PrintContext.setCairoContext

void setCairoContext(cairo.context.Context cr, double dpiX, double dpiY)

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
