screenshot-ftw v1.0.5

screenshot-ftw

An attempt to take a window screenshot across OSes.

Why? I couldn't find one that didn't have too many dependencies and most only take the full screen.

usage

npm install --save screenshot-ftw

import { screenshot } from 'screenshot-ftw';

...
const windows = await screenshot.getWindows();

await screenshot.captureWindowByTitle("foo.png", "some window title");
await screenshot.captureWindowById("foo.png", windows[0].id);
await screenshot.captureScreen("foo.png");

getWindows returns an array of {id: number, title: string} where id can be passed to captureWindowById. This is useful for capturing a window who's title changes (for example a browser). Set the browser's window title to a known name, call getWindows and find its id. Then pass that id for all screenshots.

Note: at the moment only .PNG format is supported

To Do:

Generate 16bit screenshots.

Notes:

Linux is problematic

At the moment it uses gnome-screencapture and only handle's full screen captures. It would be nice if it could check for various methods (imagemagick) etc... and also handle windows.
