问题
I am facing a problem using Dropzone with an image: Dropzone is sending a file to my server that is different from the original file.
I am using the library from the CDN https://cdnjs.cloudflare.com/ajax/libs/dropzone/5.7.0/dropzone.min.js.
The file I send is https://picciao.com/img/photo-1.jpg The file I receive on my server is https://picciao.com/img/products/k1fDK7MRp40c3TVwPOu4FZOO.jpg
As you can see, the image hasn't the same orientation.
I do not understand where Dropzone is modifying my file.
As the problem seems related to image orientation / EXIF data, I tried to include the exif.js library but that did not solve the issue.
Do you have an idea please?
回答1:
Make sure you're not using the resizeWidth or resizeHeight options. I'm using 5.7.1 and there seems to be a bug with it not correctly resizing portrait images. The orientation get messed up.

Either use resizeWidth or resizeHeight NOT both options and image will resize with proper aspect ratio.
