How to convert image to binary file/stream in adobe acrobat pro?

Trying to clarify... you want to import an image, convert it to a base64 string and then set the value of a barcode field so that when the barcode is later scanned, you can interpret the barcode data as an image.

Did I get that right?

This is not possible.

Tried to convert the uploaded image to binary stream under button click so as to embed to bar code and to fetch the image while reading.But the stream data is coming as alert.

// JScript source code

var pathFile = "E:/Adobe/PDF/Images/home.jpg";

app.alert(pathFile);

this.importIcon("myIcon", pathFile, 0);

var oIcon = util.iconStreamFromIcon(this.getIcon("myIcon"));

app.addToolButton({

    cName: "btnTest",

    oIcon: oIcon,

    cExec: "console.println('My Button!');",

    cTooltext: "Test!",

    nPos: 0

});

app.alert("b");

app.alert(oIcon);
