PPT to PPT: Conversion Throws ArgumentException

Aspose.Slides Product Family
, ,
#1

Hi,

I am writing to you about a problem we encountered in working with MSO PowerPoint document using the Aspose Slides for Java library (v21.10). Specifically, when we load the PP document and then save it (immediately, without any changes) to PPTX format it works fine, but when we try to save it to PPT format an ArgumentException is thrown.

We reproduce this issue on Ubuntu 18.04.6 LTS and OpenJDK 11.

I am enclosing the zip file with test code, as well as the source PP file.

In the hope that together we will quickly overcome the problem!
Best regards!

Nenad

@zpredojevic,
Thank you for contacting support.

Unfortunately, I was unable to reproduce the error you described. Please double check your results carefully (it looks like the presentation file is the same as here).

When the code sample attached when creating the topic (text code.txt) is run, the AssertionError generate the following stack trace: 2788.png (145.8 KB)

@zpredojevic,
Please check that presentation and code example. They are the same. Conversion is done without exceptions but the content is incorrect.

You’re right. By mistake, I uploaded an attachment intended for another issue. This is the correct attachment.
I apologize for the misunderstanding.

A short update, which can be helpful. In version 21.11 this problem as reported is not reproduced (it can be done save in ppt format), however another one is present. Content is lost on certain slides of target presetation, after the save operation in ppt format.

@zpredojevic,
Thank you for the additional information. Could you please highlight on screenshots what content is lost after the operation of saving on your end?

Here are the screenshots. Specifically, we are talking about slides 14, 20, 22 and 23. The first (14) shows that the content is not identical, while the others (20, 22, 23) does not contain any content.
