Error loading shared library libfreetype.so.6

[ledgerrunpeterzhou]

We are using the following spire.xls for java version:

<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.xls</artifactId>
<version>5.5.0</version>
</dependency>

and using openjdk:17-alpine to build our docker image. When we run codes to convert excel file to PDF, we encountered the following exception. Looks we are missing certain libraries in our docker image. Can you advise what libraries we are missing or what is the best way to resolve the issue?

Here is the exception details:

Hello,

Thanks for your inquiry.

From the error message I can't find anything directly related to our product. So at the moment, it is difficult to know the specific cause of this problem.
But I noticed that the version of Spire.Xls For Java which you are using is not the latest version. So I suggest you first try to upgrade to the latest version (12.6.0) and test again. If the problem persists, please provide your dockerfile so we can reproduce the problem. Thanks in advance.
