Using ART as a RAW decoder

As ART is a RawTherapee derivative, is it possible to use it as a RAW decoder for GIMP?

If so how? This is on a Windows 10 box.


On Linux it should be possible to create a wrapper script that will allow the gimp plugin to call art instead of RT, but I’m not sure if that will work on windows, because windows might search for RT in the registry. I guess someone would need to try… Sorry if this is not very informative

Hi Alberto,

Thanks for this feedback.

Hello, if I’m not mistaken, this mechanism doesn’t work anymore in Gimp (on Linux at least). It did work a year ago or something, with the early versions of the Gimp 2.10.x series.

Simple workaround: open your raw file in ART, then click the button Send to Gimp.

Great idea. Would you please be so kind as to help me find the “Send to Gimp” button?


First provide the GIMP install dir in preferences>general>external editor, and select GIMP as external editor


It will not work with blanks in image name.

Ok. That’s interesting about blanks in the image name as all my image names have blanks in them.

I had clicked that button and it churned for a moment or two and then nothing happened after it was done, That would explain why.

Seems like an odd artifact.



Good to know – I’ll take a look
