Thank you, but I found a way using findImages then selecting the image and then accessing to imagetype etc.
 
But I'm experiencing another problem during extraction. I'll open a new post about this.
 
thanks

Hi!

As far as i know the first three properties are image-relevant and you can get them only searching directly into the code. That's possible... first unencrypt and save with QuickPDF and then looking with the your programming language. A decrypted pdf is nearly ascii - so looking inside is possible.
Please read the thread "he first steps..." in the "General section"...

Cheers and welcome here,
Ingo

Hi again,

I need to get page information for (scanned) pdf file like:
pagetype: tiff, jpeg etc.
colour: BW or colour
resolution: in DPI
compression: compression used for the page
 
but as I open my file with:
       qp.LoadFromFile(CurrentFilename)
when I call:
      qp.ImageHorizontalResolution
or
       qp.ImageResolutionUnits
 
it returns always a 0.
 
How can I achieve this?? Any help is appreciated (vb, C#)
 
Thanks in advance
 
Sly
