Hi,
I have tried already the same way which you have mentioned in your last mail.
I would like to tell you that ppt is working fin as per our expectaions but there are lot of issues for pptx.
I am able to generate images from pptx format without any issue if i set thumbnail size by default meeans (1,1)...................but if increase the height and width the generated images gets destored means background of text box location is somewhere and text is somewhere .
Please consider this as high priority,because we are planning to purchase your lisence by the end of this month .But these are the some issues in pptx format that we need to fix before purchasing ur lisence and our target date is end of this month.
I am attaching screen shot which will help you to understand exact problem.
You can find pptx file and generated images folder.
Thanks a lot for ur quick response.
