Hmm. I've personally used a tool called pdftk for manipulating PDFs - but it
was at least time consuming to install on Arch Linux but that's what we love
Arch for, isn't it? :-) Anyway, seems that it's not suitable for your purpose
and I see a pure Gambas way, too:
- Instantiate a new Image[], named myNewPdfImages, which will contain your
new annotated pages as Image objects;
- Define some Annotate() method (just for the purpose of this algorithm)
which takes a pristine Image, annotates (using Paint) and then returns it;
- Use gb.pdf. Load your PDF and loop through the pages:
For iInd = 0 To myPdf.Count - 1
myNewPdfImages[iInd] = Annotate(myPdf[iInd].GetImage())
Next
The key is myPdf[iInd].GetImage() to get an image of the iInd-th page;
- Now use gb.cairo or the like to coalesce your new Images into a new PDF.
Nice application by the way. I can't wait to write it myself :-)
Regards,
Tobi
