Hi folks, When you colour a survey by depth (color map-fg altitude), it colours it based on the scraps that have been selected. This is normally useful. When you produce an output with only one part of the survey (eg. a zoomed-in section of a more complex part of the survey), however, it would be more useful to be able to keep it the same colour as it was in the larger survey, so that a viewer can quickly see which part of the cave they are looking at, and see that the colours match. (My own use-case is different, but the solution would be the same.) Is there, for example, a way to say this: layout local color map-fg altitude endlayout source "cave.th" select subsectionMP@subsection.cave altitude-relative caveMP@cave export map -proj plan -layout plan -o "cave.pdf" Alternatively, is there a way to add scraps belonging to the highest points and lowest points into the map, but not have them render, while still being used for altitude colouring (this seems like a hack rather than being a dedicated solution). Alternatively (and I know this will seem a little out of place here, but it is an alternative solution for what I need), is there a way to import a map-image, and crop it to only include a portion of the image?
