Subject: Image from bytes streams
Hello!
I'm trying to get an array of bytes from graphic images generated by
R. Here, you can see my Java code:
--------------------------------------------------------------------------------------------------------------------------
Process p = Runtime.getRuntime().exec("C:/Arquivos de
programas/R/rw1090/bin/Rterm.exe --no-save");
DataOutputStream output = new DataOutputStream(new
BufferedOutputStream(p.getOutputStream()));
DataInputStream input = new DataInputStream(new
BufferedInputStream(p.getInputStream()));
// output.writeBytes("pie(c(50,30,20))"); //Pie graphic
output.writeBytes("plot(1,1)"); // Plot graphic
output.flush();
input.readFully(new byte[200]); // Here I read the "image" bytes.
--------------------------------------------------------------------------------------------------------------------------
That's the problem: when I use Pie graphic, I got some bytes. However,
when I use the Plot graphic, I got the same bytes! So, I suppose that
my program does not read the bytes from the generated graphic from R.
Is it possible to get the bytes from the generated graphic? How can I
get these bytes?
Sorry about my english. I'm brazilian! :)
