Componentee React básico

import React from 'react';
import PixuCompressor from 'pixu/components/react/PixuCompressor';
import 'pixu/components/react/PixuCompressor.css';

const sampleImages = [
  { id: 'landscape', label: 'Mountains', url: '/photo-landscape.jpg', file: 'photo-landscape.jpg' },
];

function App() {
  return (
    <PixuCompressor
      samples={sampleImages}
      options={{ quality: 0.85, format: 'image/pixu' }}
      onCompress={(result) => {
        console.log('Compressed:', result);
      }}
    />
  );
}

export default App;

Com opções

import React from 'react';
import PixuCompressor from 'pixu/components/react/PixuCompressor';
import 'pixu/components/react/PixuCompressor.css';
import type { CompressionResult } from '@pantanal/pixu';

function App() {
  const options = {
    quality: 0.8,
    maxWidth: 1920,
    maxHeight: 1080,
    format: 'image/pixu' as const, // Using PIX format for best compression
    stripMetadata: true,
  };

  const handleCompress = (result: CompressionResult) => {
    console.log('Compression completed:', result);
  };

  const handleError = (error: Error) => {

Com formato PIXU (melhor compressão)

import React from 'react';
import PixuCompressor from 'pixu/components/react/PixuCompressor';
import 'pixu/components/react/PixuCompressor.css';
import type { CompressionResult } from '@pantanal/pixu';

function App() {
  const handleCompress = (result: CompressionResult) => {
    console.log('PIX compression completed:', result);
    console.log('Size reduction:', (result.compressionRatio * 100).toFixed(1) + '%');
  };

  return (
    <PixuCompressor
      options={{ quality: 0.8, format: 'image/pixu' }}
      onCompress={handleCompress}
    />
  );
}

export default App;

Com preset

import React from 'react';
import PixuCompressor from 'pixu/components/react/PixuCompressor';
import 'pixu/components/react/PixuCompressor.css';
import type { CompressionResult } from '@pantanal/pixu';

function App() {
  const handleCompress = (result: CompressionResult) => {
    console.log('Web preset result:', result);
  };

  return (
    <PixuCompressor
      options={{ preset: 'web' }}
      onCompress={handleCompress}
    />
  );
}

export default App;

Com filtros

import React from 'react';
import PixuCompressor from 'pixu/components/react/PixuCompressor';
import 'pixu/components/react/PixuCompressor.css';
import type { CompressionResult } from '@pantanal/pixu';

function App() {
  const handleCompress = (result: CompressionResult) => {
    console.log('Filtered result:', result);
  };

  return (
    <PixuCompressor
      options={{
        quality: 0.8,
        filters: ['grayscale'],
      }}
      onCompress={handleCompress}
    />
