Hi,

I have tried your code here and it worked like a charm.
Since you have tried V9, it means you can have an SLA plan. Please submit a ticket to our support system: support.gdpicture.com, and attach a pdf to it that causes the error.

hi,
i tried the pdf that available in your document section with this name "GdPicture_NET Document Imaging SDK"

one thing very first time when i run the project i got error "GdPicture.NET.9.image.gdimgplug dll not found.." then i change my project setting "target CPU" option from any cpu to x86 and copy this dll to application directory then error get resolve i dont know just guessing that may be the error cause due to this .dll i m sure ...

hi,
if i run sample project everything works fine ,i got image id grater then 0 and get image , i think its issue related to dll .
in my project ,i had done following steps

1 i create a new project in vs 2010 and
2. add gdpicture.net.9 dll from "C:\Windows\assembly\GAC_MSIL\GdPicture.NET.9\9.0.0.7__3474f1a1ac699f44\GdPicture.NET.9.dll", ( as i saw this path in sample project)
3. copy GdPicture.NET.9.image.gdimgplug dll from "C:\Program Files\GdPicture.NET 9\Redist\" to application directory

also how do i use SetTransparency method to get transparent image from pdf page

Hi,

Please look at our sample demos, you also have add the GdPicture.NET.9.pdf.dll to the list of references.
There are also many c++ dlls that you need next to your exe folder: to understand what they are, look at the Redistribition section in our documentation.

As for set transparency, after you get the image from the pdf, convert it to 32 bits per pixel, and then set the transperncy.
