pygame多种方式实现屏保操作(自动切换、鼠标切换、键盘切换),欢迎往下观看。
一、图片处理
(一)图片采集
我认为有三种方法:
其一:使用爬虫技术从网上下载图片,可以开一个子线程负责采集网上图片,然后加载到list列表中;
其二:可以直接对电脑中所有的盘进行自动检索,然后加载到list列表中;
其三:指定目录,然后加载到list列表中;
我这里偷个懒,选择第三种方法实现。具体代码如下:
1

|
path = './image/' files = [] dirs = os.listdir(path) for diretion in dirs: files.append(path + diretion) |
(二)图片装载
我为什么在初始化的时候就进行装载呢?
原因是:解决效率问题,无需每次使用时重复加载,而且在初始化的时候就适配屏幕大小进行图片缩放。
因此,我把这个过程打包成一个函数,方便后续调用,而且参数传递为:屏幕的大小。然后返回bglist对象。

for file in files: picture = pygame.transform.scale(pygame.image.load( file ), ( 1440 , 900 )) dSurface = picture # dSurface = pygame.image.load(file).convert() bglist.append(dSurface) |
(三)完整代码
封装成函数:

def init_image(): path = './image/' files = [] dirs = os.listdir(path) for diretion in dirs: files.append(path + diretion) for file in files: picture = pygame.transform.scale(pygame.image.load( file ), ( 1440 , 900 )) dSurface = picture # dSurface = pygame.image.load(file).convert() bglist.append(dSurface) |
二、初始化pygame相关参数
(一)设置初始化参数

pygame.init() # 初始化pygame类 # 设置窗口大小 pygame.display.set_caption( '美丽的屏保' ) # 设置窗口标题 tick = pygame.time.Clock() fps = 10 # 设置刷新率,数字越大刷新率越高 fcclock = pygame.time.Clock() bglist = [] flag = 0 runimage = None |
(二)设置为全屏显示:
1
|
screen = pygame.display.set_mode(( 1440 , 900 ),flags = pygame.FULLSCREEN) |
三、核心模块
(一)自动切换

def run(): flag = 0 runimage = random.choice(bglist) while True : for event in pygame.event.get(): if event. type = = pygame.QUIT: sys.exit() screen.fill(( 255 , 255 , 255 )) # 设置背景为白色 screen.blit(runimage.convert(), ( 0 , 0 )) if flag % 100 = = 1 : runimage = random.choice(bglist) flag + = 1 fcclock.tick(fps) pygame.display.flip() # 刷新窗口 |
(二)键盘切换

for event in pygame.event.get(): if event. type = = pygame.KEYDOWN: if event.key = = pygame.K_ESCAPE: pygame.quit() sys.exit() if event.key = = pygame.K_SPACE: reset() |
(三)鼠标切换
1

|
for event in pygame.event.get(): if event. type = = pygame.MOUSEBUTTONDOWN: reset() |
(四)退出操作
1

3
4
|
for event in pygame.event.get(): if event. type = = pygame.QUIT or event. type = = pygame.K_F1: pygame.quit() sys.exit() |
(五)设置透明色
1
|
runimage.set_alpha( 255 - flag * 2 ) |

def run(): global flag,runimage runimage = random.choice(bglist) while True : for event in pygame.event.get(): if event. type = = pygame.QUIT or event. type = = pygame.K_F1: pygame.quit() sys.exit() if event. type = = pygame.KEYDOWN: if event.key = = pygame.K_ESCAPE: pygame.quit() sys.exit() if event.key = = pygame.K_SPACE: reset() if event. type = = pygame.MOUSEBUTTONDOWN: reset() screen.fill(( 255 , 255 , 255 )) # 设置背景为白色 screen.blit(runimage, ( 0 , 0 )) if flag % 100 = = 1 : reset() flag + = 3 runimage.set_alpha( 255 - (flag * 2 ) % 250 ) fcclock.tick(fps) pygame.display.flip() # 刷新窗口 |
四、其他相关函数:
(一)reset函数
1

|
def reset(): global flag,runimage flag = 0 runimage = random.choice(bglist) |
(二)main函数

if __name__ = = '__main__' : init_image() run() |
