Hitting a number of critical issues that are blocking us from releasing a product in the latest aspose.slides build. The attachments have out internal bug numbers in the filenames so as to pair them up with issues. _aspose.png files are output from aspose, while _ppt.png are output directly from ppt. Most are getThumbnail() and vector related.
1) images from getThumbnail() do not match ppt export - this is our internal bug number 3137
2) various vector graphics issues from getThumbnail() - in particular: clouds, arrows, etc. - our internal bug number: 3145 - i am still waiting on some more sample ppts from out qa that exemplify the issue, and will attach those as they become available
In addition we are still waiting for a fix for your issue id 12567 referenced in this thread.
These issues, and similar have been holding up a product release for us, so as soon as you can get us an estimate as to when we can expect fixes that would be great. Will update if i can pull together some additional sample data.
Thanks.
