I am trying to add COLOR emojis onto images as overlay, but it seems like the emojis keep being rendered in black and white, and also transparent:

example output

This is what I’m currently working with:

def add_text_overlay(image_path, text, font_path, emoji_font_path, font_size, text_spacing, x_padding, output_path,
text_position, offset_x, offset_y):
with PILImage.open(image_path) as img:
img = crop_and_resize(img, 1080, 1440)

    draw = ImageDraw.Draw(img)
    font = ImageFont.truetype(font_path, font_size)

    # Load the emoji font using PIL
    emoji_font = None
    try:
        emoji_font = ImageFont.truetype(emoji_font_path, 137)  # Adjust pixel size as needed
    except OSError as e:
        logging.error(f"Unable to load the emoji font: {e}")
        logging.error(f"Path checked: {os.path.abspath(emoji_font_path)}")
        emoji_font = font  # Fallback to regular font if emoji font fails

    lines = wrap_text(text, 28)
    fixed_line_height = font_size + text_spacing
    total_text_height = fixed_line_height * len(lines)

    initial_text_y = (img.height - total_text_height) / 2 + offset_y

    for i, line in enumerate(lines):
        text_bbox = draw.textbbox((0, 0), line, font=font)
        text_width = text_bbox[2] - text_bbox[0]

        if text_position == 'left':
            text_x = x_padding + offset_x
        elif text_position == 'right':
            text_x = img.width - text_width - x_padding + offset_x
        else:
            text_x = (img.width - text_width) / 2 + offset_x

        text_y = initial_text_y + i * fixed_line_height
        if text_x < 0:
            text_x = 0
        if text_x + text_width > img.width:
            text_x = img.width - text_width

        # Draw each character with the appropriate font
        for char in line:
            char_font = emoji_font if is_emoji(char) else font  # Use emoji font for emoji characters
            draw.text((text_x, text_y), char, font=char_font, fill="black")
            text_x += char_font.getbbox(char)[2]  # Update this line to use getbbox

    img.save(output_path)

I was having “invalid pixel size” error for a while until I changed the pixel size to 137. then afterwards it just drew the monochrome transparent emoji.
