All files in the project carrying such // notice may not be copied, modified, or distributed except // according to those terms. //! All the formats supported by Vulkan. //! //! A format is mostly used to describe the texel data of an image. However, formats also show up in //! a few other places, most notably to describe the format of vertex buffers. //! //! # Format support //! //! Not all formats are supported by every device. Those that devices do support may only be //! supported for certain use cases. It is an error to use a format where it is not supported, but //! you can query a device beforehand for its support by calling `format_properties` on the physical //! device. You can use this to select a usable format from one or more suitable alternatives. //! Some formats are required to be always supported for a particular usage. These are listed in the //! [tables in the Vulkan specification](https://registry.khronos.org/vulkan/specs/1.3-extensions/html/chap43.html#features-required-format-support). //! //! # Special format types //! //! ## Depth/stencil formats //! //! Depth/stencil formats can be identified by the `D` and `S` components in their names. They are //! used primarily as the format for framebuffer attachments, for the purposes of depth and stencil //! testing. //! //! Some formats have only a depth or stencil component, while others combine both. The two //! components are represented as separate *aspects*, which means that they can be accessed //! individually as separate images. These pseudo-images have the same resolution, but different //! bit depth and numeric representation. //! //! Depth/stencil formats deviate from the others in a few more ways. Their data representation is //! considered opaque, meaning that they do not have a fixed layout in memory nor a fixed size per //! texel. They also have special limitations in several operations such as copying; a depth/stencil //! format is not compatible with any other format, only with itself. //! //! ## Block-compressed formats //! //! A block-compressed format uses compression to encode a larger block of texels into a smaller //! number of bytes. Individual texels are no longer represented in memory, only the block as a //! whole. An image must consist of a whole number of blocks, so the dimensions of an image must be //! a whole multiple of the block dimensions. Vulkan supports several different compression schemes, //! represented in Vulkano by the `CompressionType` enum. //! //! Overall, block-compressed formats do not behave significantly differently from regular formats. //! They are mostly restricted in terms of compatibility. Because of the compression, the notion of //! bits per component does not apply, so the `components` method will only return whether a //! component is present or not. //! //! ## YCbCr formats //! //! YCbCr, also known as YUV, is an alternative image representation with three components: //! Y for luminance or *luma* (overall brightness) and two color or *chroma* components Cb and Cr //! encoding the blueness and redness respectively. YCbCr formats are primarily used in video //! applications. In Vulkan, the formats used to encode YCbCr data use the green channel to //! represent the luma component, while the blue and red components hold the chroma. //! //! To use most YCbCr formats in an [image view](crate::image::view), a //! [sampler YCbCr conversion](crate::sampler::ycbcr) object must be created, and attached to both //! the image view and the sampler. To query whether a format requires the conversion, you can call //! `ycbcr_chroma_sampling` on a format. As a rule, any format with `444`, `422`, `420`, //! `3PACK` or `4PACK` in the name requires it. //! //! Many YCbCr formats make use of **chroma subsampling**. This is a technique whereby the two //! chroma components are encoded using a lower resolution than the luma component. The human eye is //! less sensitive to color detail than to detail in brightness, so this allows more detail to be //! encoded in less data. Chroma subsampling is indicated with one of three numbered suffixes in a //! format name: //! - `444` indicates a YCbCr format without chroma subsampling. All components have the same //! resolution. //! - `422` indicates horizontal chroma subsampling. The horizontal resolution of the chroma //! components is halved, so a single value is shared within a 2x1 block of texels. //! - `420` indicates horizontal and vertical chroma subsampling. Both dimensions of the chroma //! components are halved, so a single value is shared within a 2x2 block of texels. //! //! Most YCbCr formats, including all of the `444` and `420` formats, are **multi-planar**. Instead //! of storing the components of a single texel together in memory, the components are separated //! into *planes*, which act like independent images. In 3-plane formats, the planes hold the Y, //! Cb and Cr components respectively, while in 2-plane formats, Cb and Cr are combined into a //! two-component plane. Where chroma subsampling is applied, plane 0 has the full resolution, while //! planes 1 and 2 have reduced resolution. Effectively, they are standalone images with half the //! resolution of the original. //! //! The texels of multi-planar images cannot be accessed individually, for example to copy or blit, //! since the components of each texel are split across the planes. Instead, you must access each //! plane as an individual *aspect* of the image. A single-plane aspect of a multi-planar image //! behaves as a regular image, and even has its own format, which can be queried with the `plane` //! method on a format. use crate::{ device::physical::PhysicalDevice, image::ImageAspects, macros::vulkan_bitflags, shader::spirv::ImageFormat, DeviceSize, }; // Generated by build.rs include!