Cloudinary transformation

With cloudinary is possible to apply an image transformation uploading an image.

This feature transform images on the fly to any required format, style and dimension and optimizes images to have the minimal file size.

Open PhotosController and change the uploadParams of AddPhotoForUser.

While cropping a picture to a square aspect ratio the gravity parameter decides how to center the crop. With the parameter faces it detects all the faces in an image and uses the rectangle containing all face coordinates as the basis of the transformation (faces:center defaults to center gravity if no face is detected).

var uploadParams = new ImageUploadParams()
    File = new FileDescription(file.FileName, stream),
    Transformation = new Transformation()
