GIMP - how to export image to base64

That was somewhat extremely surprising to me that GIMP does not provide Base64 exporter out of the box (but I am not the GIMP expert - maybe there is ;)). Nonetheless, as it seems to me a quite straightforward to implement such feature, I faced the challenge. After short googling and refreshing deep buried Python knowledge, it became simple, amazingly simple in fact. Here you are some details in three simple steps: 0. Open "Python Console" (don't be afraid, it does not bite you, or choke either ;)

Go to "Filters" menu -> "Python-Fu". The python console should appear.

1. Take an image

img = gimp.image_list()[0]  // assuming you'd got just one image opened

2. Read all bytes

bytes = open(img.filename, "rb").read()

3. Encode bytes with 'base64' algorithm

bytes.encode('base64')

Done.

And for "one-liner" fanboys, we can compact it into one line:

open(gimp.image_list()[0].filename, "rb").read().encode('base64')

bytes.encode('base64') puts some new-line characters, alternatively you can use the following:

import base64
base64.b64encode(open(gimp.image_list()[0].filename, "rb").read())
