Open lulalala opened 6 years ago

lulalala commented 6 years ago

Some images, while viewing on its own, has the correct orientation, but when it is displayed in html web page, the orientation is wrong.

@lulalala can you provide a sample image that causes this problem?

And I finally found an answer to this:

So basically all browsers will only respect EXIF orientation if it is displayed by itself (instead of inside an html file). This issue has been there since 2010.

So basically Mei has to process image so it is in the correct orientation without looking up to EXIF info.
