python的帧缓冲模块 [英] Frame buffer module of python

问题描述

我正在寻找一个可以直接将jpg或png文件显示到/dev/fb0的python模块.

I'm looking for a python module which can display jpg or png file to /dev/fb0 directly.

我希望模块可以像这样调用并在屏幕上显示图片:

I hope the the module can call and display the picture on screen by like this:

show_photo(path_to_jpg, x, y, dev='/dev/fb0')

我已经在Google上搜索了这种python模块几天，然后找到了链接:

I had searched such kind of python module on google for several days, and I found the link: [Module] Python Frame Buffer, but the website was not found.

现在，我正在使用C程序并通过os.system()函数进行调用，它太慢了.是否有一个python模块可以将图片直接显示到帧缓冲区，并支持静态图片，字幕?如果模块还支持播放mplayer之类的视频文件会更好.

Now, I'm using C program and call by os.system() function, and it is too slow. Does there has a python module which can show the picture directly to frame buffer, and support static picture, marquee? It will be better if the module also support playing video file like mplayer.

推荐答案

也许您可以使用pygame.

Maybe you may use pygame.

http://www.pygame.org/wiki/about

Pygame使用opengl，directx，windib，X11， Linux帧缓冲区， 以及许多其他不同的后端...

Pygame uses either opengl, directx, windib, X11, linux frame buffer, and many other different backends...

更新: 简单的例子:

import pygame
import sys
import time

pygame.init()

size = (pygame.display.Info().current_w, pygame.display.Info().current_h)
black = 0, 0, 0

screen = pygame.display.set_mode(size)

ball = pygame.image.load("ball.gif")
ballrect = ball.get_rect()

screen.fill(black)
screen.blit(ball, ballrect)
pygame.display.flip()

time.sleep(5)

运行:

SDL_NOMOUSE=1 python ./ball.py
