brucemutton XTherion - Finding drawing where extents are large
Line 48: Line 48:
   * Always check the small yellow tick on first point of line object. It shows the FREE space side of line. It means you should draw walls in counterclockwise direction, the blocks in clockwise direction, pit or chimney in counterclockwise direction, etc. If you made a mistake there is "​reverse"​ option in "Line commands"​ section.   * Always check the small yellow tick on first point of line object.

 +===Finding Objects if you have large blank extents===
 +If you have inserted an xvi or drawing image with large extents, it may be difficult to find the drawing objects by panning or zooming around the drawing interface.\\
 +An easier way to locate any drawing objects is to open the Objects window on the top right-hand side of the XTherion interface, and click on one of the objects listed.
 +Except for scraps, and areas, most objects will be selected and the drawing area will be panned to show the object mid-screen.\\
 +
 +
 +
 +If you are repeatedly creating th2 files with large blank extents around the drawings and images, then it may be because of spurious drawing lines made accidentally when navigating during data collection with PocketTopo, TopoDroid, SexyTopo or the likes. ​ It may also be because of inappropriate parameters used to export data from these applications to Therion.

 +====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.
