In drawer: An Interactive HTML Image Editing Tool

drawer

{drawer} is an interactive image editing tool that can be added as part of the HTML in Shiny, R markdown or any type of HTML document. Often times, plots, photos are embedded in the web application/file. {drawer} can take screenshots of these image-like elements, or any part of the HTML document and send to an image editing space called "canvas" to allow users immediately edit the screenshot(s) within the same document. Users can quickly combine, compare different screenshots, upload their own images and maybe make a scientific figure.

{drawer} is built with 99% javascript + HTML + CSS, there is no need to have a Shiny server or any other types of server in the back-end. That's why you can use it in any HTML document. All you need is a modern web browser, like Chrome or Firefox (IE will not work).
Shiny and R markdown compatible.
Screenshot any element in the page and edit in canvas or download it png or jpg
Drag and upload your own images.

{drawer} is originally part of systemPipeShiny (SPS), the SPS Canvas functionality. However, one cannot use it outside SPS framework and installing the whole SPS framework is heavy. To benefit more people in their own apps/documents, we provide {drawer} as a separate package.
