Create Icon entity through the api

Hi @davidma

@davidma

Do you have a recommendation for how best to generate the acceptable <hex_encoded_16px_wide_jpg> from a png file?

There is nothing special for png file. This is the code I used.

img_b64 = base64.b64encode(open("16x16_jpg_png_file", "rb").read()).decode('utf-8')
