Hi.

PB doesn't offer such a functionality. The only thing that you can extract currently (in PB 2022 R2) from PDF's is attachments. But you can use third party tools to do that.

1) As far as I Know Image Magick can do that... It's a command line tool, so it will be easy to use it. Google can help you (pdf generation - Convert PDF to PNG using ImageMagick - Stack Overflow).

2) Pdf Creator can do that. You must check licensing.

3) You can use iText (itextsharp) to manipulate any pdf. It has support for .net, I guess (but never tried) it can work with snapdevelop. You must check licensing.

In older versions of pdf creator (1.6.x+), there was a library called pdfforge.dll based on itextsharp that has an ExtractImages method. Pdfforge.dll is built to be used in .net, but is also com visible, so you can register it and directly call it from pb. Again you have to check licensing and I'm not sure if you can find those old versions on the net.

Andreas.

ImageMagick also has a .NET Wrapper: https://github.com/dlemstra/Magick.NET so there's that option as well

Hi Zhang;

  I just started working with this App a few weeks ago for PDF manipulation.

Its free & open source. I do not have a lot of experience with it yet but maybe, this can do what you need ...
