0.97.1: Sub-sampling info for 4:4:0 JPEG is wrong

Post by fireattack »

XnView: MP 0.97.1 64-bit
OS: Windows 7 64-bit

Test image: https://www.dropbox.com/s/el5k26hlal49v ... G.jpg?dl=1

In the info panel, it shows 1x1, 1x1, 1x1 (4:4:4) for a 4:4:0 jpeg:

It should show 1x2, 1x1, 1x1.

4:2:2 (2x1, 1x1,1x1) or 4:2:0 (2x2, 1x1, 1x1) display as expected.
