Member Function Documentation

◆ Alloc()

static Gradient* Alloc ( )
static

Allocates a gradient data. Destroy the allocated gradient data with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

Returns
The allocated gradient data, or nullptr if the allocation failed.

◆ Free()

static void Free ( Gradient *&  grad)
static

Destructs gradient data allocated with Alloc(). Use AutoAlloc to automate the allocation and destruction based on scope.

Parameters
[in,out]gradThe gradient data to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards.

◆ InvertKnots()

Bool InvertKnots ( )

Inverts the knots.

Returns
true if the knots were successfully inverted, otherwise false.

◆ DoubleKnots()

Bool DoubleKnots ( )

Doubles the knots.

Returns
true if the knots were successfully doubled, otherwise false.

◆ DistributeKnots()

Bool DistributeKnots ( )

Distributes the knots evenly.

Returns
true if the knots were successfully distributed, otherwise false.

◆ FlushKnots()

void FlushKnots ( )

Flushes all the knots.

◆ PrepareRenderData() [1/2]

maxon::Result<maxon::GradientRenderData> PrepareRenderData ( const InitRenderStruct &  irs) const

Initializes the gradient data for render.

Parameters
[in]irsA struct with information about the upcoming gradient calculation.
Returns
RenderData on success.

◆ PrepareRenderDataWithAlpha() [1/2]

maxon::Result<GradientRenderDataTuple> PrepareRenderDataWithAlpha ( const InitRenderStruct &  irs) const

Initializes the gradient and the alpha gradint data for render.

Parameters
[in]irsA struct with information about the upcoming gradient calculation.
Returns
RenderData on success.

◆ PrepareRenderData() [2/2]

maxon::Result<maxon::GradientRenderData> PrepareRenderData ( ) const

Initializes the gradient data for render. No color transformation is applied.

Returns
RenderData on success.

◆ PrepareRenderDataWithAlpha() [2/2]

maxon::Result<GradientRenderDataTuple> PrepareRenderDataWithAlpha ( ) const

Initializes the gradient data for render. No color transformation is applied.

Returns
RenderData on success.

◆ GetKnotCount()

Int32 GetKnotCount ( ) const

Gets the number of knots.

Returns
The knot count.

◆ InsertKnot()

Int32 InsertKnot ( const maxon::GradientKnot &  knot)

Inserts a knot.

Parameters
[in]knotThe knot to insert.
Returns
The index of the inserted knot: GetKnotCount() - 1

◆ RemoveKnot()

Bool RemoveKnot ( Int32  index)

Removes a knot.

Parameters
[in]indexThe knot index. 0 <= index < GetKnotCount()
Returns
true if the knot was successfully removed, otherwise false.

◆ GetKnot()

maxon::GradientKnot GetKnot ( Int32  index) const

Gets the knot at index.

Parameters
[in]indexThe knot index. 0 <= index < GetKnotCount()
Returns
The knot.

◆ SetKnot()

void SetKnot ( Int32  index,
const maxon::GradientKnot &  k 
)

Sets knot at index.

Parameters
[in]indexThe knot index. 0 <= index < GetKnotCount()
[in]kThe knot.

◆ GetData()

GeData GetData ( Int32  id) const

[in]dataThe data.
Returns
true if successful, otherwise false.

◆ GetAlphaGradient() [1/2]

Gradient* GetAlphaGradient ( )

Gets the alpha gradient.

Returns
