Subject: RAW processing plug-in - any interest?<br class="">

Dear Krita experts,<br class="">
<br class="">
this is my first post here, so let me introduce myself: I am the developer of an Open Source RAW and raster image processing program called PhotoFlow (<a href="https://github.com/aferrero2707/PhotoFlow" rel="noreferrer" target="_blank" class="">https://github.com/<wbr class="">aferrero2707/PhotoFlow</a> <<a href="https://github.com/aferrero2707/PhotoFlow" rel="noreferrer" target="_blank" class="">https://github.com/<wbr class="">aferrero2707/PhotoFlow</a>>).<br class="">
It can develop RAW images with a quality and flexibility comparable with other Open Source tools like RawTherapee and Darktable.<br class="">
However PhotoFlow, unlike other RAW processing tools, is based on non-destructive adjustment layers.<br class="">
<br class="">
Recently I have been developing a plug-in for the GIMP editor. The plug-in allows GIMP to open RAW images by delegating the RAW processing to the PhotoFlow executable.<br class="">
It also allows to use PhotoFlow as a filter plug-in, for non-destructive editing of the image data from existing GIMP layers.<br class="">
<br class="">
PhotoFlow, as well as the GIMP plug-in, are available for Linux, OSX and Windows.<br class="">
The current plug-in code can be found here: <a href="https://github.com/aferrero2707/PhFGimp" rel="noreferrer" target="_blank" class="">https://github.com/<wbr class="">aferrero2707/PhFGimp</a><br class="">
<br class="">
<br class="">
Would there be any interest for a similar functionality in Krita? If yes, I’m ready to collaborate in porting the plug-in code to Krita, although I will surely need lots of assistance as I am not familiar at all with the Krita framework…<br class="">
<br class="">
<br class="">
With my best regards.<br class="">
