Rendering from pdf and saving as png

[bjcam]

Hi,
I have just upgraded from GdPicture.NET Document Imaging SDK v6 to v8.
In my application I load pdf files, render as image and save each page as .png
I can't see how to do that now because gdviewer.PdfRenderPageToGdPictureImage is no longer available in v8. I can display pdf from file but the only options to save the document are pdf, tif and jpg. PNG was the best format for me because of the small file size and rendering of black and white using grayscale.
How can I save a page of pdf as png in v8? How can I render pdf as an image?

Hi,

You have 2 options:

1- use the GetPageThumbnail function.
2- Use the GdPicturePDF plugin that includes all you need to rasterize PDF to bitmap.

Kind regards,

Thanks, Loic
Can you tell me if the pdf plugin has any annotation features or would I have to buy that separately too?

Hi,

The GdPicturePDF plugins has not yet annotation feature. We will bring support to add PDF annotation, by code very soon.

For interactive annotation support (annotation that can be drawn by user ), you should consider the GdPicture XMP/Annotations plugin that is a standalone plugin.

Kind regards,

Loïc

Hi
Yes, I am considering the annotations plug-in, but I wouldn't be able to buy both that and the pdf one.
Thanks for your help
