I’m using aspose-cells 17.9 (java) and I’m experiencing images stretching when converting to PDF. I’ve put together a project on Bitbucket to demonstrate the issue. The project can be cloned here: https://bitbucket.org/BobReed1331/asposesupportrequests
There is one branch in the project and executing AsposeCellsConverterTest.java will create an output file called Excel_File_CONVERTED.pdf. The problem can be found on the second page of the output file. There is a comment in the test file explaining the issue further.
I look forward to your response.
