Capturing screenshots in a Unity web application involves capturing the current state of the application's viewport and saving it as an image file. This can be useful for various purposes, such as sharing gameplay moments, creating documentation, or debugging. Below is a description of how to achieve screenshot capture in a Unity web application using blippar sdk:

## Screenshot Preview <a href="#h_screenshotpreview" id="h_screenshotpreview"></a>

A screenshot preview in a web application involves capturing a visual representation of the current state of the application's viewport and displaying it as a preview within the application's user interface. This feature allows users to quickly see a snapshot of the scene they are interacting. The UI provides two options in preview window, delete and download

* Delete Screenshot
* Download Screebshot

## Take screenshot programmatically <a href="#h_screenshotpreview" id="h_screenshotpreview"></a>

Taking screenshots programmatically in a Unity application allows you to capture the current state of the game or application.

* Uncheck the "Enable Photo UI" from inspector window.
* Write a script to cature screenshot and call a method "WEBARSDK.TakeScreenshot(returnBuffer)"
* "returnBuffer" is a boolean value if returnBuffer->false a preview UI with download button is displayed on the screen.
* and if "returnBuffer" is true the "WEBARSDK.TakeScreenshot" method converts the screenshot image data in binary format and to access this data user needs to call a method "WEBARSDK.GetScreenshotTexture" after some delay.
* "WEBARSDK.GetScreenshotTexture" will return a image data in base64 string format, using this string user can convert or use it anywhere according to the use case.
