This project is under Alpha version.

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

Features

  • Camera autodetection,
  • Take a picture/movie capture,
  • Take a preview,
  • Retrieve camera list,
  • Select camera,
  • Take a liveview from camera and get binary or base64 of each frame, or write it to file,
  • Display info about your camera (summary, about, manual).

Prerequisite

  • Node.js: any version supported by nodejs/nan
  • NPM: ~7.10.0
  • Nan: ~2.8.0
  • 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

Note: This package cannot be used in front-end context (like webpack, browserify, etc...). You have to develop your own web server and expose your API.

Installation

After installing the dependencies, just install using:

npm install @tsed/gphoto2-core

Usage

Here an example with TypeScript (works also with pure javascript in Node.js):

import Path from "path";
import {CameraList, run} from "@tsed/gphoto2-driver";

run(
  () => {
    const cameraList = new CameraList().load();

    if (cameraList.size) {
      const camera = cameraList.getCamera(0);
      const cameraFile = camera.captureImage();

      cameraFile.save(path.join(__dirname, "capture.jpeg"));
    }
  },
  {logLevel: "debug"}
);

CameraFile

A lot of different API's of this library returns a CameraFile object.

This object does not contain the image, it is just a pointer to the file in camera's RAM.

You have several options to get your image:

  1. Use .save(filename) of .saveAsync(filename) methods, that will save the image to your filesystem.
  2. Use .getDataAndSizeAsync('binary' | 'base64') method, which returns following object:
{
  data: data, // Buffer for binary format and string for base64.
  size: size
}

Examples

Some examples are available in the packages/examples/src directory, when you have cloned or downloaded the complete project from github.

Checkout this project then run yarn run start:camera.
