And it introduces a new one if I set the output to go to buffer:
IDL> display_diffs, names=['gfortran 4.4.6 PROD', 'baseline'], /png
..etc..
% Attempt to call undefined method: 'GRAPHICSBUFFER::SETCURRENT'.
% Execution halted at: DISPLAY_RESULT_DIFFERENCES 103
CRTM/branches/RB-2.1/src/Build/test/forward/display_diffs.pr o
% $MAIN$
So if you set the BUFFER keyword in the WINDOW() call, the method
SetCurrent becomes invalid for the graphics id.
So now I have to a
IF ( ~buffer ) THEN w.SetCurrent
before each FG call.
Wha...? I gotta be doing something wrong here.
cheers,
