[digikam] [Bug 429853] Aspect Ratio One Pixel Error

I cannot reproduce the problem with the local file export tool either. The
image size 3846x3077 is exported as 800x600 if an edge length of 800 is set.
Even a test with the BQM shows no problem.

Or are you talking about a plugin to upload to a web service?

As I said with the scaling tool in the editor, the result would be 800x600. We
may be able to round better in the local export tool. But the possibility of
800x639 or 800x641 coming out can always exist.

If I export the picture to local storage, I can choose the width of the image.
Set this to 800px and start export, then the image becomes 800x639.

I tested also the crop feature with the ratio 5:4, and the result given
corresponding to Maik results.

The results is also the same with Windows application as Paint.net or Xnview.

Darktable cuts 5:4 just like digiKam (3846x3077).

I can understand that you would like to see the usual page division factor of 4
for digital photos. But is that really the standard for cutting? A test with
Gimp shows the same result as digiKam.

The problem cannot be solved, there is always a 1 pixel error. Calculator
itself, the desired aspect ratio is 1.25.

Original image:
3878/3102 = 1.25016

digikam cut:
3846/3077 = 1.24991 deviation: 0.9

1st attempt:
3846/3076 = 1.25032 deviation: 0.00032

Second attempt:
3846/3078 = 1.24951 deviation: 0.00049

As you can see, the digiKam result has the smallest deviation from the average
of 5:4. By the way, if you scale the image with digiKam, the result is 800x600.
