Multiple clipping areas on Fabric.js canvas

Question

For making Photo Collage Maker, I use fabric js which has an object-based clipping feature. This feature is great but the image inside that clipping region cannot be scaled,

Answer 1

Update to previous guys answers.

ctx.rect(
    clipRect.oCoords.tl.x - this.oCoords.tl.x - clipRect.strokeWidth,
    clipRect.oCoords.tl.y - this.oCoords.tl.y - clipRect.strokeWidth,
    clipRect.oCoords.tr.x - clipRect.oCoords.tl.x,
    clipRect.oCoords.bl.y - clipRect.oCoords.tl.y
);

Now we are able to scale the clipping area without a doubt.
