How to reset preview

[phamtranquocviet]

Hi,
After loading the image, I need to a) crop, b) save it, c) crop again from the same image, and d) save again. After the first save, I need to clear the preview. How do I do that?

I successfully use ViewChild to get to the img element and clear src attribute. The cropped image did go away. However, cropping the next image (step c above) does not show the cropped image in the preview any more.

Any idea how to reset the preview?
Thanks.

Try hide then show like this

at ts file
this.ratio=false;
setTimeout(() => {
this.ratio=true;
}, 50);
