BMP import/export

[lanrat]

Describe the feature you'd like
It would be great if the badge magic app could export and import bmp images

Additional context
The OEM app has this feature.

Let me look what changes are required to read this binary

I wrote that Python script to convert images to json that can be imported with the mobile app:

from PIL import Image
import json

def bmp_to_hex_list(image_path):
    image = Image.open(image_path).convert('1')
    image_width, image_height = image.size
    char_width = 8
    char_height = 11
    num_chars = image_width // char_width
    hex_data = []
    for col in range(num_chars):
        binary_str = ""
        for y in range(char_height):
            for x in range(char_width):
                bit = 1 if image.getpixel((col * char_width + x, y)) == 0 else 0
                binary_str += str(bit)
        hex_str = hex(int(binary_str, 2))[2:].zfill((char_width * char_height) // 4)
        hex_data.append(hex_str)
    return hex_data

badge={'messages':[{'text':bmp_to_hex_list('badge.bmp'),'flash':False,'marquee':False,'speed':'0x60','mode':'0x00','invert':False}]}

print(json.dumps(badge, indent=4))

@benjaminbellamy thats wonderful. Would you like to add an import feature that can do the same in the app? Feel free to create a PR
