Thanks! This help-me to understand canvas component workings. Chrome working in different form:
function blobCallback(filename) {
return function(obj) {
window.download(obj, filename);

}
}
imgcanvas.toBlob(blobCallback("file"), null, 0.95);

I have a such problem "Tainted canvases may not be exported", how to fix it?

[PhoenixRiseMotivation]

How can we automatically upload all the generated image to the wordpress media library?

[Horse-tradeEu]

cool video. I already achieved that and next step is to be able to share in social media. Ideally with no back end and no external service. Any ideas?
