[Powerpoint] Action button shape was converted to a white box

[Charlotte Lai]

Dear Sir / Madam

We have tried to open and save a powerpoint presentation with the Shape - "Action Buttons: Forward or Next", and found that the action button was converted to a white box, do know how we can preserve the action button shape?

The sample code and powerpoint was attached for your investigation.
Thank you for your help in advance!

Version used: Syncfusion.Presentation.AspNet (Version: 16.4.0.52)


using (MemoryStream memStreamPPT = new MemoryStream())
using (MemoryStream memStreamPPTAdmin = new MemoryStream())
{
memStreamPPT.Write(pptData, 0, pptData.Length);
memStreamPPT.Position = 0;

Syncfusion.Presentation.IPresentation pptxDoc = Syncfusion.Presentation.Presentation.Open(memStreamPPT);

pptxDoc.Save(memStreamPPTAdmin);
pptxDoc.Close();
memStreamPPTAdmin.Position = 0;

byte[] pptDataAdminModified = memStreamPPTAdmin.ToArray();
return pptDataAdminModified;
}

Dear Manikandan,

Thank you for your prompt reply, our requirement is to save the Presentation document with action buttons only.

Do you know if there are any workaround to preserve the action button in the mean time?

Charlotte

Hi Charlotte,

Thank you your update.

As mentioned earlier, Essential Presentation library doesn’t have a support to preserve Action button shapes while saving the Presentation document.

As a workaround solution, we suggest you to save the action button as picture in Microsoft PowerPoint and insert the saved picture into PowerPoint document, which will be preserved properly while resaving the presentation document.

Please share the below link for more details,

Please find the Presentation document which have action button shapes as picture.
