[Therion] Therion Digest, Vol 221, Issue 2

Thanks Bill.

Marco has clarified that "point:photo" in Topodroid is not complete. So,
essentially, I shouldn't be using it. Event if it were complete, Therion is
not programmed to handle it. As you suggest, in Therion it is simply placing
a symbol, in this case a symbol that looks like a camera. 

After what you say about placing photos being a pain, I'm now leaning toward
putting the camera symbol on the map with a reference number associated with
it and providing the images in separate lookup table somewhere. That
probably serves my purpose just as well.

Cheers

Nigel

Hi Martin,

The map-image command doesn't work for me for some reason. I'll persevere
with it to get it going eventually. 

What I'd like to do is automatically process the photo point type directly
to insert the image at the point on the map without having to manually
insert the photo image. As part of the solution I'm also hoping to stop
Therion erroring when it sees the photo point type that Topodroid has
inserted into the file. 

Cheers

Nigel

Hi,

I have a sketch export from Topodroid into Therion format that contains a
Photo point. In Topodroid the point is associated with a photograph in .jpg
format. The export .th2 file shows a line like this :

point 258.69 97.28 photo -text "a photo" -photo 1.jpg

I'm trying to get a photo image to appear on the map at that point. Therion
doesn't like the -text or the -photo parameters. The Therion book doesn't
say a lot about it and doesn't include those parameters or any others
relating specifically to the photo point type. Is there any way to use the
point data from Topodroid to actually place the image on the map. It looks
like it can't be done natively so maybe some Metapost code that will
interpret the data and write the image? I don't know Metapost well enough to
know if it can be done. 

Any suggestions would be greatly appreciated.

Thanks

Nigel

As Nigel is experiencing, adding photos to a map is a real pain.  It is
right up there with adding profiles, mainly because the same basic method is
used.

What I found is that photos and profiles have to be the VERY last things you
put on a map.  Otherwise - If the map changes at all, especially the size,
then the placement of the photos and profiles is changed too.  You cannot
ever count on them remaining in the same place relative to the rest of the
map - and relative to the legend.

I think the current "point:photo" object is only to indicate that a photo
was taken.  As far as I can tell, it has no function for actually placing a
photo.  It would be nice to have more details in the Therion Book.

On most of my maps I treat profiles like cross-sections.  In a sense they
are cross-sections viewed orthogonally to regular cross-sections.

I also never use photos.  It is just too much work to try and figure out how
to place them.
