# Addon

## What is the difference between Camera.play and Camera.showVideo?

> **The Camera Add-on has been removed since Dynamic Web TWAIN [18.1](_articles/info/schedule/deprecated.md#181).** An alternative replacement for this module is [Mobile Document Scanner](https://www.dynamsoft.com/use-cases/mobile-document-scanner/).

`Camera.showVideo` is a built-in feature to handle camera capturing, prospective adjusting, etc. It supports two available modes: document and picture.

`Camera.play` is a more specific API for starting streaming video from the current camera.

Note that these two APIs cannot be mixed with each other.

Please check [here](/_articles/info/api/Addon_Camera.md){:target="_blank"} for more information on the Camera APIs.

# Capture/Image Source

## Can I import existing images or PDF documents using the Dynamic Web TWAIN SDK?

Yes, Dynamic Web TWAIN supports loading PNG, JPG, BMP, image-only PDF, and TIFF files. But if you need to support text-based PDF files, you also require the <a href="https://www.dynamsoft.com/web-twain/pdf-to-image-javascript/" target="_blank">PDF Rasterizer Addon</a>. See more [here](/_articles/indepth/features/pdf.md#input){:target="_blank"}.
