I'm not sure I followed:
I have a picture in CMYK (SWOP ICC), that's "deviceA". I want to
preview it on screen, *application* converts it to sRGB and sends this
3D data to Cairo. Then, Cairo converts it to the space of my monitor
("deviceB") and draws it.
It looks ok, so I want to export PDF - *application* converts my
picture to sRGB and Cairo converts it back to SWOP CMYK (because I
print in US on coated paper).
Is this what you said?
