Angular 14 ngx-image-viewer Library to Build Image Editor to Drag,Zoom & Rotate Images in Browser Using TypeScript

Welcome folks today in this blog post we will be using the ngx-image-viewer library to build mini image editor to drag zoom 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-image-viewer

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

First of all you need to go to app.module.ts file and copy paste the following code

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { ImageViewerModule } from "ngx-image-viewer";

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    ImageViewerModule.forRoot()
  ],
  providers: [],
  bootstrap: [AppComponent]
})

export class AppModule{}

import { BrowserModule } from '@angular/platform-browser';

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

import { AppComponent } from './app.component';

import { ImageViewerModule } from "ngx-image-viewer";

@NgModule({

declarations: [

AppComponent

imports: [

BrowserModule,

ImageViewerModule.forRoot()

providers: [],

bootstrap: [AppComponent]

})

export class AppModule{}

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

app.component.html

<link rel="stylesheet" type="text/css"
  href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">
<div class="container">
  <div class="row">
    <div class="col">
      <div class="image-viewer-container" [class.fullscreen]="fullscreen">
        <div class="image-viewer">
          <ngx-image-viewer #imageViewer [src]="images" [(index)]="imageIndex"></ngx-image-viewer>
        </div>
      </div>
    </div>
  </div>
</div>

href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css">

<ngx-image-viewer #imageViewer [src]="images" [(index)]="imageIndex"></ngx-image-viewer>

</div>

As you can see in the above html code we are including the font-awesome cdn for the icons and then we have the ngx-image-viewer directive to embed the image-editor with controls as well to zoom and rotate images. And here we are attaching the images array which will hold the images to be edited in the image editor.

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

app.component.ts

import { Component, ViewChild } from '@angular/core';
import { ImageViewerComponent } from 'ngx-image-viewer';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css'],
})
export class AppComponent {
  @ViewChild('imageViewer')
  viewer!: ImageViewerComponent;

  fullscreen: boolean = false;
  imageIndex: number = 0;

  images: Array<string> = [
    'https://procodestore.com/wp-content/uploads/2021/03/164508084_271381191136191_654097929788476286_n.jpg',
    'https://freemediatools.com/img/profile.jpg'
  ];
}

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

import { ImageViewerComponent } from 'ngx-image-viewer';

@Component({

selector: 'app-root',

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

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

})

export class AppComponent {

@ViewChild('imageViewer')

viewer!: ImageViewerComponent;

fullscreen: boolean = false;

imageIndex: number = 0;

images: Array<string> = [

'https://procodestore.com/wp-content/uploads/2021/03/164508084_271381191136191_654097929788476286_n.jpg',

'https://freemediatools.com/img/profile.jpg'

];

}

As you can see in the above typescript code we have the images array where you need to store the url's of the images. And then we have also have other variables for fullscreen inside the image editor. And then we are declaring the reference of the image editor using the ViewChild decorator.
