[Therion] Lookup explo-date - avoiding overlying scraps

[Bruce Mutton]

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.

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
