[Octave-bug-tracker] [bug #52940] Regression with "PaperPosition" and printing

[Rik]

Follow-up Comment #26, bug #52940 (project octave):

If you want to experiment with an out-of-band communication protocol you could
use the hidden figure property __guidata__ which is normally used to implement
the guidata() function.

In libinterp/corefcn/graphics.in.h:3173


      any_property __guidata__ h , Matrix ()


To pass data,


set (gcf, "__guidata__", [0, 0, 1200, 800])


If this eventually works we could add a hidden property just for printing such
as __canvas_size__.  Although my guess is that in the long term we might want
to convert any calculations of size in to a C++ function and make that
available to m-files if *they* really need it.
