Hello On debian jessie Therion 5.3.14-1 (woops there is a new version, but I doubt it changes be below) For those who do not want to follow the whole long mail it can be summerised as - preview above/below fall of the page (bug?) - can we have colour preview-above/below map to have the same colour preview as the offset part - a possible bug when trying to offset all parts - although could be just my mis-use of the offset! Now the detail..... I have a cave (more of a bolder chock, really) that I have had the misfortune to survey. now when I come to try and present it I am having to think of novel ways that will make it useable, so have been looking at offsets and maps. This has lead to me finding bugs, or possibly it might be just pushing the use well beyond where it was intended to go. So I have used offsets and colour by maps successfully before, so have a basic understanding of what they do. All data available as usual at http://www.cave-registry.org.uk/svn/Burrington/Reads/ not all these tries have been committed, it is work in progress so joins and most of the detail have not been done.... So with the line in the thconfig file of select ReadsM@Reads -map-level 1 and colour map-fg map In the th file I have map ReadsM Level1M [0 -20 m] below Level2M [0 -40 m] below Level3M [0 -60 m] below Level4M [0 -80 m] below endmap Which does not work as expected, each of the 4 levels is coloured, but they are not in offset So I played and changed to thconfig line map-level setting select ReadsM@Reads -map-level 0 Offset works but they are not in colour (althugh it seems that the programmer had not expected all levels to be displaces, so the 'shadow' is now not on the page, which must be a bug) So I decided to get round the none colour 'bug' by doing the offset to inside the Level1M. I had edited it to map ReadsM Level1M Level2M [0 -40 m] below Level3M [0 -60 m] below Level4M [0 -80 m] below endmap map Level1M DryEntM@DryEnt [0 20 m] below MainChamberM@MainChamber [0 20 m] below JuncAlterRoute2M@JuncAlterRoute2 [0 20 m] below JuncAlterRouteM@JuncAlterRoute [0 20 m] below WaterM@Water [0 20 m] below WaterfallChamberM@WaterfallChamber [0 20 m] below endmap Which works fine, but a little tedious, unless there is a reason it would be easier if the whole map could be offset, rather than having to do every submap. Also the 'shadow' does not stay the same colour which is a shame as I need the colour to make it clear where the ofset came from. Which means this whole idea does not work, can I add this as a feature request, anyone got any bright ideas of how it can be done, best I have come up with is filling the colouring the maps and turning off all the other but that would be a manual merge, which I would prefer not to do I also tried map ReadsM Level1M Level1M_offset Level2M [0 -40 m] below Level3M [0 -60 m] below Level4M [0 -80 m] below endmap map Level1M DryEntM@DryEnt MainChamberM@MainChamber JuncAlterRoute2M@JuncAlterRoute2 JuncAlterRouteM@JuncAlterRoute WaterM@Water WaterfallChamberM@WaterfallChamber endmap map Level1M_offset DryEntM@DryEnt [0 20 m] above MainChamberM@MainChamber [0 20 m] below JuncAlterRoute2M@JuncAlterRoute2 [0 20 m] below JuncAlterRouteM@JuncAlterRoute [0 20 m] below WaterM@Water [0 20 m] below WaterfallChamberM@WaterfallChamber [0 20 m] below endmap Which I do not understand why but both Level1M_offset and level1M come out in the same colour, only slight problem is the detail is still on so the overview map is more complicated than is should be. There is the option of preview in the therion book and on the wiki page http://therion.speleo.sk/wiki/doku.php/tbe:wiki3?s[]=preview#outline it has preview There is also an option for the color of the background, “map-bg”. Other objects that can be coloured are “preview-above” and “preview-below” I have never understood this option so time to play map ReadsM Level3M Level4M preview above Level1M endmap with select ReadsM@@Reads -map-level 0 works but no colour and the same bug that the preview is not fully on the page. Making it select ReadsM@@Reads -map-level 1 Colours level 3 and 4 but no preview The therion book on page 31 has preview <above/below> <other map id> will put the outline of the other map in the specified preview position relative to the current map. Preview is displayed only if the map is in the map-level level as specified by the select command. Use the revise command if you want to add maps from higher levels to the preview. But I don't understand why it is not in the same level?? Is is possible to use the revise command to fix this.? thanks Andrew
