"...by exporting PDF pages as image then add that images to Word Document..."
Thank you for fast response!
The approach you describe is using images. This does not work on our site. We are using Syncfusion libraries currently as a pre-processing step to generate documents that can be read and interpreted by an API to extract data from the results. So using images would lead us to use OCR on top. And that is something we would like to avoid.
Meanwhile I was trying out a different approach:
I found the OPX example (https://www.syncfusion.com/products/opx/xpdf) where you converted a PDF into HTML. My idea is, that it could be a workaround to use this aproach and finally generate a WordDocument from the HTML output. Unfortunately there is no possibility to use streams or byte arrays using the XPDF lib with the wrapper you provide. It can only take paths. Furthermore it's a not ideal that there is no nuget package available so I had to grab the DLLs from the example manually.
So there is still no solution to this issue.
Help is appreciated!
