Constructor

GskColorMatrixNodenew

Declaration [src]

GskRenderNode*
gsk_color_matrix_node_new (
  GskRenderNode* child,
  const graphene_matrix_t* color_matrix,
  const graphene_vec4_t* color_offset
)

Description [src]

Creates a GskRenderNode that will drawn the child with color_matrix.

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

Type: GskRenderNode

The node to draw.

The data is owned by the caller of the function.
color_matrix

Type: graphene_matrix_t

The matrix to apply.

The data is owned by the caller of the function.
color_offset

Type: graphene_vec4_t

Values to add to the color.

The data is owned by the caller of the function.

Return value

Type: GskColorMatrixNode

A new GskRenderNode.

The caller of the function takes ownership of the data, and is responsible for freeing it.
