@paulpan,

I did test your scenario/ case a bit by converting your template XLSM file to PDF (os:Windows 8, JDK1.7/1.8, etc.) to PDF using our latest version/fix (Aspose.Cells for Java v20.10.x - please try it), it works fine and PDF file is generated fine. We recommend you to kindly try using our latest version (if possible) if it makes any difference.

Moreover, it seems you are using some non Windows os where you might be using open jdk. The issue you mentioned might be due to open jdk, so you may try to use Java (jdk/sdk) if it works in your environment? Also could you provide us your environment details, we will check it further.

My environment :
openJDK 1.8,os:Centos7,Aspose.Cells for Java v20.60
With v20.10 I get again the similar exception:

Thank you !

@paulpan,
As shared by @Amjad_Sahi, please try this scenario using the latest version Aspose.Cells for Java 20.10 and provide the feedback. As per policy here at Aspose, we test and rectify issues using the latest versions only.

Now I change to v20.10 and I get again the similar exception:

@paulpan,
Could you try to install “ImageMagick” on your environment?
Here is a similar issue: https://forum.aspose.com/t/aspose-cells-for-java-pdf/220423/3 which was resolved by installing “ImageMagick”.

Let us know your feedback.

@ahsaniqbalsidiqui
@Amjad_Sahi
This https://forum.aspose.com/t/aspose-cells-for-java-pdf/220423/3 is private.
And we find when we remove all images it will be ok.
Now I install “ImageMagick” and I get again the other exception:

@paulpan,
Its ok if that is private. We quoted it for reference that similar issue was resolved.

Please try the following code with Aspose.Cells API:

	java.awt.Font font1 = new java.awt.Font("SansSerif", java.awt.Font.PLAIN, 10);
	java.awt.Font font2 = new java.awt.Font("Serif", java.awt.Font.PLAIN, 10);		
            java.awt.Font font3 = new java.awt.Font("Monospaced", java.awt.Font.PLAIN,10);

	java.awt.Container container = new java.awt.Container();

To see whether the exception still occurs. Also, it seems that it is the issue of your environment: https://github.com/AdoptOpenJDK/openjdk-build/issues/693

after looking though the link, it seems that you need to install ‘fontconfig’.

Let us know your feedback.

Now I install “urw-fonts,fontconfig” and I get again the same exception:
