Assuming by “resolution” you mean “pixel density” rather than
“image dimensions”, this only matters for image surfaces, since other
surface types like SVG, PDF and PostScript are resolution-independent.

Cairo doesn’t have any way that I can think of to specify the pixel
density for an image surface. That would be up to the separate library
you use to write those pixels to an appropriate image-file format.
