Regarding the map-image: As far as I know, Therion will not produce a JPG file. However ...
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. On Linux you need the ImageMagick package. Most distributions include it as a base item. With that you use the "convert" command: convert -density 300 -rotate 90 infile.pdf outfile.jpg -density sets the dots-per-inch in the output file. -rotate rotates the image 90 degrees before saving. Convert has hundreds of options Spend some time with the man page. There is a Windows version of ImageMagick. -- Bill Gee On Monday, December 2, 2019 2:12:57 PM CST Tarquin Wilton-Jones via Therion wrote: > Hi folks, > > When you colour a survey by depth (color map-fg altitude), it colours it > based on the scraps that have been selected.
