[Qgis-user] Symbolizing a discrete or a boolean raster (Stéphane Henriod)

Hi all

upon advice from Andreas, I started a formal description of the
requirements for such a feature:

https://docs.google.com/document/d/1cDemM2m88_mbs65sYzfBbVdHI_ObOjf_i35ne3OKsRs/edit?usp=sharing

Please, anyone interested, do check, comment, add, correct,... Once we have
a "final" version, I will inquire a more precise financial estimation. Then
let's see how we can move forward!

Thanks and cheers

Stéphane
