LiteFX::Rendering::Backends::IDirectX12Image

`LiteFX::Rendering::Backends::IDirectX12Image`¶

Represents a DirectX 12 sampled image or the base interface for a texture.

Synopsis¶

Declared in <litefx/backends/dx12.hpp>

class [[dllimport, dllexport]] IDirectX12Image
    : public virtual IImage
    , public virtual IResource<ComPtr<ID3D12Resource>>

Base Classes¶

Name	Description
`IImage`	Describes a generic image.
`IResource<ComPtr<ID3D12Resource>>`	Provides access to a resource managed by the class.

Types¶

Name	Description
`PrepareMoveEventArgs`	Stores a reference to a barrier that can be used to synchronize accesses to the resource with a move operation.
`ResourceMovingEventArgs`	Stores the fence and the command queue to wait on for the fence before a moved resource can be used.

Type Aliases¶

Name
`_Esft_type`

Member Functions¶

Name	Description
`~IDirectX12Image` [destructor] [virtual]	Destructor
`alignedElementSize` [virtual]	Returns the actual size of the element in device memory.
`dimensions` [virtual]	Gets the images dimensionality.
`elementAlignment` [virtual]	Returns the alignment of a single element.
`elementSize` [virtual]	Returns the size of a single element within the buffer. If there is only one element, this is equal to `size`.
`elements` [virtual]	Gets the number of sub-resources inside the memory chunk.
`extent` [virtual]	Gets the extent of the image at a certain mip-map level.
`format` [virtual]	Gets the internal format of the image.
`handle` [virtual]	Returns the resource managed by the class.
`layers` [virtual]	Gets the number of layers (slices) of the image.
`levels` [virtual]	Gets the number of mip-map levels of the image.
`name` [virtual]	Returns the name of the resource.
`planes` [virtual]	Returns the number of planes of the image resource.
`resolveSubresource` [virtual]	Returns the `plane,` `layer` and `level` for the provided `subresource.`
`samples` [virtual]	Gets the number of samples of the texture.
`shared_from_this`	Returns a shared pointer to the current object instance.
`size`	`size` overloads
`subresourceId` [virtual]	Returns the sub-resource ID for a combination of mip-map `level,` array `layer` and `plane.`
`usage` [virtual]	Returns the usage flags for the resource.
`virtualAddress` [virtual]	Gets the address of the resource in GPU memory.
`volatileMove` [virtual]	Returns `true`, if the contents of the resource should not be copied during a move.
`weak_from_this`	Returns a weak pointer to the current object instance.
`writable` [virtual]	Returns `true`, if the resource can be bound to a read/write descriptor.

Data Members¶

Name	Description
`moved`	An event that gets invoked, after the resource has been moved to a different location, but before the old resource gets destroyed.
`moving`	An event that gets invoked before a resource is copied during a move.
`prepareMove`	An event that gets invoked to prepare a resource for a move operation.

Using Declarations¶

Name
`size`

Protected Types¶

Name	Description
`Allocator`	An allocator used to allocate the shared object.

Protected Member Functions¶

Name	Description
`IDirectX12Image` [constructor]	Constructors
`operator=`	Assignment operators
`handle` [virtual]	Returns the resource managed by the class.

Protected Static Member Functions¶

Name	Description
`create`	Generic factory method used to create instances of the shared object.

Derived Classes¶

Name	Description
`DirectX12Image`	Implements a DirectX12 `IImage`.
