CamSnap (Screen & Camera Capture)

Capture screenshots of the screen or specific windows, and take snapshots from a connected camera/webcam.

Usage

• "Take a screenshot of my screen"
• "Capture the current Chrome window"
• "Take a screenshot of the region around the top-left corner"
• "Snap a photo from my webcam"
• "List available displays"
• "Screenshot my second monitor"

How it works

Uses platform-native screen capture tools and optional camera utilities to produce image files.

macOS

• Screenshots: Uses the built-in screencapture command.
  • Full screen: screencapture output.png
  • Specific window (interactive): screencapture -w output.png
  • Region: screencapture -R x,y,w,h output.png
  • Specific display: screencapture -D <display_id> output.png
• Camera: Uses imagesnap to capture a frame from the default or a specified camera device.
  • Snap: imagesnap output.jpg
  • List devices: imagesnap -l

Linux

• Screenshots: Uses scrot or ImageMagick import.
  • Full screen: scrot output.png
  • Focused window: scrot -u output.png
  • Region: import -window root -crop WxH+X+Y output.png
  • With selection: scrot -s output.png
• Camera: Uses ffmpeg to grab a single frame from a video device.
  • Snap: ffmpeg -f v4l2 -i /dev/video0 -frames:v 1 output.jpg
  • List devices: v4l2-ctl --list-devices

All captured images are saved to the current working directory or a specified path.

Setup
