用PIL Python实现双色线性渐变定位

from PIL import Image, ImageDraw

def linear_gradient(start_color, end_color, width, height):
    image = Image.new('RGB', (width, height))
    draw = ImageDraw.Draw(image)

    for y in range(height):
        r = int(start_color[0] + (end_color[0] - start_color[0]) * y / height)
        g = int(start_color[1] + (end_color[1] - start_color[1]) * y / height)
        b = int(start_color[2] + (end_color[2] - start_color[2]) * y / height)
        draw.line((0, y, width, y), fill=(r, g, b))

    return image

start_color = (255, 0, 0)  # 起始颜色为红色
end_color = (0, 0, 255)    # 结束颜色为蓝色
width = 500                # 图像宽度
height = 200               # 图像高度

gradient_image = linear_gradient(start_color, end_color, width, height)
gradient_image.show()
