The BrightSign implementation of the Chromium engine includes several platform-specific extensions. Extensions for \<video> elements are covered on the [HTML Video](docId\:e6uJleH69Q0JmMv8kyTrp) page.

## GPU Rasterization

GPU rasterization is enabled by default in firmware versions 6.2.x and later. 

## Optimized Image Rendering

The `image-rendering` CSS property can be assigned the `optimizeSpeedBS` value. Using this value ensures that Chromium uses lower-quality but faster bilinear filtering when scaling images to 50% or less. We recommend using this value with pages that scale a lot of images at runtime.

## More Information

This [GitHub repo](https://github.com/brightsign/extension-template) provides a guide to creating, debugging, and deploying extensions.
