What is Aspect Ratio?

Aspect Ratio — Image Width-to-Height Proportions

Aspect ratio is the proportional relationship between an image's width and height, expressed as two numbers separated by a colon. Common ratios include 16:9 (widescreen), 4:3 (classic), and 1:1 (square).

Detail Teknis

Aspect ratio is calculated by dividing width and height by their greatest common divisor. Changing an image's aspect ratio without cropping requires adding padding or distorting the content.

Contoh

```javascript
// Crop image to specific region
const canvas = document.createElement('canvas');
canvas.width = cropWidth;
canvas.height = cropHeight;
const ctx = canvas.getContext('2d');
ctx.drawImage(
  img,
  cropX, cropY, cropWidth, cropHeight,  // source rect
  0, 0, cropWidth, cropHeight            // dest rect
);
```
