Hi All
Appreciate answers. Any way what I am looking for in write base64 encoded
image binary data to a file. And these answers won't satisfy my answers.
Initially I checked for the options available in jaggery to cater my
requirement. But after the chat had with Manu it seems that Jaggery have
some problem with the requirement and they are working on it.
Any way I tried to do it from the java script and I used the following
code. Still I have no idea how to write this blob to a File with jaggery.
Manu can you check this?
var data = atob(imageData.replace(/^data:image\/\w+;base64,/, ""));
console.log(data);
var uint8Array = new Uint8Array(data.length);
for( var i = 0, len = data.length; i < len; ++i ) {
uint8Array[i] = data.charCodeAt(i);
}
var blob = new Blob( [ uint8Array.buffer ], {type: "image/jpg"} );
Thanks & Regards
