doug> I have a topic idea and/OR question-for-list-here+now, but only half a clue;
I seek the Grail (our group's collective mind meld) on....
Resizing/cropping images efficiently w/r/t
( a) my time to perform the file manipuation, and
(b) efficient+good JPG compression/filesize-shrinking.
In my nearly-abandoned Windows-OS world, I had/have an obscure tool ACDSee
which I paid $10-20 for, 25 yrs ago ! (still avail for windows only) which....
--- is very easy/quick to use in my opinion
--- does an easy image rotation if needed
--- does an easy crop-and-save (the main feature for me)
--- magically, without asking about quality/compression? DOES COMPRESS Very Well:
.... I can crop most images (eg typical smartphone jpg around 4mb for example,
........ I can crop most of it and save with a typical result = 10-20% of original file size = 400-800k
........... and you wouldn't believe how good the 10%-smaller image tends to look.
GIMP can do these, except seems to lack the magical quality of ACDSee for a downsize.
while doing GIMP's Crop first, then Export to JPG, GIMP Export asks for a QUALITY in the 1-100% range,
if I choose 10% I do get a 400k file, but it's grainy as you might expect,
and I wonder how ACDSee does such superior compression with barely any loss/grainy result. -------doug
