In article <124730@sun.Eng.Sun.COM> dmc@sun.UUCP (Doug Cook) answers my
questions about Xview.

Ok, but memory pixrects (rather than server images) are useful because
(as it says in the memvar.h supplied with XView) they permit "more direct
access to the image" (than general pixrectops, but also than server 
images).  It would be handy if someone were to produce a portable 
memory pixrect library.

Good!  The manuals are pretty useless when you can't use the index.

Thanks for the prompt response.
