This is my code

from PIL import Image

ASCII_CHARS = ["@", "#", "$", " ", " ", "-", "|", ":", ".", " ", " ", " " ]

def resize_image(image, new_width=50):
    width, height = image.size
    ratio = height/width
    new_height = int(new_width * ratio)
    resized_image = image.resize((new_width, new_height))
    #resized_image.save('output.png')
    return(resized_image)

def grayify(image):
    grayscale_image = image.convert("L")
    #grayscale_image.save('output.png')
    return(grayscale_image)

# convert pixels to a string of ascii characters
def pixels_to_ascii(image):
    pixels = image.getdata()
    characters = ''.join([ASCII_CHARS[pixel//25] for pixel in pixels])
    return(characters)

def main(new_width=50):
    # attempt to open image from user-input
    #path = input("Enter a valid pathname to an image:\n")
    try:
        image = Image.open("picachu.jpg")
    except:
        print(path, " is not a valid pathname to an image.")
        return

    # convert image to ascii
    new_image_data = pixels_to_ascii(grayify(resize_image(image)))

    # format
    pixel_count = len(new_image_data)
    ascii_image = '\n'.join([new_image_data[index:(index+new_width)] for index in range(0, pixel_count, new_width)])


    with open("full_image.txt", "w") as f:
        f.write(ascii_image)

    fa = open("full_image.txt", "r")
    fb = open("trimmed_image.txt", "w")
    lines = fa.readlines()
    fa.close()
    lines = filter(lambda x: not x.isspace(), lines)
    fb.write("".join(lines))
    fb.close()

main()

and for picachu.jpg output is like this:

                             |-                   
                             $                    
                            |#$                   
                             ##.

       ..                     ..

So there is no problem with the code! But the thing is that i want to use Braille alphabet "⡿⡾⡹⡲⡱⠶⠷⠸" instead of "@#|- etc" and when i try :

ASCII_CHARS = ["\u280F", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " "]

it gives me this error UnicodeEncodeError: 'charmap' codec can't encode character '\u280f' in position 317: character maps to <undefined>

anyone have ideas how to solve this issue? you can find other Braille characters Unicode and Decimalcode here

  • Your terminal's encoding does not support braille characters, you need to configure it to support unicode.
