Pythonはランダム認証コードを生成する
28428 ワード
Pythonはランダム認証コードを生成し、PILモジュールを使用する必要がある.
1.画像を作成する
2.画像に任意の内容を描くためのブラシを作成します.
3.画点:
# 4.線:
# 5.円を描く:
# 6.テキストを書く:
# 7.特殊フォント文字:
#ピクチャ検証コード:
pip3 install pillow
1.画像を作成する
from PIL import Image
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
#
# img.show()
#
with open('code.png','wb') as f:
img.save(f,format='png')
2.画像に任意の内容を描くためのブラシを作成します.
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
3.画点:
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
# :
# :
draw.point([100, 100], fill="red")
draw.point([300, 300], fill=(255, 255, 255))
# 4.線:
img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
# :
# :
draw.line((100,100,100,300), fill='red')
draw.line((100,100,300,100), fill=(255, 255, 255))

img = Image.new(mode='RGB', size=(120, 30), color=(255, 255, 255))
draw = ImageDraw.Draw(img, mode='RGB')
# : ( )

draw = ImageDraw.Draw(img, mode='RGB')
