Basic Usage

imagesnap

This will capture a photo with the default settings and save it to the current directory as a JPEG image.

Adjusting Settings

You can adjust various settings of the camera by using command-line arguments when running Imagesnap. Here are some examples:

• -w or --width: Sets the width of the photo in pixels.
• -h or --height: Sets the height of the photo in pixels.
• -t or --timeout: Sets the number of seconds to wait before capturing the photo.
• -q or --quality: Sets the JPEG compression level (0-100).
• -v or --verbose: Prints information about the capture process to the Terminal.

For example, to capture a 640x480 photo with a 3-second delay and verbose output, you could run:

imagesnap -w 640 -h 480 -t 3 -v

Saving to a Specific Location

By default, Imagesnap saves the captured photo to the current working directory. However, you can specify a different location by providing a file path as an argument.

For example, to save a photo to your desktop, you would run:

imagesnap ~/Desktop/photo.jpg
