Python Image Resize

How it works

1. Upload image to the server.
2. Image is resized when it is stored on the server.

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 Python SDK uses the Python Wand-Py library transform method to resize images before storing them on disk. You can use all the options available for it.

Copy

options = {
    # Find more about resize parameter format on http://www.imagemagick.org/script/command-line-processing.php#geometry
    'resize': '300x300'
}

try:
    response = Image.upload(CustomAdapter(request), '/public/', options)
except Exception:
    response = {'error': str(sys.exc_info()[1])}
    
return json.dumps(response)

Complete Example

Copy

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

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