Braden Shepherdson commented on CB-1045:
----------------------------------------
Base64 image data may be obtained from the returned URL in Javascript. If you
create an image, set its src to the URL, and then in onload create a canvas,
size it, draw the image to it, and extract the base64 with toDataURL. See code:
{code:javascript}
navigator.contacts.find(['displayName', 'photos'],
function(contacts) {
console.log('Found ' + contacts.length + ' contacts.');
for (var i = 0; i < contacts.length; i++) {
if (contacts[i].photos) {
for (var j = 0; j < contacts[i].photos.length; j++) {
var img = new Image();
img.onload = function() {
var canvas = document.createElement("canvas");
canvas.width = img.width;
canvas.height = img.height;
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0);
try {
var data = canvas.toDataURL("image/png");
// data == "data:image/png;base64,BASE64_DATA_HERE..."
} catch(e) {
console.log('toDataUrl failed: ' + e);
}
};
try {
console.log('trying to set img.src to ' +
contacts[i].photos[j].value);
img.src = contacts[i].photos[j].value;
console.log('img.src = ' + img.src);
} catch (e) {
console.log('failed to load image: ' + e);
}
}
}
}
}, function(err) {
alert(err);
});
