Hello,

The saveViewerOptimizedBuffer method requires a ViewerOptimizedOptions object to be passed in to the method. Please let me know if this works for you.

Hello,

Sorry I was trying to follow the documentation but I am struggling a bit here.
Here’s the code I tried, and result in ops.setMinimumInitialThumbnails is not a function error

      const ops = new PDFNet.PDFDoc.ViewerOptimizedOptions()
      console.log("ops??", ops)
      ops.setMinimumInitialThumbnails(1)
      console.log("ops??", ops)
      const buf = await finalDoc.saveViewerOptimizedBuffer(ops)

I think the main question is, is there a way for me to convert a PDFDoc to a buffer, without saving it to the memory? Thank you so much.

Thank you for your response. I noticed that you initially stated that you are running 9.1. Please note that this method is only available with the 9.2 release. Please upgrade and try running the code again.

If you are looking to save the document to a buffer, you can either use the saveViewerOptimizedBuffer method, or PDFDoc to a buffer, or you can use the saveMemoryBuffer().
