I am trying to send an image from Socket server (Java) to socket client (Python) but the received image in client has an incorrect size and does not open. I don't know what am I doing wrong. Any suggestions?
Server (Java):
...
BufferedImage image = ImageIO.read (new File("c:\\tmp\\File.png"));
ImageIO.write(image, "png", connectionSocket.getOutputStream());
...
Client (Python):
try:
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
client_socket.connect( host , port )
data = client_socket.recv( 1024 )
fp = open ( path, "wb" )
while data:
data = client_socket.recv( 1024 )
if data:
if not data: break
fp.write ( data )
fp.flush()
fp.close()
client_socket.close()
except:
print "could not connect to %s:%s " %( host, port
Convert your image to a base64 string (Java), then transfert the string and get back to the image data (python).
In java, to get Image from base64 string:
public static Image image(String base64Img) {
byte[] b = DatatypeConverter.parseBase64Binary(base64Img);
ByteArrayInputStream s = new ByteArrayInputStream(b);
return new Image(s);
}
