Collection of different elements managed by the composition manager.

Constructor & Destructor Documentation

kanzi::CompositionManager::Target::Target ( )

inlineexplicit

Empty constructor.

Target created in this way is not valid.

kanzi::CompositionManager::Target::Target ( TextureSharedPtr texture )

inlineexplicit

Constructor.

Only texture is defined.

kanzi::CompositionManager::Target::Target	(	TextureSharedPtr	texture,
		RenderbufferSharedPtr	colorRenderBuffer,
		TextureSharedPtr	depthTexture
	)

inlineexplicit

Constructor.

Specify all components and reattach framebuffers.

Parameters

texture	Main texture.
colorRenderBuffer	Color render buffer.
depthTexture	Depth texture.

Member Function Documentation

TextureSharedPtr kanzi::CompositionManager::Target::getTexture ( ) const

inline

Gets the main texture.

Main texture may exist even if its graphics format is GraphicsFormatNone.

Returns: Shared pointer to texture.

RenderbufferSharedPtr kanzi::CompositionManager::Target::getColorRenderbuffer ( ) const

inline

Gets the color renderbuffer.

Returns: Shared pointer to renderbuffer. May be empty.

TextureSharedPtr kanzi::CompositionManager::Target::getDepthTexture ( ) const

inline

Gets the depth texture.

Returns: Shared pointer to texture.

unsigned int kanzi::CompositionManager::Target::getWidth ( ) const

inline

Gets the width of the texture that has the framebuffer.

Returns: Composition target width.

unsigned int kanzi::CompositionManager::Target::getHeight ( ) const

inline

Gets the height of the texture that has the framebuffer.

Returns: Composition target height.

unsigned int kanzi::CompositionManager::Target::getSampleCount ( ) const

inline

Gets the sample count for the composition target.

This is either the sample count for the texture with the framebuffer or for the color render buffer.

Returns: Sample count as unsigned integer. Values <= 1 mean multisampling is disabled.

Sampler::AddressingMode kanzi::CompositionManager::Target::getAddressingMode ( ) const

inline

Gets the addressing mode of the composition target.

All textures in the composition target have the same sampling mode.

Returns: Addressing mode.

Sampler::Filter kanzi::CompositionManager::Target::getFilterMode ( ) const

inline

Gets the filter mode of the composition target.

All textures in the composition target have the same filter mode.

Returns: Filter mode.

Sampler::MipmapMode kanzi::CompositionManager::Target::getMipmapMode ( ) const

inline

Gets the mipmap mode of the composition target.

All textures in the composition target have the same mipmap mode.

Returns: Mipmap mode.

GraphicsFormat kanzi::CompositionManager::Target::getColorFormat ( ) const

inline

Gets the color format.

This is either the color format of the color render buffer, or that of the texture.

Returns: Graphics format. May be GraphicsFormatNone if only depth texture has meaning.

GraphicsFormat kanzi::CompositionManager::Target::getDepthStencilFormat ( ) const

inline

Gets the depth/stencil format.

Depth/stencil format is combined from the format of the texture and potentially of the depth texture.

Returns: Graphics format.

TextureSharedPtr kanzi::CompositionManager::Target::getCompositionTexture ( ) const

inline

Gets the texture used for composition.

Returns: Shared pointer to texture.

tuple<TextureSharedPtr, bool, bool> kanzi::CompositionManager::Target::getResolveSettings ( ) const

inline

Get the information for resolve target.

Returns: Triplet of resolve framebuffer and boolean flags for whether color and depth are resolved.

TextureSharedPtr kanzi::CompositionManager::Target::getAttachmentPointTexture ( Framebuffer::AttachmentPoint attachmentPoint ) const

inline

Gets the texture corresponding to a given attachment point.

Parameters

attachmentPoint Attachment point to get.

Returns: Shared pointer to texture or an empty shared pointer if no corresponding attachment point.

void kanzi::CompositionManager::Target::generateMipmaps ( )

inline

Generate mipmaps for all textures in the composition target.

void kanzi::CompositionManager::Target::reset ( )

inline

Clear all memory used by the composition target.

kanzi::CompositionManager::Target::operator bool_type ( ) const

inline
