ImageDraw.Draw(image)ImageDraw类给我们提供了丰富的选择，支持我们绘制圆弧，饼图，折线图，矩形图，多边形等方法，下面我们来一一介绍:绘制线形图我们可以绘制直线和折线图，代码如下：draw.line...((50, 50, 100, 150), fill='green', width=6)draw.line((50, 200, 75, 300, 100, 250, 75, 200), fill='red

width), random.randint(0, height)) end = (random.randint(0, width), random.randint(0, height)) draw.line...width), random.randint(0, height)) end = (random.randint(0, width), random.randint(0, height)) draw.line
