I have a pptx file including an Excel workbook (a table, directly visible as a preview picture) :
- With Aspose.Slides 20.1 I am able to access to the EmbeddedFileData of the Excel workbook and to load them as an Aspose.Cells workbook.
- Then I am able with Aspose.Cells 20.1 to change texte inside the workbook and with Aspose.Slides to replace the original ObjectData (Excel workbook in the pptx file) by the data of the modified workbook.
- After saving the pptx file with Aspose.Slides when I open the file with PowerPoint the preview picture of the included Excel is still the one corresponding to original data
- If I open the Excel file included in the pptx file I can see the modified data and the preview picture is updated by PowerPoint, reflecting the new data
Is there a way to update the preview picture with Aspose.Slides before saving the pptx ?
