Dear yangjuncn,

Thanks for waiting.
Considering your urgent situation, here is a temporary hotfix.
https://www.e-iceblue.com/downloads/Tem ... _4.8.9.zip
Since the fonts in your PDF are specific and different, when converting you need to use different code. As for the file "031001700112_04768983.pdf", please use the code "Image image = doc.SaveAsImage(indexPage, dpi, dpi,true)". For the file "031001700411_37099943.pdf", please use the code "doc.SaveAsImage(indexPage, dpi, dpi)".
Any question, welcome to get it back to us.

Sincerely,
