example

from PIL import Image, ImageDraw, ImageFont

def drawText(bg, text: str, spacing: int, font, origin, color):
    img_clear = Image.new("RGBA", bg.size, (255, 255, 255, 0))

        draw.text((origin_x + sum(pads), origin_y), i, font=font, fill=color)
        pads.extend([font.getbbox(i)[2], spacing])

    return Image.alpha_composite(bg, img_clear)

for i in range(0, image.width, 100):
    image.paste((0, 0, 0), (i, 0, i+50, image.height))

normal draw

from PIL import Image, ImageDraw, ImageFont

image = Image.new("RGBA", (1024, 512), (100, 200, 255))
for i in range(0, image.width, 100):
    image.paste((0, 0, 0), (i, 0, i+50, image.height))

font = ImageFont.truetype("font.ttf", size=45)
draw = ImageDraw.Draw(image)
draw.text((100, 200), "Hello World", font=font, fill=(255, 255, 200))
draw.text((200, 400), "Good Morning", font=font, fill=(255, 100, 200, 150))
draw.text((800, 100), "Good Night", font=font, fill=(155, 100, 255, 40))
image.save("output_.png")
