Folks,
I am having a problem with color display on my Macintosh from IDL clients
plotting to the X device. The symptom is that a graphics window is
created with the correct colors, but after clicking in another window and then
clicking back in the graphics window, the colors are changed. In particular a
plot written as white on black, often turns all black which makes it a little
hard to see ;-) Plotting to the same window again repeats the pattern. Other
X clients like xv don't have this behavior. Running IDL native on the Mac also
doesn't have this problem.
My configuration:
clients: IDL 4.0.1b (SunOS and OpenVMS, same behavior)
server: White Pine eXodus 6.0, running on a Power Mac 7200
settings: Backing store support: Use When Mapped
Colors: 256
Color Matching Tolerance: (Normal, Exact, Tolerant -- all NG)
display: Monitor Control Panel set to 256 colors
Output of help /device:
Current graphics device: X
Server: X11.0, eXodusPowerPC 6.0
Display Depth, Size: 8 bits (1024, 748)
Visual Class: PseudoColor (3)
Bits Per RGB: 8
Physical Color Map Entries (Used / Total): 64/256
Colormap: Shared, 64 colors. Translation table: Enabled
Graphics pixels: Combined. Dither method: Ordered
Write Mask: 255
Graphics Function: 3 (copy)
Default Backing Store: Req from Server
Window Status:
0: Win(640, 512, Req from Server)
Is this an IDL problem, a White Pine problem or operator error?
Thanks for any help.
