调整 PyGame 屏幕大小

如何解决调整 PyGame 屏幕大小

问题

基本上我有这个代码来流式传输桌面屏幕。问题是，当我尝试调整服务器屏幕的大小（服务器将接收图像）时，图像保持剪切/扭曲

我尝试调整窗口大小：

应该是什么（模拟）：

问题

正确调整图像流窗口的大小需要进行哪些更改？

提前致谢。

解决方法

您在最近的 pastebin 中的代码几乎是正确的，但就像我说的，您必须分别存储服务器和客户端解析：

import socket
from zlib import decompress
import pygame
 
def recvall(conn,length):
    """ Retreive all pixels. """
    buf = b''
    while len(buf) < length:
        data = conn.recv(length - len(buf))
        if not data:
            return data
        buf += data
    return buf
 
 
def main(host='192.168.15.2',port=6969):
    ''' machine lhost'''
    sock = socket.socket()
    sock.bind((host,port))
    print("Listening ....")
    sock.listen(5)
    conn,addr = sock.accept()
    print("Accepted ....",addr)
 
    client_resolution = (conn.recv(50).decode())
    client_resolution = str(client_resolution).split(',')
    CLIENT_WIDTH = int(client_resolution[0])
    CLIENT_HEIGHT = int(client_resolution[1])
    
    #store the server's resolution separately
    SERVER_WIDTH = 1000
    SERVER_HEIGHT = 600
 
    pygame.init()
 
    screen = pygame.display.set_mode((SERVER_WIDTH,SERVER_HEIGHT))
 
    clock = pygame.time.Clock()
    watching = True
 
    try:
        while watching:
            for event in pygame.event.get():
                if event.type == pygame.QUIT:
                    watching = False
                    break
 
            # Retreive the size of the pixels length,the pixels length and pixels
 
            size_len = int.from_bytes(conn.recv(1),byteorder='big')
            size = int.from_bytes(conn.recv(size_len),byteorder='big')
            pixels = decompress(recvall(conn,size))
 
            # Create the Surface from raw pixels
            img = pygame.image.fromstring(pixels,(CLIENT_WIDTH,CLIENT_HEIGHT),'RGB')            
            
            #resize the client image to match the server's screen dimensions
            scaled_img = pygame.transform.scale(img,(SERVER_WIDTH,SERVER_HEIGHT))

            # Display the picture
            screen.blit(scaled_img,(0,0))
            pygame.display.flip()
            clock.tick(60)
    finally:
        print("PIXELS: ",pixels)
        sock.close()
 
 
if __name__ == "__main__":
    main()  

请注意，您可以随时更改服务器的分辨率，完全独立于客户端的分辨率。这意味着您甚至可以根据需要调整窗口大小。
