[Therion] map-bg transparent

2012-09-12 Thread Bruce 
It is a long time since I made use of transparent map backgrounds, and on
trying just now I think it is no longer working (at least in 5.3.10, 5.3.9
and maybe earlier versions I get white backgrounds instead).

Or perhaps I am making a silly mistake?



I thought the problem might be the same as the bug in 5.3.5 when this
feature was first introduced 

http://article.gmane.org/gmane.comp.gis.therion/2349/match=map+bg+transparen
t

but it seems I get opaque white backgrounds with either syntax.



within an explicitly defined layout;



layout LayoutMapBulmer_System 

  colour map-bg transparent

endlayout LayoutMapBulmer_System 





or as part of the export map command;



export map   -projection [elevation 270 deg] \

  -layout LayoutMapBulmer_System \

  -layout LayoutMapBulmer_SystemElev   \ 

  -layout-colour map-bg transparent   \

  -output ./Output/MapBeautBulmerLate08System_Elev.pdf



You can test this by creating a pdf map with a transparent background and
inserting it into another map with 'map-image'.  



Does anyone else find that transparent backgrounds are not working?

OK, it can be done this way.

Thanks Martin
I think that sometimes a white opaque background would be desirable.
How about;

map-bg [100 100 100] #or
map-bg [100] #gives an opaque white background, and
map-bg off   #gives a transparent  background?

ie similar in concept to   map-header-bg off

If this is more complicated to code then your suggestion would be a good
interim solution.

It will be supported in the next snapshot (if map-bg is white or
omitted in layout).

[Therion] map-bg transparent

2010-06-15 Thread Bruce 
On the topic of maps within maps.



Therion inserts images with transparent backgrounds into maps correctly - at
least it has worked for me.

Is it possible to get therion to create a map with a transparent background?



Something like 'map-bg off' perhaps?



This would be useful sometimes when inserting map enlargements within a main
map output.
