On Linux the package “fontconfig” must be installed and accessible according to Package dependency “fontconfig”. For example, on Red Hat Linux with Internet access you can install “fontconfig” by executing the yum package manager:
yum install fontconfig
As an alternative, download the package into a custom directory and set the path to this directory via the ImageMaster option: ima.aspose.custom.fonts.directory
If this font package is missing, this can have multiple effects in a running environment:
-
Attachments (e.g. of the MIME type text/plain) cannot be displayed with the WorkplaceClient because the internal rendition service fails. Either a constantly rotating circle (busy icon) is shown instead of a thumbnail preview, or a message like the following is displayed in the WorkplaceClient:
“The attachment cannot be previewed: the conversion failed.” -
In parallel, INFO, and SEVERE messages like the following are created in the ImageMaster log file:
