Android MonkeyImage到二进制

android ruby sockets android-emulator

Android MonkeyImage到二进制,android,ruby,sockets,android-emulator,monkeyrunner,Android,Ruby,Sockets,Android Emulator,Monkeyrunner,我正在实现使用Android MonkeyImage拍摄Emulator的屏幕截图。捕获的数据通过TCPSocket发送到Ruby脚本，并尝试将其保存为jpg图像。但是我不知道如何用Ruby将发送的字符串数据转换成二进制。代码如下 [client.py] from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice, MonkeyImage import socket import sys import base64 s

我正在实现使用Android MonkeyImage拍摄Emulator的屏幕截图。捕获的数据通过TCPSocket发送到Ruby脚本，并尝试将其保存为jpg图像。但是我不知道如何用Ruby将发送的字符串数据转换成二进制。代码如下

[client.py]

from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice, MonkeyImage
import socket
import sys
import base64

server_address = ('localhost', 9898)
print >>sys.stderr, 'connecting to %s port %s' % server_address

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(server_address)

device = MonkeyRunner.waitForConnection(60 , "emulator-5554")

while True:

    sc   = device.takeSnapshot().convertToBytes("jpg")
    size = str(len(sc)).zfill(16)

    sock.sendall(size)
    sock.sendall(sc)

    print >>sys.stderr, 'sended'

sock.close()

[server.rb]

#!/usr/bin/ruby                                                                 
# coding: utf-8                                                                 
require "socket"

s0 = TCPServer.open(9898)
sock = s0.accept
count = 0
loop do

  size  = sock.recv(16).to_i
  image = sock.recv(size)

  File.open("/Users/taicsuzu/Downloads/ss4/test"+count.to_s+".jpg", "wb") do |file|                                                  
    #file.write(image.unpack("B*"))[0]
    #file.write(image)                                          
    #file.write(image.encode("BINARY"))                                                          
  end

  p image
  count += 1

end
sock.close
s0.close

    sock.sendall(size)
    sock.sendall(sc)

    print >>sys.stderr, 'sended'

sock.close()

如何将ascii字符串数据转换为图像二进制？注释掉的行（file.write（）…）不工作，生成无效图像或黑色图像。谢谢你的帮助

您可以通过

dump

命令行实用程序或使用

culebra

生成的python脚本来获取屏幕截图

首先，命令行

$ dump -Df ~/tmp/sc1.png

dump

没有将屏幕截图保存为JPEG的选项，因为它们通常保存为PNG（但可能是一个不错的添加）

另一方面，通过

culebra

自动生成的python脚本，我通过JPEG手动编辑PNG
