Mipmap
Mipmap (Multum In Parvo)
A set of pre-computed, progressively smaller versions of a texture used to improve rendering speed and reduce aliasing.
Chi tiết kỹ thuật
In digital imaging, mipmap plays a critical role in how images are stored, processed, and displayed. Modern image pipelines handle set through standardized APIs (Canvas, WebGL, ImageBitmap) that operate directly on GPU memory for performance. Understanding mipmap is essential for optimizing web delivery, where image payload typically accounts for 40-60% of total page weight. Browser-based tools can manipulate set entirely client-side using the Canvas API without server round-trips.
Ví dụ
```javascript
// Mipmap: 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)
```
