Import the Module

In your Angular module, include the library:

export class AppModule {}

Use the Component

HTML

Add the cropper component to your template:

<cm-image-cropper
  [imageUrl]="selectedImage"
  [config]="cropperConfig"
  [aspectRatios]="aspectRatioOptions"
  (croppedImage)="onCroppedImage($event)"
></cm-image-cropper>

Component

Define the logic in your TypeScript file:

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  selectedImage: string | null = null;
  cropperConfig = {
    showCrop: true,
    showRotate: true,
    showFlip: true,
    showZoom: true,
    showBrightness: true,
    showContrast: true,
    showSaturation: true
  };
  aspectRatioOptions = [
    { label: 'Free', value: 0 },
    { label: '1:1', value: 1 },
    { label: '16:9', value: 16 / 9 }
  ];

  onCroppedImage(file: File): void {
    console.log('Cropped Image:', file);
  }

  onFileSelected(event: Event): void {
    const input = event.target as HTMLInputElement;
    if (input.files && input.files[0]) {
      const reader = new FileReader();
      reader.onload = () => {
        this.selectedImage = reader.result as string;
      };
      reader.readAsDataURL(input.files[0]);
    }
  }
}
