atom-screenshot
Atom editor plugin for creating code screenshots
With this package, you can take a screenshot of your code as it is shown in Atom. With syntax highlighting and line numbers, but without any menus or toolbars.
It captures every line from first to last into a single image by scrolling through the file.
Usage
You can invoke the package through the "screenshot:take" command, through the "Packages" menu in the menu bar, or via the context menu. Note that a text editor needs to be active so that this package knows which code to capture.
Example
This is the output image:
