AdobeForms resize PDF before merging, or convert PDF to image

[patrick_weber11]

Hi community,

is there a way to resize a given PDF document into another paper format?
Alternatively, does someone know a way to convert a given PDF into an image format like tif or jpeg?

Background:
we print some PDF documents (pp order related) and print some drawings of the part on the 2nd page. In past, these drawings has been stored in KPRO as tif document and the image was printed with an image container in ADS.
Now they have been changed and are stored as PDF now. I was able to merge the newly created pdf (pp order document) with the existing drawing (PDF in KPRO) into one PDF document. But now I observed that the drawing uses a different paper format (DIN A2) whereas we print it as DIN-A4, which is 4 times smaller.

This causes two issues:
1. as the merged PDF now uses different paper formats, it is one spool file but gets processed as different files by the printer. So the drawing is no longer on the 2nd page of the same sheet of paper (back side, duplex print).
2. as the paper format doesn't match provided paper format of printer (A4 only), only a part of the drawing gets printed (upper left corner)

Question

Does someone know a way to resize an existing PDF document in ABAP? The previously used image was automatically scaled down by ADS to fit into the image frame.

Or does someone know a way to convert a given PDF file to an image format like tif or jpeg in ABAP? This way, ADS will scale the image as it did before.

When you merge the two PDFs, do you call a printer? And does that printer have specific settings for the page size?

Yes, after merge I send the file to a printer. It's a common A4 duplex printer with just one paper size. There are no further settings as far as I know.

What I had in mind is whether you do something like this: https://blogs.sap.com/2017/07/21/merge-multiple-adobe-forms-into-1-pdf-content/ when you merge the two pdf files. I am thinking that if you use a similar approach you may be able to resize the shape pdf utilising the printer's settings to make them DINA4 at the time of the merge.
