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.
