set_cairo_context

Description:

public void set_cairo_context (Context cr, double dpi_x, double dpi_y)

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:

this	a `GtkPrintContext`
cr	the cairo context
dpi_x	the horizontal resolution to use with `cr`
dpi_y	the vertical resolution to use with `cr`
