If a map export to pdf is attempted at too large a scale, we get the error;
Therion\therion.exe: error -- scrap scrap609@ defined at 1-BigEntrance.th2 [4135] is too large to process in metapost in this scale -- maximal scale for this scrap is 1 : 336 This I am familiar with, and know how to deal with. It is because the maximum 'size' of a pdf output can be 5m x 5m or thereabouts. If we try too small a scale, we get a similarly helpful error message. Therion\therion.exe: error -- thconfig.thc [20] -- thconfig.thc [20] -- scale out of range -- 1 5000000000 Again, the error message is explicit and helpful. If there is a scrap with no stations, then the error message is; Therion\therion.exe: error -- Map is too large for PDF format. Try smaller scale! To save the user searching for a scale that works it would be helpful to change this error message to "scrap has no point stations defined - cannot be scaled". Bruce
