Required X11 libraries for CentOS

Aspose.Total Product Family
1
Hello,

I am currently using following Aspose products.

aspose-words - 12.1.0
aspose-imaging - 2.1.0.0]
aspose-cells - 8.3.2
aspose.slides - 15.3.0
aspose-pdf - 9.7.1

I am planning to run these conversions in "CentOS release 6.7".

We have been getting few X11 errors depending on which conversion is being performed. I have listed some errors below.

Is there a list of required X11 libraries that need to be installed to run above Aspose products?

Thank You.

Hi Tashani,

Sorry, we were not able to reproduce this issue using the latest versions of these APIs. You are using very old versions of the APIs. Can you please test with the latest versions and share your complete code and the steps to reproduce the issue if the problem persists?

You can check license folder when you install any Aspose API to find a list of third party APIs used by the Aspose APIs.

Best Regards,

I downloaded all the new libraries. Only tried to convert a Word document. Here is the error:

options.setTiffCompression(TiffCompression.LZW);
doc.save(test.TIFF", options);

Hi Tashani,

During our initial investigation, we were not able to reproduce the issue. Can you please also share which Java version are you using and a sample document?

We used -Djava.awt.headless=true property and the conversions are working now. Thanks for looking into this.
