Color Profile
Color Profile (ICC Profile)
A color profile defines how numerical color values map to actual colors on a specific device. ICC profiles ensure colors look consistent across different monitors, printers, and cameras by providing a standardized color interpretation.
तकनीकी विवरण
ICC profiles contain lookup tables and parametric curves that map device-dependent color values to the Profile Connection Space (PCS), typically CIELAB or CIEXYZ. Profiles can be matrix-based (for monitors) or table-based (for printers).
उदाहरण
```javascript
// Read EXIF data from image file
const buffer = await file.arrayBuffer();
const view = new DataView(buffer);
// Check JPEG SOI marker
if (view.getUint16(0) === 0xFFD8) {
// EXIF starts at APP1 marker (0xFFE1)
// Fields: camera model, aperture, ISO, GPS coords
}
// Strip EXIF: re-draw on canvas → export (removes metadata)
```
