Dear all,
This may be specific to Mac, I haven't had a chance to test another
platform. Consider this,
plot(1,1,t="n")
rasterImage(matrix(1),1,1,1,1)
library(grid)
grid.rect(gp=gpar(fill="grey"))
The grid.rect covers the full device window as expected. However, when
I resize the window ever so slightly (interactive device) the rectGrob
is suddenly clipped to the previous plot window. I cannot understand
this behavior, and it doesn't happen if one removes the rasterImage()
call, so I suspect something iffy is going on with the display list or
something.
The only device I've tried is quartz(), x11() crashed with rasterImage,
*** caught segfault ***
address 0x28, cause 'memory not mapped'
Traceback:
