I have two PDF files, when I render them using DEBENU API: QP.RenderPageToFile(50,1,0,"pdfimage.bmp"); , it creates empty BMP file, with out any picture in it. They are single paged PDF files, and its size:17 MB, 19 MB respectively.

When it is rendered with DPI Value=100, it generates blank white image with dimension: 5284 x 3311, and its bitmap depth is : 24.

Same PDF file, when it is viewed using Adobe Reader, it displays the picture with good quality.

Are there any alternative ways, to get picture using DEBENU API.

I am using DEBENU 12.11 version, and the tool is integrated with WIN32 API and C++.

 

if the dimensions are as large as described i would try a another image-format to save storage.

Please read here about gdi+ and other render engines (is gdi+ on your system?):

Here is a "how to" from the Debenu-kb:

Here is a render sample with scaling (good if you have large images as described):

This isn't exactly for your problem but it will help, too:

You should check always the returning values from the functions to determine where's the problem.

Good luck ;-)

BTW: I've got this all from the debenu support pages - you should be able to do this by your own ;-)

Thanks for the information. It was useful. I could able to fix the rendering issue.
