Save (Download) Images to Folder in Angular

Hi,

I am trying to save an image in my local drive, it will show the file but when i open it, it says it cant be displayed.

const dlink: HTMLAnchorElement = document.createElement('a');
dlink.download = droppedFile.relativePath; // the file name
dlink.href = 'data:text/plain;charset=utf-16,';
dlink.click(); // this will trigger the dialog window
dlink.remove();
