In C6, alot of the PDF output is called from a class which writes out the pdf, in C7 I think the report engine changed and it became an image file embedded in a pdf, which meant for me, URL links in the pdf no longer worked so I stuck with C6.
It’s a template option as to which behaviour it uses.
Go to the PDF extension in the report, General Tab, “Use Scan Copy Mode”.
If this is on then the PDF is generates as a collection of “images”. If it is off then it generates the PDF as text.
Scan Copy Mode is used (ie on) when you need to include something that the engine can’t do in text. Most commonly it’s used for including non-english characters.
