+ | ===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.\\ | ||
+ | For example, clicking on object 4 below, selects it and brigs it to the centre of the drawing area. | ||

+ | |||
+ | 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. | ||
+ | If drawings and export\imports are well posed, then your drawing area extents should not be much larger than your actual drawing.\\ | ||
+ | You can manually or automatically tweak the drawing area that is viewable for a particular file if you scroll down to the Drawing Area window near the bottom of the right-hand side of XTherion, and make adjustments there. | ||

+ | ====Showing centreline for parts of a cave, and passage walls for others==== | ||
+ | |||
+ | Sometimes you might have full survey data and drawings for some parts of a cave, while other parts might have only centreline data. It is possible to combine these in the same PDF output, using a map consisting of other maps, and other surveys: | ||
+ | |||
+ | map allcave | ||
+ | subsection_map@subsection #the part with walls drawn | ||
+ | othersubsection_survey | ||
+ | endmap | ||
+ | |||
+ | Note that you now cannot use " | ||
+ | |||
+ | ====Making a subset of the cave take its altitude colours from a larger part of the cave==== | ||
+ | |||
+ | When rendering a map (map-endmap), | ||
+ | |||
+ | When you want to render a subset of that cave, such as a map showing only the entrance series of a cave, you might want to have the colours match the colours that were used in the overall map, so that the parts of the cave are recognisable. One way is to use an [[examples# | ||
+ | |||
+ | Another approach, which allows Therion to continue using automatic altitude colours, is to [[#Showing centreline for parts of a cave, and passage walls for others|include the highest and lowest surveys/ | ||
+ | |||
+ | map foo | ||
+ | subsection_map@subsection #the part you actually want to render | ||
+ | othersubsection_survey | ||
+ | anothersubsection_survey | ||
+ | endmap | ||
+ | |||
+ | Your layout would then include this: | ||
+ | |||
+ | color map-fg altitude | ||
+ | symbol-hide group centreline | ||
+ | |||
+ | By hiding the centreline, you cause the unwanted surveys not to render at all, so the output acts like they were never included (it is cropped accordingly to show only the rendered part). | ||
+ | |||
+ | If you need to include a centreline-only section of the cave in your rendering, then the same approach works, but it is a little more convoluted. Create a scrap in the highest and lowest parts of the cave. Those scraps should contain only a single station point. It doesn' | ||

+ | ====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. | ||
+ | |||
+ | |||
+ | 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 ' | ||
+ | |||
+ | |||
+ | * Compile a map with '' | ||
+ | |||
+ | * For portrait outputs; | ||
+ | * For landscape outputs; add / remove '' | ||
+ | |||
+ | |||
+ | # Example for a portrait output, with modified y positions | ||
+ | map-header 0 109.79986718266315 nw # | ||
+ | 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. | ||
