Im working on a project which requires 16 and 32bit grayscale tiff images. I can open the texture fine. I do my editing. However there is no way to save this data back out! When I select save as and type .tiff I gives a warning error "Reason: " but no reason is given. If i convert the data to RGBA it works, however I need to be able to save it back out as grayscale only! To reproduce: 1. open supplied tiff 2. save as > tiff (or save) Sample texture: https://drive.google.com/open?id=193SbCxR3I74o16TsiPdgSBqD3SdKGSSB
Created attachment 111473 [details] (Video) Hi. I can confirm (see video) in "Krita 4.1.0-pre-alpha (git 97015cd)" appimage - Ubuntu. - Cannot export grayscale 16, 32 bit float as TIFF. - No problem exporting grayscale 16 bit int as TIFF. It happens also in Krita 3.3.3 but the warning message is more informative, explaining that Krita cannot export grayscale to 16(32) bit float. Possibly related older report here: Bug 374958
Setting to wish, since this simply hasn't been implemented. Someone will have to digg into the tiff standard and the code to implement saving floating point channel grayscale images.
