Hello,
Apologies up front, since this is only peripherally related to LAM.
I have very much enjoyed using xmtv. The default colormap, though, is
distracting for my purposes. I would like to force xmtv to use grayscale.
So, being ignorant of X, I inflicted the following on xmtv.c.
#if 1
XrmValue source, dest;
Visual v;
source.size = strlen("StaticGray") + 1;
source.addr = "StaticGray";
dest.size = sizeof v;
dest.addr = &v;
XtConvertAndStore(w2, XtRString, &source, XtRVisual, &dest);
#endif
XtVaSetValues(w2,
XmNtopAttachment, XmATTACH_WIDGET,
XmNtopWidget, w1,
XmNbottomAttachment, XmATTACH_FORM,
XmNleftAttachment, XmATTACH_FORM,
XmNrightAttachment, XmATTACH_FORM,
#if 1
XtNvisual, &v,
#endif
NULL);
Of course it doesn't do near what I hoped for. After executing xmtv, I get
the following diagnostic on stdout:
Warning: Cannot find Visual of class StaticGray for display
localhost:10.0
This occurs for an XtNvisual of "GrayScale" as well.
Can anyone offer pointers on where to go next? Perhaps the problem resides
more in the server than the above code. I think this unlikely, since other
imaging applications display gray very well on the same server.
Thanks,
Vince Virgilio
