Hello all,

there's a patch for the G-code exporter available which replaces the 
definition of the board size.

Currently, there are these two values (Width, Height) in the preferences 
dialog. At the same time, a board shape shall be defined by the outline 
layer. IMHO, this situation is a bit contradicting in its self.

The new solution for the G-code exporter whould be to walk through each 
track of the outline layer to find the minimum and maximum extents. 
Looks more reasonable to my understanding and whould make the values in 
the preferences dialog obsolete (except, perhaps, for internal 
calculations, which should be hidden).

My question now is, whould calculating the board size dynamically be a 
good solution for the entire application? Users whould resize the board 
by just moving the tracks on the outline layer and these two preferences 
items could (eventually) go away. I'd prefer to work on a general 
solution instead of bringing in custom stuff for just this exporter.

Opinions are welcome as much as hints on where/how a general solutuion 
should be coded.


Markus
