Pdf generation when XML contains an attached image file fails in 2.9.0

Aspose.PDF Product Family
1

Hi,

I have a txt file which contains data in XML format. My requirement is to read this file and create a pdf.

Sample code :

Pdf pdf = new Pdf();

StringBuffer strBuff = getContentFromFile(); // This method reads the content of the file attached here

pdf.bindXML(new StringBufferInputStream(strBuff.toString()), null);

pdf.save("/usr/config/test/Aspose_Test_14.pdf");

If I am using Aspose 2.7.0 its working fine in both windows and Linux machine.

But in 2.9.0 this works fine in Windows machine and failing in Linux machine.

The file contains a piece of string :



In this line its throwing the following exception :

Exception Summary: Couldn't convert image stream: null
Exception Cause: null
The Exception stack trace is as follows,

If I remove that particular line then its working fine .

Hello Sriman,

Sorry for replying you late.

I am afraid I have not yet completed my testing over Linux environment because I have encountered some issues over my Linux instance. However I am trying my level best to get them fixed ASAP so that I can try replicating this scenario over it. Please spare us little more time. Please accept our humble apologies for the delay and inconvenience.

Hello Sriman,

Thanks for your patience.

I have further investigated this problem on Linux RedHat Enterprise 5 and I am able to notice the same Exception. However I am also unable to notice this problem on Windows Operating system. For the sake of correction, I have logged this problem as PDFJAVA-28967 in our issue tracking system.

Hey,

we have a release of our product on this 31st July. Could you please let me know when will this fix be available ?

This is working on 2.7.0 and its failing in the latest version 2.9.0 which should not be the case for a product like Aspose. Some extra fixes/functionalities should go with the latest releases and not SOME EXTRA ADDITIONAL BUGS.

We have further investigated this issue and have found that Aspose.Pdf for Java is working correctly over Ubuntu OS. Can you please share which version of Linux you are using ?

We are really sorry for the delay and inconvenience.

I have Linux machine with below configuration:

Linux 2.6.18 x86_64 GNU/Linux
