python3 4行代码实现图片分辨率转换，需要用到PIL

Jun

自己写的

def imgresize(filename):
    a.resize((720, 1280), Image.ANTIALIAS).save('%s-720x1280.png' % filename[:-4])
    print('转换完毕，图片名为：', '%s-720x1280.png' % filename[:-4])
    return '%s-720x1280.png' % filename[:-4]

def screencut(stage, jietu):
    # jietu.crop((74, 215, 123, 264)).save('fenge/stage.png')  识别不出来，所以手动输入stage吧
    if 0 < stage < 8:
        r1 = jietu.crop((40, 320, 160, 380)).save('fenge/r1.png')
        r2 = jietu.crop((40, 420, 160, 480)).save('fenge/r2.png')
        r3 = jietu.crop((40, 520, 160, 580)).save('fenge/r3.png')
        r4 = jietu.crop((40, 620, 160, 680)).save('fenge/r4.png')
        r5 = jietu.crop((40, 720, 160, 780)).save('fenge/r5.png')
        c1 = jietu.crop((200, 180, 230, 305)).save('fenge/c1.png')
        c2 = jietu.crop((300, 180, 335, 305)).save('fenge/c2.png')
        c3 = jietu.crop((400, 180, 435, 305)).save('fenge/c3.png')
        c4 = jietu.crop((500, 180, 535, 305)).save('fenge/c4.png')
        c5 = jietu.crop((600, 180, 660, 300)).save('fenge/c5.png')
    elif 8 < stage < 10:
        r1 = im.crop((70, 440, 260, 1300))
    elif 10 < stage < 13:
