Im developing a pdf viewer , but I cant extract pages as JPEG from XFA files. As In your c# sample i used below method byte[] bitmapData = (byte[])qp.DARenderPageToString(fileHandle,pageReference, 0, smallestDPI); but it doesn’t render my XFA pdf file as jpeg. Are there any methods in this DLL which I can use for my viwer ?  Edited by RVN - 11 Aug 11 at 6:31AM |

We don't render XFA files if they use XML data for the drawing commands. Most normal PDF files put PDF commands into the /Page /Contents stream. Some XFA fields have 0 bytes in this content stream entry and place the drawing instructions into the an XML stream.
There are very few PDF libraries that can process and render these XML based XFA forms. Can you send us the PDF file and we can check it out to see what type of XFA file it is. You can create a support ticket at Andrew. |
