Public Member Functions
virtual	~IRenderGraph ()
	Virtual destructor.
virtual void	BeginMask (bool isMaskingEnabled, bool useAlphaTest, bool drawBehind, bool drawInFront)=0
	Begin the setup of a mask render node, primitives added between this call and StartChildrenForMask define the mask.
virtual void	StartChildrenForMask ()=0
	Start defining the children (masked primitives) of a mask.
virtual void	EndMask ()=0
	End the setup of a mask render node, this marks the end of adding child primitives.
virtual void	BeginRenderToTexture (AZ::Data::Instance< AZ::RPI::AttachmentImage > attachmentImage, const AZ::Vector2 &viewportTopLeft, const AZ::Vector2 &viewportSize, const AZ::Color &clearColor)=0
	Begin rendering to a texture.
virtual void	EndRenderToTexture ()=0
	End rendering to a texture.
virtual void	AddPrimitive (LyShine::UiPrimitive *primitive, const AZ::Data::Instance< AZ::RPI::Image > &texture, bool isClampTextureMode, bool isTextureSRGB, bool isTexturePremultipliedAlpha, BlendMode blendMode)=0
	Add an indexed triangle list primitive to the render graph with given render state.
virtual void	AddAlphaMaskPrimitive (LyShine::UiPrimitive *primitive, AZ::Data::Instance< AZ::RPI::AttachmentImage > contentAttachmentImage, AZ::Data::Instance< AZ::RPI::AttachmentImage > maskAttachmentImage, bool isClampTextureMode, bool isTextureSRGB, bool isTexturePremultipliedAlpha, BlendMode blendMode)=0
	Add an indexed triangle list primitive to the render graph which will use maskTexture as an alpha (gradient) mask.
virtual LyShine::UiPrimitive *	GetDynamicQuadPrimitive (const AZ::Vector2 *positions, uint32 packedColor)=0
virtual bool	IsRenderingToMask () const =0
	Get flag that indicates we are rendering into a mask. Used to avoid masks on child mask elements.
virtual void	SetIsRenderingToMask (bool isRenderingToMask)=0
	Set flag that we are rendering into a mask. Used to avoid masks on child mask elements.
virtual void	PushAlphaFade (float alphaFadeValue)=0
	Push an alpha fade, this is multiplied with any existing alpha fade from parents.
virtual void	PushOverrideAlphaFade (float alphaFadeValue)=0
	Push a new alpha fade value, this replaces any existing alpha fade.
virtual void	PopAlphaFade ()=0
	Pop an alpha fade off the stack.
virtual float	GetAlphaFade () const =0
	Get the current alpha fade value.

GetDynamicQuadPrimitive()

virtual LyShine::UiPrimitive* LyShine::IRenderGraph::GetDynamicQuadPrimitive ( const AZ::Vector2 *  positions, uint32  packedColor  )

pure virtual

Get a dynamic quad primitive that can be added as an image primitive to the render graph The graph handles the allocation of this DynUiPrimitive and deletes it when the graph is reset This can be used if the UI component doesn't want to own the storage of the primitive. Used infrequently, e.g. for the selection rect on a text component.

Implemented in LyShine::RenderGraph.
