Constructor Details

ColorMatrixNode

public ColorMatrixNode(MemorySegment address)

Create a ColorMatrixNode proxy 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

asParent

protected ColorMatrixNode asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class RenderNode

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
