Python画图

因为工作中需要用到一些特殊的图卡，使用windows自带的画图工具不好实现，将python生成图卡的学习记录保留在这里。

本文主要是根据提供的像素RGB值来生成指定图卡，方便左右屏幕单独显示。

import random

from PIL import Image, ImageDraw, ImageFilter

def rndColor():
    return (random.randint(128, 255), random.randint(128, 255), random.randint(128, 255))

def leftColor():
    return (220, 220, 220)

def rightColor():
    return (170, 170, 170)

def singleColor():
    image = Image.new('RGB', (3648,1920), (255, 255, 255))
    draw = ImageDraw.Draw(image)
    for x in range(24, 1823):
        for y in range(1920):
            draw.point((x, y), fill=leftColor())
    for x in range(1847, 3647):
        for y in range(1920):
            draw.point((x, y), fill=rightColor())
    image.save('singleColor.png','png')

def mixRowColor():
    image = Image.new('RGB', (3648,1920), (255, 255, 255))
    draw = ImageDraw.Draw(image)
    for x in range(24, 1823, 2):
        for y in range(1920):
            draw.point((x, y), fill=leftColor())
            draw.point((x+1, y), fill=rightColor())
    for x in range(1847, 3647, 2):
        for y in range(1920):
            draw.point((x, y), fill=rightColor())
            draw.point((x+1, y), fill=leftColor())
    image.save('mixRowColor.png','png')

def mixRowColumnColor():
    image = Image.new('RGB', (3648,1920), (255, 255, 255))
    draw = ImageDraw.Draw(image)
    for x in range(24, 1823, 2):
        for y in range(0, 1920, 2):
            draw.point((x, y), fill=leftColor())
    for x in range(24+1, 1823, 2):
        for y in range(0, 1920, 2):
            draw.point((x, y), fill=rightColor())
    for x in range(24, 1823, 2):
        for y in range(1, 1920, 2):
            draw.point((x, y), fill=rightColor())
    for x in range(24+1, 1823, 2):
        for y in range(1, 1920, 2):
            draw.point((x, y), fill=leftColor())
    for x in range(1847, 3647, 2):
        for y in range(0, 1920, 2):
            draw.point((x, y), fill=rightColor())
    for x in range(1847+1, 3647, 2):
        for y in range(0, 1920, 2):
            draw.point((x, y), fill=leftColor())
    for x in range(1847, 3647, 2):
        for y in range(1, 1920, 2):
            draw.point((x, y), fill=leftColor())
    for x in range(1847+1, 3647, 2):
        for y in range(1, 1920, 2):
            draw.point((x, y), fill=rightColor())
    image.save('mixRowColumnColor.png','png')

singleColor()
mixRowColor()
mixRowColumnColor()

上面的代码段只是临时用到的三种情况。可以使用python3直接测试查看。

使用最啰嗦的语句实现，没有任何的逻辑，只为实现。

后续继续学习的话，会逐渐对该程序进行更新。

如果出现下面的错误

ModuleNotFoundError: No module named 'PIL'

pip install pillow

如果因为电脑上安装不同的python版本，

python3 -m pip install pillow
