The BrightSign implementation of the Chromium engine includes several platform-specific extensions. Extensions for <video> elements are covered on the HTML Video 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.
