python - 调整 PyGame 屏幕大小
问题描述
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
问题
需要进行哪些更改才能正确调整图像流窗口的大小?
提前致谢。

解决方案
您最近的 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分辨率:
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的大小。
