I'm using mtext() to annotate a plot. I would like, if possible, to have
the individual characters formatted with an outline or border, with a
contrasting fill color inside the borders.
I'd appreciate suggestions or pointers toward a way to do this.
The reason is because I'm creating a graphic with a transparent
background
[png(filename,bg='transparent')] that is to be overlaid on Google Earth.
The background at my location of interest is so varied in color and
shape
that it is difficult to find a text color that will reliably have enough
contrast to be legible. Google appears to have dealt with this by using
white text with a black border on each character,and I would like to do
the same, if possible.
I have done some searching, without success so far. Admittedly, this is
well outside the scope of what R is designed for, but, hey, R can do
everything, so why not this? I did find a possible alternative, the
textrect() function in the RPMG package.
Thanks
