Chrome Console Error And Mask Not Working #9

Open dada78 opened 5 years ago

dada78 commented 5 years ago

I downloaded the example files but the masks aren't showing when viewing in the latest Chrome (Mac). I get a console error:"Uncaught DOMException: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported. at HTMLImageElement.mask.onload (file:///Users/cfuller1/Downloads/canvas-masking-master/canvasmask.js:28:33"

No problem in Firefox. Any idea what the issue is? Thanks~

Yes, you can’t do that on a file:// url, it needs to be on a https:// one.

I see. I thought it would a cross domain issue and enabled CORS on Chrome but wasn't working, but yeah works on server. Thanks!
