Hi there!
I'm going to take out my life if I don't generate a 126x126 mm today :S
I'm trying this during days. I have summerized my application in a main
(It can be usefull to everyone who is not looking for an specific size)
I create a 126 x 126 mm, inside this I put a pdfTemplate wich is 126 x 126
too. Then, inside this one I put many other pdfTemplates as Image Regions
and
inside every ImageRegion I draw an 180 dpiImage. I use this hierarchy cause
I can crop, put borders and things like that using the view of a
pdfTemplate.
Well, The pdf result is 44,4 x 44,4 mm :( Why?
Here is the code.
(I know I don't need too many imports :p)
