Describe the bug I input a image that resolution is 4024*6048, as you can see that is a vertical image.

Whatever "resize to fit" option I use, the output image is always in horizontal resolution like 6048*4024.

Does the issue occur if you check the "Keep metadata" checkbox in the compression options?

When compressing to webp is selected, the image is still incorrectly rotated. Images are not rotated unexpectedly when trying to compress to jpg or png.

@Csrayz The original image is WebP or any other format?

Csrayz commented 8 months ago

@Csrayz原图是WebP还是其他格式？

The original image is a jpg, and when I tested it, I found that only certain images produced these kinds of strange phenomena. The operation recording and source files are attached below.

This should not happen when the output format is the same as the original file, but can occur if, for example, the original is JPG and the output is WebP. It's related to #196 because Caesium cannot keep the metadata of the original file if is compressing to another format. I'm working on a solution for this.
