Hi, thanks for the issue. I don't spend much time on this library anymore nor do I have the time for. Therefore cannot help sorry. I fear you will not get much support but for sure the issue can remain open.

The problem is this

E/Capacitor: Unable to open asset URL: http://localhost/webphotofilter.js

Angular.json is not producing this file on compilation.

Hi @aliexalter I know this was long ago but were you able to fix this issue in the end ? I'm facing it right now using Angular 15 and Ionic 6

[aliexalter]

Yes by using Instagram css filters. I use css filters to only display filtered image. Once user finalise the filter using javascript I apply the filter again to base64 original image.

Thank you! I'm going to try that out
