Hello,
We are using aspose-slides-cpp-windows-25.4 version to convert a power point to HTML5. We then use converted HTML5 in our application for display. It works good for most pptx files, but it is not converting one PPTX file properly. I am attaching a image of PPTX which has this conversion issue. Could you please check what could be the issue with this? PPTX gets converted but all the boxes in the image are overlapped

It appears you are encountering issues with converting a PPTX file to HTML5 using Aspose.Slides for C++. This can occur due to various factors, such as unsupported features in the PPTX file or specific content that the conversion process cannot handle.

To troubleshoot this issue, consider the following steps:

  1. Check for Unsupported Features: Inspect the PPTX file for complex elements (such as animations, transitions, or unsupported media) that may not be fully supported in the HTML5 output.

  2. Update Aspose.Slides: Ensure you are using the latest version of Aspose.Slides for C++. Newer versions may include bug fixes or enhancements that could resolve your issue.

  3. Simplify the PPTX File: If feasible, simplify the problematic PPTX file by removing complex elements or dividing it into smaller sections to identify the specific cause of the conversion issue.

  4. Use Alternative Formats: If the HTML5 output is not satisfactory, consider converting the PPTX to another format (such as PDF) before converting it to HTML5, as this may yield better results.

If the problem persists, consider reaching out to the Aspose support forum with detailed information about the PPTX file and the issues you are experiencing for more targeted assistance.
