implementing image upload with crop and zooming in Angular involves a few steps. We’ll use the popular library called ng2-img-cropper for this purpose. Here’s a step-by-step guide:
Note: If you went to create a new Angular project you can see my another blog ‘How to create Angular project’, also you can follow below steps
Step 1: Install ng2-img-cropper
Open a terminal and run the following command to install ‘ng2-img-cropper’:
npm install ng2-img-cropper --save
Step 2: Import and Configure Module
In your Angular module file (usually ‘app.module.ts’), import ‘ImageCropperModule’ from ‘ng2-img-cropper’:
// app.module.ts import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { FormsModule } from '@angular/forms'; import { ImageCropperModule } from 'ng2-img-cropper'; import { AppComponent } from './app.component'; @NgModule({ declarations: [ AppComponent, ], imports: [ BrowserModule, FormsModule, ImageCropperModule, ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }
Step 3: Create Component
Create an Angular component that will handle the image upload and cropping. Here’s a basic example:
// image-upload.component.ts import { Component, OnInit } from '@angular/core'; import { ImageCroppedEvent } from 'ngx-image-cropper'; @Component({ selector: 'app-image-upload', templateUrl: './image-upload.component.html', styleUrls: ['./image-upload.component.css'] }) export class ImageUploadComponent implements OnInit { imageChangedEvent: any = ''; croppedImage: any = ''; constructor() { } ngOnInit(): void { } fileChangeEvent(event: any): void { this.imageChangedEvent = event; } imageCropped(event: ImageCroppedEvent) { this.croppedImage = event.base64; } imageLoaded() { // Image loaded callback } cropperReady() { // Cropper ready callback } loadImageFailed() { // Image load failed callback } }
Step 4: Create HTML Template
Create the HTML template for your component (‘image-upload.component.html’):
Step 5: Style the Component
You may want to add some styles to your component (‘image-upload.component.css’):
/* image-upload.component.css */ input { margin-bottom: 20px; } img { max-width: 100%; height: auto; margin-top: 20px; }
Step 6: Use the Component
Now, you can use your newly created ‘ImageUploadComponent’ in your existing Angular application. For example, you can add it to the main app component:
// app.component.ts import { Component } from '@angular/core'; @Component({ selector: 'app-root', template: '', styleUrls: ['./app.component.css'] }) export class AppComponent { }
Step 7: Run Your Application
Run your Angular application using the following command:
ng serve
Visit ‘http://localhost:4200/’ in your browser, and you should see your image upload component with crop and zoom functionality.
That’s it! You’ve successfully implemented image upload with crop and zoom in Angular using ‘ng2-img-cropper’. Customize the component and styles as needed for your project.
