Hmmm... OK, one more WILD idea: Print the colored map as an atlas. There are a lot of parameters that go into generating an atlas. I suspect with some playing around you could get somewhat close to getting the portion of the cave you want on one page of the atlas.
From there it is a simple matter to extract one page from a PDF file and make it into a new file.
I was not anticipating that anyone but you would need ImageMagick. I thought the use case was that you would generate and distribute the image files, and everyone else would simply admire your handiwork! :-) -- Bill Gee On Monday, December 2, 2019 3:08:41 PM CST Tarquin Wilton-Jones via Therion wrote:
It is quite easy to turn a PDF into a JPG, especially on Linux. Once that is done, then any decent photo editor can crop it. The legend will be a problem. I suppose you could crop out two sections (the legend and the cave portion you want) and paste them into a single image.
Thanks for the suggestion.
For me, this is all very easy indeed, and if it were only me that mattered, I would probably go down this route (as I have done with wkhtmltopdf to get a modified cavelist into a survey). Even removing the legend part is very easy with the various Therion options. But my intention is to be able to share my surveys, source and all (they are going to be one of the open source licences). Sadly, I cannot expect another user to have to install and configure ImageMagick, and make adjustments when adding new cave passage to a survey which shifts the positions of things.
This is why I am hoping for a solution that works entirely within Therion, if at all possible.
Still hoping for "altitude-relative caveMP@cave", which would be so much easier for both my use case, and the use cases that I can see others wanting :) _______________________________________________ Therion mailing list Therion@speleo.sk https://mailman.speleo.sk/listinfo/therion
