Name

### loadBytes()

Examples

    // open a file and read its binary data
    byte b[] = loadBytes("something.dat");

    // print each value, from 0 to 255
    for (int i = 0; i < b.length; i++) {
      // every tenth number, start a new line
      if ((i % 10) == 0) {
        println();
      }

      // bytes are from -128 to 127, this converts to 0 to 255
      int a = b[i] & 0xff;
      print(a + " ");
    }
    // print a blank line at the end
    println();

Description

Reads the contents of a file or url and places it in a byte array. If a file is specified, it must be located in the sketch's "data" directory/folder.
The filename parameter can also be a URL to a file found online. For security reasons, a Processing sketch found online can only download files from the same server from which it came. Getting around this restriction requires a signed applet.

Syntax

    loadBytes(filename);

Parameters

filename | String: name of a file in the data folder or a URL.

Returns | byte[]
Usage | Web & Application
