dev.capture
captures the current contents of a graphics device
as a raster (bitmap) image.
dev.capture(native = FALSE)
Logical. If FALSE
the result is a matrix of R
color names, if TRUE
the output is returned as a
nativeRaster
object which is more efficient for plotting, but
not portable.
NULL
if the device does not support capture, otherwise a
matrix of color names (for native = FALSE
) or a
nativeRaster
object (for native = TRUE
).
Not all devices support capture of the output as raster bitmaps. Typically, only image-based devices do and even not all of them.
