Thank You all, I did try this Bruce, with opacity 0 there is just blank page left. I agree, this could be done by customising map structure, but there is need for this for 88 km long cave system gradually discovered during 120 years. I´d like to make a video of discovery progress by each year in Demänovské Caves, so it should contain ~100 variations of the overall map... And sorry for spam, my mailing server seemed to not working properly, so I thought my e-mails didn´t pass through. Pavel Dňa 2024-08-06 21:44 Bruce Mutton napísal(a):
Just a guess. Try... transparency on opacity 0
This may make the white passage invisible, but may also make underlying passages appear to be on top. I used to emulate what Pavel is trying to do using purpose-built map definitions, but that is labour intensive. Interested to see if lookups can be made to do this. Bruce

Hi,
do you see a way how to avoid certain scrap representation (by transparent imprint) in pdf as overlaying part of cave while using lookup (explo-date), as can be seen in the middle of map explo-date_1978.pdf?
explo-date_2024.pdf represents the whole cave, in blue is a cave passage discovered in 2024, which is overlaying discovery from 1978.
My point is to be able to show the cave as it was known before newest discovery, without signs of newer parts...
Lookup is following:
lookup explo-date -title "Postup objavných prác" [0.1.1 1977.12.31] [0 0 0 100] "známe oddávna" [1978.1.1 1978.12.31] [0 100 100 0] "" [1979.1.1 2024.12.31] [0 0 0 0] "" endlookup
Many thanks Pavel
