The width and height of my image are reversed about imagesharp

if you run the img.Mutate(x=>x.AutoOrient()) it'll fix up the pixel data to be orientated as expected.

Note this is a difference stemming from audience expectations between image viewing and programmatic image manipulation. Image viewers are processing the data for humans to understand and physically look at where as ImageSharp is for manipulating the individual pixel data. Rotating the pixel data in memory (rather that adding a tag to tell a viewer to do it for you, which is the case here) would increase memory usage and loading time in places where not everyone will want/need that behaviour.

The width and height will be accurate. The EXIF metadata will indicate that the image is rotated.

For what it's worth, this has been discussed before. @JimBobSquarePants has an example of a quick program you can write to verify what they're saying, in #1613

So ImageSharp will not help to reverse width and height?
Since I see most of image viewer software like PS, window10 photos can handle it well...
