name: image-crop
description: Crop images and get image metadata using sharp library. Use when user asks to crop, trim, cut an image, or get image dimensions/info. Supports JPEG, PNG, WebP.
---
# Image Crop Skill
Image manipulation using the sharp library.
## Scripts
### Get Image Info
```bash
node scripts/image-info.js <image-path>
```
Returns dimensions, format, DPI, alpha channel info.
### Crop Image
```bash
node scripts/crop-image.js <input> <output> <left> <top> <width> <height>
```
Parameters:
- `left`, `top` - offset from top-left corner (pixels)
- `width`, `height` - size of crop area (pixels)
## Workflow Example
1. Get dimensions first:
```bash
node scripts/image-info.js photo.jpg
# Size: 1376x768
```
2. Calculate crop (e.g., remove 95px from top and bottom):
```bash
# new_height = 768 - 95 - 95 = 578
node scripts/crop-image.js photo.jpg photo-cropped.jpg 0 95 1376 578
```
## Requirements
Node.js with sharp (`npm install sharp`)
