Componente Angular básico

import { Component } from '@angular/core';
import { PixuCompressorComponent } from 'pixu/components/angular/pixu-compressor.component';
import type { CompressionResult } from '@pantanal/pixu';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [PixuCompressorComponent],
  template: `
    <pixu-compressor
      [samples]="sampleImages"
      [options]="{ quality: 0.85, format: 'image/pixu' }"
      (compress)="handleCompress($event)"
    ></pixu-compressor>
  `
})
export class AppComponent {
  handleCompress(result: CompressionResult) {
    console.log('Compressed:', result);
  }
}

Com opções
