## Image Resizer API - Batch Image Processing & Smart Cropping

**Professional Image Resizer API** for automated batch image processing. Resize images to any dimensions with smart cropping, format conversion, and quality optimization. Perfect for web optimization, e-commerce, social media, and responsive design.

### Features

✅ **Multiple Image Formats**: Supports JPEG, PNG, WebP, TIFF\
✅ **Batch Processing**: Handle multiple images simultaneously\
✅ **Smart Cropping**: Intelligent face/subject detection using entropy analysis\
✅ **Flexible Resizing**: Multiple fit modes (cover, contain, fill, inside, outside)\
✅ **Format Conversion**: Convert between different image formats\
✅ **Quality Control**: Customizable compression settings\
✅ **Multiple Input Sources**: URLs, Base64, or Key-Value Store

### Pricing Model

This Actor uses **Pay-per-Event** pricing:

| Event | Cost | Description |
|-------|------|-------------|
| ACTOR\_START | $0.01 | Charged once when Actor starts |
| ACTOR\_PROCESSING | $0.005 | Charged for each image processed |
| ACTOR\_COMPLETE | $0.005 | Charged once when Actor completes |

**Example Cost Calculation:**

- Processing 10 images = $0.01 (start) + $0.05 (10 × processing) + $0.005 (complete) = **$0.065**

### Input Configuration

#### Required Fields

- **images**: Array of image objects with one of:
  - `url`: Direct image URL
  - `base64`: Base64 encoded image data
  - `keyValueStoreKey`: Key from Apify Key-Value Store

#### Optional Fields

- **width**: Target width in pixels (1-10000)
- **height**: Target height in pixels (1-10000)
- **fit**: Resize mode
  - `cover`: Crop to fill dimensions (default)
  - `contain`: Fit within dimensions with letterboxing
  - `fill`: Stretch to exact dimensions
  - `inside`: Resize to fit inside dimensions
  - `outside`: Resize to fit outside dimensions
- **position**: Crop position for 'cover' mode
  - `smart`: Intelligent face/subject detection
  - `center`, `top`, `bottom`, `left`, `right`
- **format**: Output format (`jpeg`, `png`, `webp`, `tiff`)
- **quality**: 1-100 (default: 80)
- **backgroundColor**: RGBA color for letterboxing
- **outputFolder**: Folder name in Key-Value Store (default: "resized-images")

### Example Input

```json
{
  "images": [
    {
      "url": "https://example.com/image1.jpg"
    },
    {
      "url": "https://example.com/image2.png",
      "filename": "custom-name"
    }
  ],
  "width": 800,
  "height": 600,
  "fit": "cover",
  "position": "smart",
  "format": "webp",
  "quality": 85
}
```

### Output

Results are saved to the Dataset with:

```json
{
  "summary": {
    "totalImages": 2,
    "processedSuccessfully": 2,
    "errors": 0,
    "successRate": "100.00%"
  },
  "results": [
    {
      "success": true,
      "originalFilename": "image1.jpg",
      "outputFilename": "resized-images/image1_800x600.webp",
      "publicUrl": "https://api.apify.com/v2/key-value-stores/.../records/...",
      "originalSize": {
        "width": 1920,
        "height": 1080,
        "format": "jpeg",
        "bytes": 245678
      },
      "outputSize": {
        "width": 800,
        "height": 600,
        "format": "webp",
        "bytes": 45230
      },
      "compressionRatio": "81.58%"
    }
  ]
}
```

### Use Cases

#### 🌐 Web Development

Optimize images for responsive websites with multiple breakpoints

#### 🛒 E-commerce

Generate product thumbnails and multiple size variants

#### 📱 Social Media

Resize images for different platform requirements (Instagram, Facebook, Twitter)

#### 📰 Content Management

Batch process uploaded images for blogs and news sites

#### 📲 Mobile Apps

Create app icons and assets in various sizes

### API Integration

```javascript
import { ApifyClient } from 'apify-client';

const client = new ApifyClient({ token: 'YOUR_API_TOKEN' });

const run = await client.actor('YOUR_USERNAME/image-resize-api').call({
  images: [
    { url: 'https://example.com/image.jpg' }
  ],
  width: 800,
  height: 600,
  fit: 'cover',
  format: 'webp',
  quality: 85
});

const dataset = await client.dataset(run.defaultDatasetId).listItems();
console.log(dataset.items[0]);
```

### Smart Cropping

When using `"position": "smart"`, the Actor uses advanced algorithms to detect:

- 👤 Faces
- 🎯 Areas of interest (high contrast/detail)
- 📐 Composition balance

This ensures important subjects stay in frame when cropping.

### Performance Tips

1. **Batch Processing**: Group multiple images in one run to minimize startup costs
2. **WebP Format**: Best compression ratio for web use
3. **Quality Setting**: 80-85 is optimal for most use cases
4. **Smart Cropping**: Only use when needed (adds processing time)

# Actor input Schema

## `images` (type: `array`):

Array of images to resize. Each image can be provided as URL, base64, or Key-Value Store key.

## `width` (type: `integer`):

Target width in pixels. Leave empty for auto-scaling based on height.

## `height` (type: `integer`):

Target height in pixels. Leave empty for auto-scaling based on width.

## `fit` (type: `string`):

How the image should be resized to fit the dimensions.

## `position` (type: `string`):

Position for cropping (when fit is 'cover'). Use 'smart' for intelligent face/subject detection.

## `format` (type: `string`):

Output image format. Leave empty to keep original format.

## `quality` (type: `integer`):

Output quality (1-100). Higher values mean better quality but larger file size.

## `outputFolder` (type: `string`):

Folder name in Key-Value Store for output images
