Angular 14 ngx-photo-editor Example to Build Image Editor With Live Preview to Crop,Scale & Rotate inside Browser Using TypeScript

Welcome folks today in this blog post we will be using the ngx-photo-editor library to build image editor with live preview to crop,scale and rotate images using typescript in browser. All the full source code of the application is shown below.

Get Started

In order to get started you need to make a new angular project using the below command as shown below

ng new sampleproject

cd sampleproject

And after that you need to install the below libraries using the below command as shown below

npm i ngx-photo-editor

And after that you will see the below directory structure of the angular app as shown below

And now you need to go to angular.json file of your angular project and copy paste this below css line of the library inside the styles section as shown below

angular.json

"styles": [
  "src/styles.css",
  "node_modules/ngx-photo-editor/photo-editor.css"
],

"styles": [

"src/styles.css",

"node_modules/ngx-photo-editor/photo-editor.css"

And now we need to go to app.component.html file and copy paste the following code

app.component.html

<input type="file" (change)="fileChangeHandler($event)">
<img [src]="output?.base64" alt="">

1 2	<input type="file" (change)="fileChangeHandler($event)"> <img [src]="output?.base64" alt="">

As you can see in the above html code we have the input field element where we allow the user to select the image file and then we have the image displayed with live preview using the base64 code of the image.

And now we need to go to app.component.ts file and copy paste the below code

app.component.ts

import { Component } from '@angular/core';
import { NgxCroppedEvent,NgxPhotoEditorService } from 'ngx-photo-editor';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
})
export class AppComponent {
  title = 'angular image editor';

  output?: NgxCroppedEvent;

  constructor(private service: NgxPhotoEditorService) {}

  fileChangeHandler($event: any) {
    this.service.open($event, {
      aspectRatio: 4 / 3,
      autoCropArea: 1
    }).subscribe(data => {
      this.output = data;
    });
  }
}

import { Component } from '@angular/core';

import { NgxCroppedEvent,NgxPhotoEditorService } from 'ngx-photo-editor';

@Component({

selector: 'app-root',

templateUrl: './app.component.html',

styleUrls: ['./app.component.css'],

})

export class AppComponent {

title = 'angular image editor';

output?: NgxCroppedEvent;

constructor(private service: NgxPhotoEditorService) {}

fileChangeHandler($event: any) {

this.service.open($event, {

aspectRatio: 4 / 3,

autoCropArea: 1

}).subscribe(data => {

this.output = data;

});

}

As you can see in the above typescript code we are importing the ngx-photo-editor module at the very top and then we are passing the ngxPhotoEditor Service inside the constructor. And then we are defining the method that we have binded on the input field inside it we are using the open() method of the image editor to show the image inside the modal editor to perform the operations such as crop,scale and rotate as shown below.
