A Node.js wrapper for libgphoto2

Primary LanguageC++

node-gphoto2

A Node.js wrapper for libgphoto2. Useful for remote controlling of DSLRs and other digital cameras supported by gphoto2.

The included test application currently allows you to

  • receive a live preview of your camera (if supported). Tested with an EOS 550D on a 2010 iMac at ~17 fps using Chrome (Safari doesn't work and FF is slow as hell).
  • query a list of available configuration options
  • query the values of specific configuration options

The test suite can be run using npm test. There's also a small test application in test/test-server.coffee which runs on http://localhost:1337 and allows to change camera settings and to take pictures.

Usage

gphoto2 = require('gphoto2');
GPhoto = new gphoto2.GPhoto2();

// List cameras / assign list item to variable to use below options
GPhoto.list(function(list){console.log(list[0].model)});

// get configuration tree
camera.getConfig(function(er, settings){
  console.log(settings);
});

// Set configuration values
camera.setConfigValue('capturetarget', 1, function(er){
  //...
})

// Take picture with camera object obtained from list()
camera.takePicture({download:true}, function(er, data){
  fs.writeFile("picture.jpg", data);
});

// Take picture without downloading immediately
camera.takePicture({download:false}, function(er, path){
  console.log(path);
});

// Take picture and download it to filesystem
camera.takePicture({
    download:true,
    targetPath:'/tmp/foo.XXXXX'
  }, function(er, tmpname){
    fs.rename(tmpname, './picture.jpg');
});

// Download a picture from camera
camera.downloadPicture({
    cameraPath:'/store_00020001/DCIM/100CANON/IMG_1231.JPG',
    targetPath:'/tmp/foo.XXXXX'
  }, function(er, tmpname){
    fs.rename(tmpname, './picture.jpg');
});

// Get preview picture (from AF Sensor, fails silently if unsupported)
camera.getPreview(function(data){
  fs.writeFile("picture.jpg", data);
});
