Summary: Image colors are inverted when printing a plot to a
file with FLTK
Project: GNU Octave
Submitted by: None
Submitted on: dom 13 apr 2014 12:09:42 UTC
Category: Plotting with OpenGL
Severity: 3 - Normal
Priority: 5 - Normal
Item Group: Incorrect Result
Status: None

Release: 3.8.1
Operating System: GNU/Linux
_______________________________________________________
Details:
The attached example contains code which:
0 shows a picture with _imshow_
0 plots some data over it in blue
0 displays the figure
0 saves the figure to a file
0 repeats the steps with GNUPlot
The figure display correctly on video, while the resulting output picture has
a "correct" blue line, but inverted colors. This happens *only with FLTK* on
my machine.
Expected result: I would expect to get a printed picture with correct colors,
like GNUPlot does.
