Is it possible to use this as input?

`sharp(path.join(picture.path, picture.name))
 .clone()
   .resize(Number(imgWidth), Number(imgHeight))
    .extract({ 

      left  : Math.round(left  )

    , top   : Math.round(top   )

    , width : Math.round(width )

    , height: Math.round(height)

    })
`

It is just a while image of dimension 3393*1713.

Hello,

I've been trying to use image-to-slices with images from different domain. The images served by the server do have the Access-Control-Allow-Origin * header. However I still get the error:
Uncaught DOMException: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': The canvas has been tainted by cross-origin data when clipper crop calls getImageData
The way I call ImageToSlices is the following
var imageToSlice = new Image(); imageToSlice.onload = function () { ImageLoaded(imageToSlice); } imageToSlice.crossOrigin = "anonymous"; imageToSlice.src = imageUrlInOtherDomain + '?' + new Date().getTime();

Inside ImageLoaded I call
imageToSlices(imageToSlice.src, xGuides, yGuides, { saveToDataUrl: true, clipperOptions: { imageFormat: imageFormat } }, function (dataUrlList) { saveSlices(dataUrlList); }); }

Is it possible to pass the object imageToSlice which already has the attribute crossOrigin instead of imageToSlice.src? Could you give an example of how to correctly use image-to-slices with CORS?

Can we change name of images ??

So I have a Telegram bot that makes screenshots of a site with puppeteer, but they turn out too long, so I decided to slice them with image-to-slices. After installing both canvas and image-to-slices (image-clipper is present as well) when I run the script, it throws this error:

Error: Require node-canvas on the server-side Node.js

Can anyone help please? Would be cool to know what causes this.

I am working with really large images that I wish to tile at 256 * 256 tiles, thus means large arrays of slices i.e at least 20 * 20.

If I slice in large slices there are no issues but if i slice in 256px tiles i get a segfault:

Process finished with exit code 139 (interrupted by signal 11: SIGSEGV)

Is anyone else seeing this issue and have they been able to get around from what I can see it is 1 of 3 things:

1. ran out of memory
2. allocation of the array of the slices are incorrect
3. The image should have been previously closed and wasnt.

Any pointers would be great.
