The output, written to [[$FG_HOME]]/Export/WholeCanvas.xml, would look like this: | |||

Do note that this is an entirely valid [[PropertyList]] encoded XML file, which means that it could be also used to unserialize the Canvas, i.e. reading it back into FG to create a new valid Canvas and display the texture there. The main limitation here being that this would be a "passive" Canvas only, without any listeners/timers etc being bound obviously, because just the visual aspects of the original Canvas texture would be re-created, but none of the logics used to originally create/animate the Canvas (think PFD, ND, CDU or Map): | |||
