Question

Python

Answer 1

from PIL import Image, ImageDraw


def round_corner(radius, fill):
    """Draw a round corner"""
    corner = Image.new('RGBA', (radius, radius), (0, 0, 0, 0))
    draw = ImageDraw.Draw(corner)
    draw.pieslice((0, 0, radius * 2, radius * 2), 180, 270, fill=fill)
    return corner


def procent_line(size, radius, fill1, fill2, p):
    """Draw a rounded rectangle"""
    width, height = size
    rectangle = Image.new('RGBA', size, fill2)
    corner_b = round_corner(radius, fill2)
    corner_f = round_corner(radius, fill1)
    rectangle.paste(corner_f, (0, 0))
    rectangle.paste(corner_f.rotate(90), (0, height - radius))  # Rotate the corner and paste it
    rectangle.paste(corner_b.rotate(180), (width - radius, height - radius))
    rectangle.paste(corner_b.rotate(270), (width - radius, 0))
    rectangle.paste(corner_f.rotate(180), (int(width*p - radius), height - radius),corner_f.rotate(180))
    rectangle.paste(corner_f.rotate(270), (int(width*p - radius), 0),corner_f.rotate(270))
    ImageDraw.Draw(rectangle).rectangle([radius,0,int(width*p - radius),height],fill=fill1)
    return rectangle


img = procent_line((400, 40), 20, "yellow", "gray", .25)

img.show()
