Hi, the problem with images should be fixed now. Best wishes Martin On Wed, Sep 2, 2026 at 10:41 AM <bruce@tomo.co.nz> wrote:
Thanks martin, that makes sense.
I thought I had a recent snapshot, but not recent enough.
I installed Therion 67248d35 and set it up for Luatex. It compiled a small test project, but fails to render the png background sketches and reports this warning.
*C:\Program Files\Therion\therion.exe: warning -- unable to read D:/CaveSurvey/th_Canaan/150Tomo/./ptopo/1- 50TomoPlanSketch-300-02of02-transparent.png -- Magick: NoDecodeDelegateForThisImageFormat `D:/CaveSurvey/th_Canaan/150Tomo/./ptopo/1-50TomoPlanSketch-300-02of02-transparent.png' @ error/constitute.c/ReadImage/739*
Reverting my therion.ini and application back to Therion d6d9a18f all is well again.
So for now I will pause my luatex adventure until the recent round of Therion edits settles down. Since the string “decode” turns up in my error and features in recent commits, I expect they are the culprit.
Should I create an issue on github, or will this message be sufficient to prompt another look at decode?

Oh, I meant a recent snapshot of Therion, sorry for the confusion. LuaTeX is now included in the windows installer.

I’ll need some more hand holding.
I can find https://github.com/lualatex which gives many variations that I cannot make sense of, and https://gitlab.lisn.upsaclay.fr/texlive/luatex which looks like it has a definitive install, but it is not github.
Is it one of these?

Hi Bruce,
you need
- a recent development snapshot from github
- to specify the full path to luatex.exe, like pdftex-path "C:/Program files/Therion/bin/windows/luatex.exe"

From my query two weeks ago, and Martin’s suggestion I try LuaTeX…
I’ve edited *C:\Program Files\Therion\therion.ini* to include… pdftex-path "luatex"
I’m missing something:
Running my thconfig with Mapiah, I get a log file that ends with…
*making map ... done*
*'luatex' is not recognized as an internal or external command, operable program or batch file.*
*C:\Program Files\Therion\therion.exe: error --Press ENTER to exit! pdftex exit code – 1*
Running my thconfig with XTherion, there is no mention of Luatex. I get a log file that ends with…
*##################### end of pdftex log file #####################*
*C:\Program Files\Therion\therion.exe: error -- pdftex exit code -- 1*
*writing xtherion file ... done*
I checked my %APPDATA%\ folders, and the only Therion related ini in there is Loch.ini
Any ideas?
Bruce
