Componentee Svelte básico

<script>
  import PixuCompressor from 'pixu/components/svelte/PixuCompressor.svelte';

  function handleCompress(result) {
    console.log('Compressed:', result.detail);
  }
</script>

<PixuCompressor
  samples={sampleImages}
  options={{ quality: 0.85, format: 'image/pixu' }}
  on:compress={handleCompress}
/>

Com opções

<script>
  import PixuCompressor from 'pixu/components/svelte/PixuCompressor.svelte';
  import type { CompressionResult } from '@pantanal/pixu';

  const options = {
    quality: 0.8,
    maxWidth: 1920,
    maxHeight: 1080,
    format: 'auto',
    stripMetadata: true,
  };

  function handleCompress(event) {
    const result = event.detail;
    console.log('Compression completed:', result);
  }

  function handleError(event) {
    const error = event.detail;
    console.error('Error:', error);
  }

  function handleProgress(event) {
    const progress = event.detail;
    console.log('Progress:', progress);
  }
</script>

<PixuCompressor
  {options}
  on:compress={handleCompress}
  on:error={handleError}
  on:progress={handleProgress}
/>
