Subject: d.frame at parameter usageHello,
I am trying to set up a monitor ( like x1 ) with frames
from a script. I have tried doing d.frame commands as follows.
I interactively did d.mon and dragged the window up to cover
most of the screen, with the mouse. I then tried to give the following
statements either in a script, or manually, in the same form, i.e. each
on its own single line.
d.frame -c frame=full_screen at=1,679,1,961
d.frame -c frame=title1 at=275,320,1,295
d.frame -c frame=title2 at=320,365,1,295
d.frame -c frame=legend at=365,679,1,295
and I get errors on the at parameter. Why?
It looks to me the problem is that the "at" parameters are meant to
be in percent of the monitor length/width. Therefore, the maximum
values should be 100; not 275,679, et cetera.
Also, I wouldn't use the name "full_screen" since it is the
name used by default for the base screen of the monitor. Sometimes
this is handy to use as is. However, I doubt using it will blow
things up.
Also, is there a way to get the d.mon provided window sized
automatically, i.e. without benefit of mouse interaction?
With the Sunview graphics driver I used to set GRASS_WIDTH and
GRASS_HEIGHT environment variables to screen pixel values to
control the size upon invocation by d.mon. This seems to
be ignored by the X graphics driver. I haven't dug any deeper
to see if there is a quick change that could be made in the
driver, or if it looks for vars with different names.
Maybe someone else knows this...
Thanks,
Joe Vaughan
