This will often cause texts not fit into cells.
To resolve this issue, copy Calibri fonts and other Windows fonts from c:\windows\fonts directory from a Windows machine to <JazzHome>/server/jre/lib/fonts directory of the Linux DOORS Next Generation server.
The fonts will be available immediately for DOORS Next Generation server to use to generate new preview images.
There is no need to restart DOORS Next Generation server.
The existing generated preview images will not be updated.
You will need to upload a new version (can be the same version as the uploaded one) to have the preview image updated with the correct fonts.
