In English

Piximetre is working in two languages: French and English.
By default, the language is automatically selected according to Windows.
You can change the language in Parameters, Advanced...

Unfortunately, the tutorial is only available in French. Sorry !

However, some English-speaking users, such as BORIS ASSYOV on its website 'boletales.com',  carried out a presentation in English that may help you to take control of the software. It concerns an earlier version but the main is. Thank you to Boris: see here.

The Piximetre's author is not enough fluent in English language to translate this tutorial. He asks for goodwill people to help him to translate one or more pages (free, of course, because the software is free - but with mention of the name accordingly).
