Problem changing Y coordinates

[cmaremail-pdfbox]

Hi all,

I'm developing a software tool to adapt PDF documents.

The idea is to copy all visible elements (text, images, etc.) from a source 
document to a new document (destination) with a different page height than the 
original one.

For each visible element in the source document, how can I get its Y coordinate 
and set a different Y coordinate in the destination document?

For now, I've implemented a prototype by modifying PrintImageLocations.java and 
PrintTextLocations.java, but this approach seems too complicated for a simple 
copy.

Thanks in advance.
