我使用的命令是:
C:\cmd\ffmpeg\bin\ffmpeg.exe -i "C:\Users\user\Dropbox\Workspace - C#\SnowflakeGenerator\out\out%d.png" -c:v libvpx -b:v 1M "C:\Users\user\Dropbox\Workspace - C#\SnowflakeGenerator\video.webm" -y
输出是:

libavutil 55. 43.100 / …我可以加载整个图像并轻松使用它们
pygame.image.load("image.png")
但如果我只想要一小部分，我必须加载整个图像并从那里裁剪。
pygame 有没有办法有效地仅加载图像的一部分？
