converting an image to base64 in angular
// works like charm in pdfMake and angular
//You can use this function to create generate a base64 image
toDataURL = async (url) => {
console.log("Downloading image...");
var res = await fetch(url);
var blob = await res.blob();
const result = await new Promise((resolve, reject) => {
var reader = new FileReader();
reader.addEventListener("load", function () {
resolve(reader.result);
}, false);
reader.onerror = () => {
return reject(this);
};
reader.readAsDataURL(blob);
})
return result
};
// and then call it like this
imageSrcString = await this.toDataURL(imageSrc)
