Snap webcam photos from the command line.
like scrot, but for external use: taking webcam shots
Sometimes I like to take a quick picture of a whiteboard or some notes, but don't want to go find a phone and fiddle with getting images off of it.
With npm installed, run
$ npm install --global exrot
USAGE:
exrot [OPTIONS]... [FILE]
Where FILE is the target file for the screenshot.
If FILE is not specified, a date-stamped file will be dropped in the
current directory.
-h, --help display this help and exit
-d, --delay NUM wait NUM seconds before taking a shot
-x, --sfx play a camera shutter sound when finished
-i, --interactive bring up an interactive video; click to snap
var exrot = require('exrot')
var opts = {
width: 320,
height: 240,
sfx: true,
interactive: false
}
exrot(opts, function (err, data) {
if (err) throw err
process.stdout.write(data)
})
