# keepIccProfile()

> Enable ICC color profile preservation using Sharp

Configures OpenComic AI to preserve ICC color profiles in output images by integrating with the Sharp image processing library. This ensures color accuracy when upscaling images with embedded color profiles.

## Syntax

```typescript theme={null}
OpenComicAI.keepIccProfile(sharp: any, pipelineColourspace?: string): void
```

## Parameters

<ParamField path="sharp" type="any" required>
  The Sharp instance to use for ICC profile preservation. Pass the Sharp library object.
</ParamField>

<ParamField path="pipelineColourspace" type="string" default="rgb16">
  The color space to use in the Sharp processing pipeline. Common values: `'rgb16'`, `'srgb'`, `'rgb'`.
</ParamField>

## Returns

`void` - This method does not return a value.

## Behavior

* Integrates Sharp for post-processing upscaled images
* Preserves embedded ICC color profiles from source images
* Applies the profile to output images automatically
* Uses the specified color space for internal processing

## Example

```typescript theme={null}
import OpenComicAI from '@opencomic/ai-bin';
import sharp from 'sharp';

// Enable ICC profile preservation
OpenComicAI.keepIccProfile(sharp);

// Upscale an image with color profile preservation
await OpenComicAI.upscale({
  input: 'photo.jpg',
  output: 'upscaled-photo.jpg'
});
```

## Custom color space

```typescript theme={null}
import sharp from 'sharp';

// Use sRGB color space instead of rgb16
OpenComicAI.keepIccProfile(sharp, 'srgb');
```

## Why preserve ICC profiles?

ICC profiles ensure consistent color reproduction across different devices and applications. Without preservation:

* Colors may appear differently than intended
* Professional photography workflows may break
* Color-calibrated images lose their calibration

With ICC profile preservation:

* Original color intent is maintained
* Professional color accuracy is preserved
* Images display consistently across platforms

## Installation

This feature requires the Sharp library:

```bash theme={null}
npm install sharp
```

## Color space options

* `'rgb16'` (default) - 16-bit RGB color space, highest quality
* `'srgb'` - Standard RGB color space
* `'rgb'` - 8-bit RGB color space

Choose `'rgb16'` for maximum color fidelity, or `'srgb'` for smaller file sizes.