(concat!(env!("OUT_DIR"), "/formats.rs")); impl Format { /// Retrieves the properties of a format when used by a certain device. #[deprecated( since = "0.28.0", note = "Use PhysicalDevice::format_properties instead" )] #[inline] pub fn properties(self, physical_device: PhysicalDevice) -> FormatProperties { physical_device.format_properties(self).unwrap() } /// Returns whether the format can be used with a storage image, without specifying /// the format in the shader, if the /// [`shader_storage_image_read_without_format`](crate::device::Features::shader_storage_image_read_without_format) /// and/or /// [`shader_storage_image_write_without_format`](crate::device::Features::shader_storage_image_write_without_format) /// features are enabled on the device. #[inline] pub fn shader_storage_image_without_format(self) -> bool { matches!( self, Format::R8G8B8A8_UNORM | Format::R8G8B8A8_SNORM | Format::R8G8B8A8_UINT | Format::R8G8B8A8_SINT | Format::R32_UINT | Format::R32_SINT | Format::R32_SFLOAT | Format::R32G32_UINT | Format::R32G32_SINT | Format::R32G32_SFLOAT | Format::R32G32B32A32_UINT | Format::R32G32B32A32_SINT | Format::R32G32B32A32_SFLOAT | Format::R16G16B16A16_UINT | Format::R16G16B16A16_SINT | Format::R16G16B16A16_SFLOAT | Format::R16G16_SFLOAT | Format::B10G11R11_UFLOAT_PACK32 | Format::R16_SFLOAT | Format::R16G16B16A16_UNORM | Format::A2B10G10R10_UNORM_PACK32 | Format::R16G16_UNORM | Format::R8G8_UNORM | Format::R16_UNORM | Format::R8_UNORM | Format::R16G16B16A16_SNORM | Format::R16G16_SNORM | Format::R8G8_SNORM | Format::R16_SNORM | Format::R8_SNORM | Format::R16G16_SINT | Format::R8G8_SINT | Format::R16_SINT | Format::R8_SINT | Format::A2B10G10R10_UINT_PACK32 | Format::R16G16_UINT | Format::R8G8_UINT | Format::R16_UINT | Format::R8_UINT ) } } impl From for ash::vk::Format { #[inline] fn from(val: Format) -> Self { ash::vk::Format::from_raw(val as i32) } } // https://registry.khronos.org/vulkan/specs/1.3-extensions/html/chap46.html#spirvenv-image-formats impl From for Option { #[inline] fn from(val: ImageFormat) -> Self { match val { ImageFormat::Unknown => None, ImageFormat::Rgba32f => Some(Format::R32G32B32A32_SFLOAT), ImageFormat::Rgba16f => Some(Format::R16G16B16A16_SFLOAT), ImageFormat::R32f => Some(Format::R32_SFLOAT), ImageFormat::Rgba8 => Some(Format::R8G8B8A8_UNORM), ImageFormat::Rgba8Snorm => Some(Format::R8G8B8A8_SNORM), ImageFormat::Rg32f => Some(Format::R32G32_SFLOAT), ImageFormat::Rg16f => Some(Format::R16G16_SFLOAT), ImageFormat::R11fG11fB10f => Some(Format::B10G11R11_UFLOAT_PACK32), ImageFormat::R16f => Some(Format::R16_SFLOAT), ImageFormat::Rgba16 => Some(Format::R16G16B16A16_UNORM), ImageFormat::Rgb10A2 => Some(Format::A2B10G10R10_UNORM_PACK32), ImageFormat::Rg16 => Some(Format::R16G16_UNORM), ImageFormat::Rg8 => Some(Format::R8G8_UNORM), ImageFormat::R16 => Some(Format::R16_UNORM), ImageFormat::R8 => Some(Format::R8_UNORM), ImageFormat::Rgba16Snorm => Some(Format::R16G16B16A16_SNORM), ImageFormat::Rg16Snorm => Some(Format::R16G16_SNORM), ImageFormat::Rg8Snorm => Some(Format::R8G8_SNORM), ImageFormat::R16Snorm => Some(Format::R16_SNORM), ImageFormat::R8Snorm => Some(Format::R8_SNORM), ImageFormat::Rgba32i => Some(Format::R32G32B32A32_SINT), ImageFormat::Rgba16i => Some(Format::R16G16B16A16_SINT), ImageFormat::Rgba8i => Some(Format::R8G8B8A8_SINT), ImageFormat::R32i => Some(Format::R32_SINT), ImageFormat::Rg32i => Some(Format::R32G32_SINT), ImageFormat::Rg16i => Some(Format::R16G16_SINT), ImageFormat::Rg8i => Some(Format::R8G8_SINT), ImageFormat::R16i => Some(Format::R16_SINT), ImageFormat::R8i => Some(Format::R8_SINT), ImageFormat::Rgba32ui => Some(Format::R32G32B32A32_UINT), ImageFormat::Rgba16ui => Some(Format::R16G16B16A16_UINT), ImageFormat::Rgba8ui => Some(Format::R8G8B8A8_UINT), ImageFormat::R32ui => Some(Format::R32_UINT), ImageFormat::Rgb10a2ui => Some(Format::A2B10G10R10_UINT_PACK32), ImageFormat::Rg32ui => Some(Format::R32G32_UINT), ImageFormat::Rg16ui => Some(Format::R16G16_UINT), ImageFormat::Rg8ui => Some(Format::R8G8_UINT), ImageFormat::R16ui => Some(Format::R16_UINT), ImageFormat::R8ui => Some(Format::R8_UINT), ImageFormat::R64ui => Some(Format::R64_UINT), ImageFormat::R64i => Some(Format::R64_SINT), } } } /// The block compression scheme used in a format. #[derive(Clone, Copy, Debug, PartialEq, Eq, Hash)] #[allow(non_camel_case_types)] pub enum CompressionType { /// Adaptive Scalable Texture Compression, low dynamic range.
