[英]Download canvas as image not working in firefox and microsoft edge
我想下載canvas作為圖像,但不是在firefox和microsoft邊緣工作但使用chrome
這是我的代碼:
DownloadImage = (i) => {
var _this = this;
this.modeler.saveSVG(function (err, svg) {
if (err) console.log(err)
_this.setState({ datasvg: svg }, function () {
const canvas = _this.refs.canvasforimage;
const options = {
log: false,
ignoreMouse: true,
};
canvg(canvas, this.state.datasvg, options);
const image = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream");
const element = document.createElement("a");
element.setAttribute('download', 'diagram.png');
element.setAttribute('href', image);
element.click();
有什么解決方案嗎?
這是我用來將畫布內容保存為PNG圖像文件的代碼:
canvas.toBlob(blob => {
var a = document.createElement("a"),
url = URL.createObjectURL(blob);
a.href = url;
a.download = "image.png";
document.body.appendChild(a);
a.click();
setTimeout(function() {
document.body.removeChild(a);
window.URL.revokeObjectURL(url);
}, 0);
});
