Image Upload

The Server Upload section describes the steps to upload an image to a server. Resizing images on the editor only changes the size displayed in the browser. Changing the physical size of an image occurs on the server side.

Resize Image

The editor's Ruby SDK uses the Ruby MiniMagick::Image method to resize images before storing them on disk. You can use all the options available for it.

Copy

class UploadController < ActionController::Base

  ...

  def upload_image
    options: {
      resize: {
        height: 200,
        width: 600
      }
    }

    FroalaEditorSDK::Image.upload(params, "public/uploads/images/", options)
  end

  ...

end

Complete Example

Copy

<script>
  new FroalaEditor('.selector', {
    // Set the image upload URL.
    imageUploadURL: '/image_upload',

    imageUploadParams: {
      id: 'my_editor'
    }
  })
</script>

Copy

class UploadController < ActionController::Base

  ...

  def image_upload
    options: {
      resize: {
        height: 200,
        width: 600
      }
    }
    render :json => FroalaEditorSDK::Image.upload(params, "public/uploads/images/", options)
  end

  ...

end
