Is there some reason the aspect ratio can't be specified with two input boxes: x : y ?
Then the person could imput 16 : 9 or 1.7777 : 1 or 8 : 4.5 -- however they preferred. [ And if they wanted it rotated, then 9 : 16 .] Personally, I'd prefer the flexibility over the convenience. --alan * August Schwerdfeger (aug...@schwerdfeger.name) [181116 14:22]: * Subject: Re: [darktable-dev] Feature request (Cropping module GUI): > The problem with selecting these integers based on commonly-used aspect > ratios, is that the only real use for this feature would be in "freehand" > mode when cropping to an *unusual* aspect ratio; the common ones like 16:9 > are represented in the "aspect" combo box and it is much easier to select > the "16:9, HDTV" option to constrain the ratio. > > -- > August Schwerdfeger > aug...@schwerdfeger.name > > On Fri, Nov 16, 2018 at 2:51 PM Jan Ingwer Baer <jib...@web.de> wrote: > > > On 16-Nov-18 18:26, Heiko Bauke wrote: > > > Hi, > > > > > > Am Freitag, 16.
