phoboslab / js-hqx Goto Github PK

Using test.html via file:/// 'protocol' doesn't work due to violated cross-origin policy (I think). Does this only work when run from a server or localhost?

Web Inspector error log (using Chrome 21.0.1180.82):

Unable to get image data from canvas because the canvas has been tainted by cross-origin data.

Uncaught Error: SECURITY_ERR: DOM Exception 18 hqx.js:185

window.hqx hqx.js:185
loaded index.html:8
onload index.html:15

How could use it for html js-hqx?

Hi,

Did you think about using a WebWorker instead of the main thread?
Did you try using a WebGL shader to pass the calculation to the GPU?
Did you compare hqx with xbr (or xbrz)?

Thanks
