| One of Therion's key features is that drawings are created in small pieces - scraps. A scrap is the smallest indivisible part of the drawing that can exported to create an output.\\ | One of Therion's key features is that drawings are created in small pieces - scraps.

| Most maps contain many scraps, and if they don't happen to appear perfectly joined by coincidence, then you should "join" these individual scraps to get Therion to morph them together. There are three ways to do it; fully automatically in *.th2 file, semi-automatically scrap by scrap, and manually line by line (if you must specify exactly which lines and points join).

| + | Note that this works using passages defined by lines of "wall" type (even if their "-outline" is set to "none"). It does not join other types of line. It normally expects to find pairs of lines, one on each side of the passage. If there are multiple passages that need to be joined between pairs of scraps, you can normally use the "-count" option to say how many possible passage joins Therion should search for. | ||

| + | The lines (just like maps, scraps, points and stations) are referenced by their ID directly inside their survey - inside a subsurvey, this would be as id@subsurvey (or id@subsurvey.subsurvey for nested subsurveys) - so make sure you have assigned an ID to each line that needs to be joined using the join command. | ||

| + | ====How to make map outputs match ISO paper size proportions==== | ||
| + | from Chris Hayes | ||
| + | |||
| + | ISO paper sizes have an edge length ratio, H:W, of √2:1, or vise versa. However when exporting maps to pdf, Therion makes the pdf exactly match the bounds of the cave, plus any images or legend elements that we might include with the layout. This does not typically match an ISO paper size, or the proportions thereof. | ||
| + | |||
| + | |||
| + | If we want our exported map output to scale nicely to print to a standard paper size (e.g. A4, A3, A1) then we need to cunningly include a map-header and or a map-image element to nudge the size of the pdf 'paper'. | ||
| + | |||
| + | |||
| + | * Compile a map with ''map-header 0 100 nw'' and ''map-header 100 0 se'' to get the dimensions, H and W of the pdf, then modify the map-header specification and compile again. | ||
| + | |||
| + | * For portrait outputs; add / remove ''delta H = 50*[√(2)*W/H -1]'' to the y positions | ||
| + | * For landscape outputs; add / remove ''delta W = 50*[√(2)*H/W -1]'' to the x positions | ||
| + | |||
| + | |||
| + | # Example for a portrait output, with modified y positions | ||
| + | map-header 0 109.79986718266315 nw #place map header in top left corner | ||
| + | map-image 100 -9.79986718266315 se Club_Logo.png #place an image such as club logo in bottom right corner | ||
| + | |||
| + | The output will probably not match an ISO paper size that you have in your printer, but it will be of the correct proportion to be scaled to fit thatISO paper size. | ||
