Node.js wrapper for libgphoto2
npm install 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 (npx coffee examples/server.coffee) which runs on http://localhost:1337 and allows to change camera settings and to take pictures.
* Node.js: versions 10 (LTS), 12 (LTS), 13 (current)
* libgphoto2: ~2.5.x - via brew install libgphoto2, apt-get install libgphoto2-dev or download and build from http://www.gphoto.org/proj/libgphoto2/
* pkg-config | dpkg (used for dependency checking)
* clang compiler
* async
* coffee-script
* mocha
* pre-commit
* should
* sinon
* superagent
* express
* jade
* underscore
After installing the dependencies, just install using:
``
npm install gphoto2
If it fails, please thoroughly check the output - link errors usually indicate missing dependencies.
Also, the script tries to detect wether libgphoto2 is correctly installed - if this check fails although you properly installed it, please report :)
This example only shows how to achieve certain tasks, it's not meant to be executed without any asynchronous control flow logic.
`javascript
var fs = require('fs');
var gphoto2 = require('gphoto2');
var GPhoto = new gphoto2.GPhoto2();
// Negative value or undefined will disable logging, levels 0-4 enable it.
GPhoto.setLogLevel(1);
GPhoto.on('log', function (level, domain, message) {
console.log(domain, message);
});
// List cameras / assign list item to variable to use below options
GPhoto.list(function (list) {
if (list.length === 0) return;
var camera = list[0];
console.log('Found', camera.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.writeFileSync(__dirname + '/picture.jpg', data);
});
// Take picture and keep image on camera
camera.takePicture({
download: true,
keep: true
}, function (er, data) {
fs.writeFileSync(__dirname + '/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({
targetPath: '/tmp/foo.XXXXXX'
}, function (er, tmpname) {
fs.renameSync(tmpname, __dirname + '/picture.jpg');
});
// Download a picture from camera
camera.downloadPicture({
cameraPath: '/store_00020001/DCIM/100CANON/IMG_1231.JPG',
targetPath: '/tmp/foo.XXXXXX'
}, function (er, tmpname) {
fs.renameSync(tmpname, __dirname + '/picture.jpg');
});
// Get preview picture (from AF Sensor, fails silently if unsupported)
camera.takePicture({
preview: true,
targetPath: '/tmp/foo.XXXXXX'
}, function (er, tmpname) {
fs.renameSync(tmpname, __dirname + '/picture.jpg');
});
});
