Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

var bd = new CkBinData();

success = bd.LoadFile("qa_data/jpg/starfish.jpg");
if (success == false) {
    console.log("Failed to load file.");
    return;
}

// For example, let's say we want construct simple JSON containing the base64 representation of the above JPG file.
var sb = new CkStringBuilder();
sb.Append("{ \"jpg\": \"");
// GetEncodedSb appends the enocded representation of the binary data to the StringBuiler passed in the 2nd arg.
bd.GetEncodedSb("base64",sb);
sb.Append("\" }");

console.log(sb.GetAsString());

// Output looks like this:
//  { "jpg": "/9j/4AAQSkZJRgABAg...rcQ+vo//2Q==" }
