Hi, thanks for supporting the project. This option will be in the future. You can change the zoom ratio here: https://github.com/drozhzhin-n-e/ngx-pinch-zoom/blob/master/src/app/pinch-zoom/pinch-zoom.component.ts#L397

for example:
this.scale = this.initialScale * 3;
this.moveX = this.initialMoveX - (changedTouches[0].clientX * 2 - this.elementPosition.left);
this.moveY = this.initialMoveY - (changedTouches[0].clientY * 2 - this.elementPosition.top);

from ngx-pinch-zoom.

but this doesn't center the newly zoomed canvas properly, does it?

@kshantanu94 what coefficient do you want to use for scaling?

@kshantanu94 You can use the 'double-tap-scale' property to specify a scaling factor. 3f6d438
