I've downloaded the whole library and replaced the old one on my computer. My computer runs Mac OS X 10.8.5. I've restarted idl and the whole computer also!
The funny thing is that almost every time i run the cgimage command i get a different axis color.
Also, If i run create a cgdispaly window it resolves partly the problem
So, this code:
!p.multi=[0,5,5]
cgdisplay, 600,400
for i=0,24 do cgimage, im,xv=x,yv=x,/axis
!p.multi=0
creates a series of plots where the first 4 plots have black axis and the rest have white axis.
This code, on the other hand,
!p.multi=[0,5,5]
for i=0,24 do cgimage, im,xv=x,yv=x,/axis
!p.multi=0
creates axis with all sorts of different colors. And the colors change randomly every time i run the for loop!
Also, when i tried to take a snapshot
snap=cgSnapshot(file='snaphot.png')
The resulting png file have colored vertical bars, like an old television that can't get signal..
What have i done??
