# MTLPixelFormat.bgr10_xr_srgb A 32-bit extended-range pixel format with sRGB conversion and three fixed-point components of 10-bit blue, 10-bit green, and 10-bit red. ``` case bgr10_xr_srgb ``` ## Discussion Pixel components are stored in blue, green, and red order, from least significant bit to most significant bit. Bits 30 and 31 are padding, and their value is `0`. ![Bit layout diagram showing the pixel data storage arrangement of the bgr10_xr_srgb pixel format. The blue component is stored in bits 0 to 9, the green component is stored in bits 10 to 19, the red component is stored in bits 20 to 29, and bits 30 to 31 are used as padding.](images/com.apple.metal/bgr10-xr-layout-1@2x.png) The blue, green, and red components are gamma encoded, and their values range from `-0.5271` to `1.66894`, before gamma expansion. In order to determine a component’s value as a shader float: - When reading a pixel, first apply the linear encoding `(xr10_value - 384) / 510.0f` and then the sRGB transform. - When writing a pixel, first apply the sRGB transform and then the linear encoding `shader_float = (xr10_value - 384) / 510.0f`. To display wide color values on devices with wide color displays, you set this pixel format on the property of an or the property of a . Also provide an extended sRGB color space. > Note: > Only devices with a wide color display can display color values outside the `[0.0, 1.0]` range; all other devices clamp color values to the `[0.0, 1.0]` range. --- Copyright © 2026 Apple Inc.
