Python 生成字母验证码图片

# 240 x 60:

image = Image.new('RGB', (width, height), (255, 255, 255))

# 创建Font对象:
font = ImageFont.truetype(font_path, 36)
# 创建Draw对象:
draw = ImageDraw.Draw(image)

# 填充每个像素:
for x in range(width):
    for y in range(height):
        draw.point((x, y), fill=rndColor())
        
# 输出文字:
letters=rndCharList()

for t in range(4):
    draw.text((60 * t + 10, 10), letters[t], font=font, fill=rndColor2())
#for t in range(4):
#    draw.text((60 * t + 10, 10), rndChar(), font=font, fill=rndColor2())

# 模糊:
image = image.filter(ImageFilter.BLUR)
image.save('code.jpg', 'jpeg');

plt.imshow(np.array(image))
plt.show()
