I used html2canvas library. I want to store the image using the html2canvas. I success to store image from html2canvas!!! WOW!!! but.... IE has failed... I want to store all of browser.
I find navigator.msSaveBlob... I was happy~ but the happiness did not last long... base64 Encording Image is String! but I want to store pngfile! help me!!! (PS. I seriously want to slap a strong chest of IE)
~this is code~
html2canvas($("body")[0], {
onrendered: function(canvas) {
var img = canvas.toDataURL("image/png");
var img2 = img.split("data:image/png;base64,")[1];
//var blobObject = new Blob([img2],{type:"image/jpeg"});
var blobObject = new Blob([img2]);
window.navigator.msSaveBlob(blobObject, 'test.png'); // The user only has the option of clicking the Save button.
alert('File save request made using msSaveBlob() - note the single "Save" button below.');
}
});
The sad answer is... :-((
Chrome & Firefox have supported canvas.toBlob
for a while, but...
IE & Edge don't yet natively support canvas.toBlob
But there are nice polyfills that bring .toBlob
to IE/Edge.
I like Eli Grey's FileSaverJS and his canvas-toBlobJS .
BlueImp's JavaScript-Canvas-to-Blob is popular, too.
