In general, assume linear color space.
| Suffix | Description |
|---|
Unorm | Float values in range [0, 1] are converted to the [0, 255] unsigned 8-bit range. |
Snorm | Float values in range [0, 1] are converted to the [-127, 127] signed 8-bit range. |
Float | Each channel is a float, usually 16-bit or 32-bit |
Uint | Each channel is assumed already an integer in the unsigned range [0, 255] |
Sint | Each channel is assumed already an integer in the signed range [-127, 127] |
Srgb | Assumes the channel color in range [0, 255] is in Srgb-color space |
| Prefix | Description |

R16 | Red channel with 16-bits per channel. |
R32 | Red channel with 32-bits per channel. |
Rg8 | Red and green channel with 8-bits per channel. |
Rg16 | Red and green channel with 16-bits per channel. |
Rg32 | Red and green channel with 32-bits per channel. |
Rgba8 | Red, green, blue, and alpha channels with 8-bits per channel. |
Rgba16 | Red, green, blue, and alpha channels with 16-bits per channel. |
Rgba32 | Red, green, blue, and alpha channels with 32-bits per channel. |
Bgra8 | Blue, green, red, alpha channels (in that order) with 8-bits per channel. |
Rgb10a2 | Red, green, blue channels with 10-bits per channel [0, 1023], plus a 2-bit [0, 3] alpha channel. |
Rg11b10 | Red and green channel with 11-bits per channel, plus a blue channel with 10-bits. Typically these channels are floats. |
