[~vladimir.kotikov] Please find below code snippet used in my application. As I
mentioned earlier, JPG images are getting attached but not PNG. Also I tried
there is no reason for error received in _image.onerror_.
{code}
$('#btnGallery').click(function () {
getPhoto(navigator.camera.PictureSourceType.SAVEDPHOTOALBUM);
});
function getPhoto(source) {
navigator.camera.getPicture(function (imageURI) {
addLoader();
onPhotoURISuccess(imageURI);
}, CameraFail, {
quality: 35,
destinationType: navigator.camera.DestinationType.FILE_URI,
saveToPhotoAlbum: false,
sourceType: source,
allowEdit: false,
targetWidth: 600,
targetHeight: 800
});
}
function onPhotoURISuccess(imageURI) {
// converts the image to a 2d canvas
canvasimage(imageURI);
}
function canvasimage(src) {
var canvas = document.createElement("canvas");
var ctx = canvas.getContext("2d");
var imgdata = new Image;
imgdata.onload = function () {
canvas.width = this.width;
canvas.height = this.height;
ctx.drawImage(this, 0, 0);
dataURL = canvas.toDataURL('image/jpeg');
var blob = dataURItoBlob(dataURL);
gotfilesystem(blob);
}
imgdata.onerror = function () {
alert('error');
}
imgdata.src = src;
}
function dataURItoBlob(dataURI) {
// convert base64/URLEncoded data component to raw binary data held in a
string
var byteString;
if (dataURI.split(',')[0].indexOf('base64') >= 0)
byteString = atob(dataURI.split(',')[1]);
else
byteString = unescape(dataURI.split(',')[1]);
// separate out the mime component
var mimeString = dataURI.split(',')[0].split(':')[1].split(';')[0];
// write the bytes of the string to a typed array
var ia = new Uint8Array(byteString.length);
for (var i = 0; i < byteString.length; i++) {
ia[i] = byteString.charCodeAt(i);
}
return new Blob([ia], { type: mimeString });
}

[~sadiqmc] Which cordova platform are you using? Is that WP8 or Windows
platform? Also please elaborate what does mean "I cant able to load the .png
image selected from gallery"? Are you getting any errors or your code isn't
working as expected?
Please also specify your cordova, platforms and plugins versions - you can get
them via {{cordova --version && cordova platform ls && cordova plugin ls}}
