Yes, but it was very low on the TODO list until now. But you are not  
the only one who is interested in it, so may be it is time to try  
something.

Well, I see solutions possible.

1. Create "File->Import" function in therion map editor, that will  
import vector drawing into map editor lines, points and area objects.  
I can imagine importing any text file (SVG or DXF). The only problem  
is, how to effectively organize this mess of lines and points after  
import. At least, there can be some simple import filter, that will  
assign correct line types/subtypes/options according to symbol XML  
tags in SVG or LAYER or other properties in DXF. But there will be  
definitely also needed some interface to manage multiple objects at  
one time in xtherion (multi selection or something like that).

2. Support importing of SVG or DXF directly into therion data  
structure using import command (with some filter, that will again  
assign correct options to therion objects). This solution will never  
produce perfect results, but may help...

3. Support for bitmaps in scraps. OK - it is not a vector graphics,  
but it will allow you to receive a complete map very fast, even your  
existing maps are in the "paper-only" form. And this is already more  
or less possible using scrap -sketch option.

Well, I think we will soon (within a month) start working on #1 and  
#3. I am not sure about #2. Do you have some concrete project, where  
you would like to start? Do you have some concrete SVG files you would  
like to convert to therion? Or does anybody have another idea, how to  
solve this problem?

Regards, S.
