Dithering (Image)
Image Dithering
A technique that simulates additional colors by arranging limited-palette pixels in patterns that blend visually.
Detalhe técnico
Dithering (Image) determines the level of detail an image can capture. In digital imaging, resolution is typically stated as width x height in pixels (e.g. 3840x2160 for 4K). For print, PPI (pixels per inch) maps these pixels to physical dimensions — 300 PPI is standard for professional printing while 72-96 PPI suffices for screen display. Increasing resolution beyond the original capture requires interpolation algorithms (bicubic, Lanczos) that estimate new pixel values, which adds softness rather than true detail.
Exemplo
```javascript
// Dithering (Image): processing with Canvas API
const canvas = document.createElement('canvas');
const ctx = canvas.getContext('2d');
ctx.drawImage(sourceImage, 0, 0);
const imageData = ctx.getImageData(0, 0, canvas.width, canvas.height);
// Process pixels in imageData.data (RGBA array)
```
