Hi Andrew: The example 14 "misalignment issues" turned out to have nothing to do with multistream issues or extra M commands. Instead, I could reproduce the same issues with example 1 by specifying the same geometry externally for example 1 that is specified internally (500x410+100+2 for "master" and 500x410+650+20 for slave) in the example 14 case. Will you take a look at the following results for various geometry offsets for example 1, and let me know what you think? examples/c/x01c -dev psc -geometry 500x410 -o test1.psc examples/c/x01c -dev psc -geometry 500x410+100+20 -o test2.psc examples/c/x01c -dev psc -geometry 500x410+650+20 -o test3.psc I would like your take on the above results because of your knowledge of our ps and psttf device drivers, PostScript, and bounding box calculations. I suspect gv is having trouble displaying test2.psc and test3.psc because of bounding-box miscalculations by our ps and psttf device drivers when offsets are applied. If you agree, I hope you will be able to come up with a fix for both device drivers. Alan __________________________ Alan W.
