I hope this question could be answered here.
I need to understand what values should be chosen for A2 size.
Per this Franklin Heath article and this one at Microsoft Answers:
A3 and A4 size are specified by microsoft PDF writer as
A3 : *PrintableArea: PAIR(5346000, 7560000)
A4 : *PrintableArea: PAIR(3780000, 5346000)
With that I am not able to figure out the A2 size
Stephen Wiltshire specifies A2, A3 and A4 as
The A2 size print measures 42.0 x 59.4cm, 16.53 x 23.39 inches, if
mounted 59.4 x 76.6cm, 23.39 x 30.16 inches.
The A3 size print measures 29.7 x 42.0cm, 11.69 x 16.53 inches, if
mounted 40.6 x 50.8cm, 15.98 x 20 inches.
The A4 size print measures 21.0 x 29.7cm, 8.27 x 11.69 inches, if
mounted 30.3 x 40.6cm, 11.93 x 15.98 inches.
I am not able to figure out what unit the values are in the gpd file
