Create an NSBitmapImageRep with the appropriate properties. Create an NSGraphicsContext from that bitmap image rep using +[NSGraphicsContext graphicsContextWithBitmapImageRep:]. Make that graphics context current. Draw the image. Flush and restore the graphics context. Get the data from the bitmap image rep in an image file format using -representationUsingType:properties: or (if you really want TIFF) -TIFFRepresentationUsingCompression:factor:.
