Hi tianliang
welcome here
 You must verify the returned value form to LoadFromFile function.
If QuickPdf can't load the file (LoadFromFile return a zéro), the rendering is a blanck file.
Can you make a link to your file , as we can have a look on it ?

Hi tianliang
This file contain JBIG2 pictures and, at the momment, QuickPdf can't handle them. I know that QuickPdf team is studying this. Edited by DELBEKE - 28 Mar 09 at 5:35AM |
