I tried to reproduce this with the EPS file an gv alone. That did not work, i.e. it opens without delay. Unfortunately this now becomes groff dependent. But anyway it's also OpenBSD specific. I tried with http://www.openbsd.org/images/poster31.jpg:
jpegtopnm poster31.jpg > poster31.pnm pnmtops poster31.pnm > poster31.ps gv poster31.ps # -> opens at once File t.tr: .PSPIC poster31.ps troff -Tps t.tr|grops >t.ps gv t.ps # -> opens at once troff -Tps -dpaper=a4 t.tr|grops -pa4 >t.ps gv t.ps # -> opens very slow (15 seconds) Embedded in a real document it took about 40 seconds for a picture of that size. As mentioned in the previous mail there is no delay on e.g. Linux. --Carsten
