Work in web worker about node-pureimage HOT 4 CLOSED

The library doesn't use anything Node specific, so I think it would run in a web worker. I've never tried. However, it is significantly slower than real canvas, so I'm not sure it would work for your use case. What are you trying to accomplish by using a web worker?

from node-pureimage.

Inside web worker I will need such functions:

    ctx.beginPath();
    ctx.strokeStyle = 'rgb(0,0,255)';
    ctx.moveTo(x1,y1);
    ctx.lineTo(x2, y2);
    ctx.stroke();

And as a result:
canvas.toDataURL();
or
ctx.getImageData();

Looks like your library does not have such functions, does it?

No, my library does not have such functions, but I think it would be easy to add. The data is stored in an internal bitmap array. It wouldn’t be hard to expose that as the ImageData object that ctx.getImageData() returns. Probably easier than implementing toDataURL();
