Keep ximtool readable in 8-bit color

p>Phil Massey at Lowell Observatory sent in the following tip:

p>This probably doesn’t concern you, since it sounds like you use DS9, but I’m a fan of ximtool (actually ximtool-alt)—so easy to register frames against each other—so I’m willing to go to 8-bit color until Mike Fitzpatrick eventually fixes ximtool so it works under 32-bit.

<

p>However, when I set the color to 8-bit and do an implot, the graphics window is generally totally unreadable—yellow on white background.

<

p>I did eventually find a fix to this, and I don’t know if it would be worth posting on your web site or not. It turns out that there was nothing like an .Xdefaults being loaded. So, I created one:

        Gtermcolor0:          black
        Gtermcolor1:          ivory
        Gtermcolor2:          red
        Gtermcolor3:          green
        Gtermcolor4:          blue
        Gtermcolor5:          cyan
        Gtermcolor6:          yellow
        Gtermcolor7:          purple
        Gtermcolor8:          magenta
        Gtermcolor9:          black

<

p>based upon a note I’d gotten from Mike when I’d encountered a simialr problem some years back. and then explictly put in my .xinitrc file,

xrdb -load ~/.Xdefaults

<

p>prior to starting up any windows or the window manager.

<

p>This tip sounds like it is to keep xgterm plots looking correct. Over on the x11iraf page, I make a tip on how to keep everything looking ok when you use ximtool to display a graphic, which is to use the -maxColors flag in ximtool to limit how many colors it grabs.
