Subject: [Rd] strange interaction between rasterImage and Grid graphics
Message-ID: <AANLkTimX=5B478CCrEjCX0Y0Kw-FVuu=6ED5kYQ0iykY@mail.gmail.com>

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:
 1: rasterImage(matrix(1), 1, 1, 1, 1)
