generated images are truncated!

Hello,

am using the following two codes to generate process diagrams, but the result is same and the out put image is truncated:

http://postimg.org/image/5ul769n7x/

            
final InputStream definitionImageStream = repositoryService.getResourceAsStream(processDefinition.getDeploymentId(), processDefinition.getDiagramResourceName());

String imageExtension = extractImageExtension(processDefinition.getDiagramResourceName());

String fileName = UUID.randomUUID() + "." + imageExtension;
File downloadsTmp = new File(downloadsPath);
FileManagmentHelper.writeFileFromStream(definitionImageStream, new File(downloadsTmp, fileName));
‍‍‍‍‍‍‍‍‍

            final InputStream definitionImageStream = repositoryService.getResourceAsStream(processDefinition.getDeploymentId(), processDefinition.getDiagramResourceName());

            String imageExtension = extractImageExtension(processDefinition.getDiagramResourceName());

            String fileName = UUID.randomUUID() + "." + imageExtension;
            File downloadsTmp = new File(downloadsPath);
            FileManagmentHelper.writeFileFromStream(definitionImageStream, new File(downloadsTmp, fileName));

Did the Activiti Engine generate these images, or did you upload an image when you deployed the process definition?
Can you share the process definition XML so I can give it a try on my local machine?

Thanks,
