| 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. |
