Hi,
I'm using Debenu PDF library to convert PDF into PNG image by calling RenderPageToString from my code. Everything is working fine apart from a specific PDF which contains transparent image, which is rendered with a black background. What could be done in this case? regards

And did you try to use current release with trial license key ?
If I remember well, there was some issues with printing, so maybe this is now fixed.

Hi,
it's right: 11.13 and 11.14 offers two png-fixes but ... How the Images can be built depends on how the pdf is structured and which elements were used to do it. Perhaps you can upload your relevant pdf anywhere online and post the link here? So we can try yourself and if we're making the same experiences you should post your Problem to the official Debenu support page. |
