I made a tsp which decode Image to base64 byte array String.
It works in Chrome and Firefox. However in safari 8.0, it does not work.
My jsp looks like below :
String sFileInfo = "";
String name = request.getHeader("file-name");
String ext = name.substring(name.lastIndexOf(".")+1);
InputStream is = request.getInputStream();
byte b[] = IOUtils.toByteArray(is);
String base64DataString = Base64.encodeBase64String(b);
base64DataString = "data:image/" + ext + ";base64," + base64DataString;
if(is != null) {
is.close();
}
And as result code below will be attached to browser.

I copy this code(part of after base64;
) and put link below in safari.
http://base64online.org/decode/
and I got an image, so I assume that Safari also support base64 image.
However, when I put this on web with image tags, it does not work.
Thanks for answer :D
PS browser error message is
Failed to load resource: (kCFErrorDomainCFNetwork error -10.)
I know this question is pretty old but I've recently faced a similar problem on iOS' safari, and the problem seems to be that Safari will not render base64 images that does not have a number of character divisible by 4.
The solution to this problem is to pad your encoded string at the end using '=' characters. Here is a basic algorithm:
// b64str = 's/3eea4sp...' (or any base 64 encoded string)
while (b64str.length % 4 > 0) {
b64str += '=';
}
Hope this helps someone !
I was in a similar situation but the posted solution did not work for me. But I did come up with an alternative solution after some trial and error. Hope this helps out.
// Add an actual base64 string
var encodedImgString = 'data:image/png;base64,iVBORw0KGgoAAA...';
// Create an image, set img source and cross origin attribute
var iosImg = new Image;
iosImg.src = encodedImgString;
iosImg.crossOrigin = 'Anonymous';
// Change this to target your element and add it wherever you need it to appear
document.body.appendChild(iosImg);
