Hi, in master branch, using Colors > Desaturate (luminosity) and Image > Mode > Grayscale on a RGB image (whatever the image precision) gives different results. This does not appear in branch gimp-2-8, since the 2 actions are computed the same way (using GIMP_RGB_LUMINANCE). In master, for Desaturate (luminosity) filter, GIMP_RGB_LUMINANCE is used on a R'G'B'A buffer. For Grayscale conversion, drawables' buffers formats are converted to babl_format Y (or Y' according to the initial format). As these 2 actions seem to have the same goal (obtain the relative luminance), shouldn't we obtain the same result ?
