Encoding images in Base64
-
I need to encode images in base64 for the purposes of passing them through an x-callback-url. I have this code but it's not working:
#coding: utf-8 import workflow import clipboard import photos import base64 source_selection = workflow.get_variable('source') if source_selection == 'photo': image_selection = photos.pick_image() else: image_selection = clipboard.get_image() if not image_selection: console.alert('No Image', 'Clipboard does not contain an image') w, h = image_selection.size encoded = base64.b64encode(str(image_selection) workflow.set_variable('encodedImage', str(encoded)) workflow.set_variable('origSize', str(w))
Any ideas?

One issue that might be happening is that when its encoded to an callback URL, it's including characters that aren't URL safe. Try using
base64.urlsafe_b64encode(str(encoded))
.
