A while back I asked

I have had "sketches on" (no quote marks) in my layout since my first (almost) Therion steps last year, and not      once have I had my jpg sketches exported to pdf.  I expect they       should, and I recall that the samples provided seem to do so -  I could find no difference between my code and the samples.

Stacho replied

Do you have -sketch option specified in your scrap? It does not work automatically.

In the scrap toolbar - last list box is background sketches. You need to click insert button below and then click on the appropriate picture. Then this picture should be listed in the "background sketches" listbox. Background images in xtherion are not seen by therion, you need to enable this manually.

And I replied with what I now realize is nonsense so I won’t repeat it.

And now I’ve given this some more time I still have the problem that sketches are not exported, but I have some insight as to why.

.

Stacho’s response above is consistent with the Therion book pg 20 and 32 explanations, and on studying the morphing sample code that comes with the installation, I think that I have been, and still are, following the instructions for the required actions within the map editor perfectly. (and I can see and trace my sketches as expected)

However on studying the text files produced by my map editor efforts, and those in the morphing sample I see that the –sketch option is missing from my *.th2 files.

From the Therion book…

sketch <filename> <x> <y> . underlying sketch bitmap specification (lower left corner coordinates).

So in theory I could manually add this option using the text editor, but there is a difficulty calculating the x, y co-ordinates.  I suppose it could be done by hand or by trial and error, but very time consuming.

Am I missing something, or is there something my map editor is not translating correctly?
