Constructor Details

ColorMatrixNode

public ColorMatrixNode(MemorySegment address)

Create a ColorMatrixNode instance for the provided memory address.

Parameters:

address - the memory address of the native object

ColorMatrixNode

public ColorMatrixNode(RenderNode child,
 Matrix colorMatrix,
 Vec4 colorOffset)

Creates a GskRenderNode that will drawn the child with colorMatrix.

In particular, the node will transform colors by applying

pixel = transpose(color_matrix) * pixel + color_offset

for every pixel. The transformation operates on unpremultiplied colors, with color components ordered R, G, B, A.

Parameters:

child - The node to draw

colorMatrix - The matrix to apply

colorOffset - Values to add to the color

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ColorMatrixNode class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected ColorMatrixNode asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class RenderNode

Returns:

the instance as if it were its parent type

getChild

public RenderNode getChild()

Gets the child node that is getting its colors modified by the given node.

Returns:

The child that is getting its colors modified

getColorMatrix

public Matrix getColorMatrix()

Retrieves the color matrix used by the node.

Returns:

a 4x4 color matrix

getColorOffset

public Vec4 getColorOffset()

Retrieves the color offset used by the node.

Returns:

a color vector
