setCairoContext
open fun setCairoContext(cr: <Error class: unknown class>, dpiX: <Error class: unknown class>, dpiY: <Error class: unknown class>)(source)
Sets a new cairo context on a print context.
This function is intended to be used when implementing an internal print preview, it is not needed for printing, since GTK itself creates a suitable cairo context in that case.
Parameters
cr
the cairo context
dpiX
the horizontal resolution to use with @cr
dpiY
the vertical resolution to use with @cr
