I have installed hexsticker on my machine currently using R41. I have been trying to create sticker using the example sticker and i get this error:

Error in png_dev(..., res = dpi, units = "in") :
unused arguments (type = "cairo-png", antialias = "subpixel")

I started trying it while using R40. What is the error and how can it be fixed?

I have re-installed hexsticker using the dev version and also re-installed cairo, cairodevice
