# Screen Capture (macOS)

## Quick Start

```bash
screencapture -x ~/screenshot.png          # Full screen (silent)

screencapture -c                            # Capture to clipboard
```

## Commands

```bash
screencapture -x ~/screenshot.png                    # Silent full screen
screencapture ~/screenshot.png                       # Full screen with shutter sound
screencapture -T 3 ~/screenshot.png                  # 3-second delay
```

### Region / Window

```bash
screencapture -i ~/region.png                        # Interactive: drag to select region
screencapture -iW ~/window.png                       # Interactive: click to select window
screencapture -R 0,0,1280,720 ~/region.png           # Specific coordinates (x,y,w,h)
```

### Specific Application Window

```bash
# Capture Chrome window by window ID
screencapture -l$(osascript -e 'tell app "Google Chrome" to id of window 1') ~/chrome.png

# Capture any app window
screencapture -l$(osascript -e 'tell app "Safari" to id of window 1') ~/safari.png

# Capture frontmost window
screencapture -l$(osascript -e 'tell app "System Events" to id of first window of (first process whose frontmost is true)') ~/front.png
```

### Clipboard

```bash
screencapture -c                                     # Full screen to clipboard
screencapture -ic                                    # Region select to clipboard
```

### Multiple Displays

```bash
screencapture ~/screen1.png ~/screen2.png            # One file per display
screencapture -D 1 ~/main.png                        # Main display only
screencapture -D 2 ~/secondary.png                   # Secondary display
```

### Video Recording

```bash
screencapture -v ~/recording.mov                     # Record screen video
screencapture -V 10 ~/recording.mov                  # Record 10 seconds
```

## Webcam Capture (requires imagesnap)

```bash
# Install
brew install imagesnap

# Capture
imagesnap ~/camera.png                               # Take photo
imagesnap -w 2 ~/camera.png                          # 2-second warmup (better quality)
imagesnap -d "FaceTime HD Camera" ~/camera.png       # Specific camera

# List cameras
imagesnap -l
```

## Output Formats
