Save Cairo X11 Plot to File
Description
Save the current page of a cairo X11() device to a file.
Usage
savePlot(filename = paste("Rplot", type, sep="."),
type = c("png", "jpeg", "tiff", "bmp"),
device = dev.cur())
Arguments
- filename
- filename to save to.
- type
- file type: only
"png"will be accepted for cairo version 1.0. - device
- the device to save from.
Details
Only X11 devices of types "cairo" and "nbcairo" are supported.
This works by copying the image surface to a file. For PNG will always be a 24-bit per pixel PNG ‘DirectClass’ file, for JPEG the quality is 75% and for TIFF there is no compression.
At present the plot is saved after rendering onto the canvas (default opaque white), so for the default bg = "transparent" the effective background colour is the canvas colour.
Values
Invisible NULL.
Note
There is a similar function of the same name but more types for windows devices on Windows.
