[−][src]Module rendy_core::hal::image

Image related structures.

An image is a block of GPU memory representing a grid of texels.

Structs

Access	Bitflags to describe how memory in an image or buffer can be accessed.
Extent	Describes the size of an image, which may be up to three dimensional.
FormatProperties	Image format properties.
Lod	A wrapper for the LOD level of an image. Needed so that we can implement Eq and Hash for it.
Offset	An offset into an `Image` used for image-to-image copy operations. All offsets are in texels, and specifying offsets other than 0 for dimensions that do not exist is undefined behavior -- for example, specifying a `z` offset of `1` in a two-dimensional image.
PackedColor	A wrapper for an RGBA color with 8 bits per texel, encoded as a u32.
SamplerDesc	Specifies how to sample from an image. These are all the parameters available that alter how the GPU goes from a coordinate in an image to producing an actual value from the texture, including filtering/ scaling, wrap mode, etc.
Subresource	Selector of a concrete subresource in an image.
SubresourceFootprint	Footprint of a subresource in memory.
SubresourceLayers	A subset of resource layers contained within an image's level.
SubresourceRange	A subset of resources contained within an image.
Usage	TODO: Find out if TRANSIENT_ATTACHMENT + INPUT_ATTACHMENT are applicable on backends other than Vulkan. --AP Image usage flags
ViewCapabilities	Capabilities to create views into an image.

Anisotropic	Anisotropic filtering description for the sampler.
CreationError	Pure image object creation error.
CubeFace	The face of a cube image to do an operation on.
Filter	How to filter the image when sampling. They correspond to increasing levels of quality, but also cost.
Kind	Specifies the dimensionality of an image to be allocated, along with the number of mipmap layers and MSAA samples if applicable.
LayerError	An error associated with selected image layer.
Layout	Specifies options for how memory for an image is arranged. These are hints to the GPU driver and may or may not have actual performance effects, but describe constraints on how the data may be used that a program must obey. They do not specify how channel values or such are laid out in memory; the actual image data is considered opaque.
Tiling	Image tiling modes.
ViewError	Error creating an `ImageView`.
ViewKind	Specifies the kind/dimensionality of an image view.
WrapMode	Specifies how image coordinates outside the range `[0, 1]` are handled.

CUBE_FACES	A constant array of cube faces in the order they map to the hardware.
MAX_LEVEL	Maximum accessible mipmap level of an image.

Layer	Image layer.
Level	Image mipmap level.
NumSamples	Number of MSAA samples.
Size	Dimension size.
State	Image state, combining access methods and the image's layout.
TexelCoordinate	A texel coordinate in an image.
