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 GskRenderNode
 

The node to draw.

 The data is owned by the caller of the function.
color_matrix const graphene_matrix_t*
 

The matrix to apply.

 The data is owned by the caller of the function.
color_offset const graphene_vec4_t*
 

Values to add to the color.

 The data is owned by the caller of the function.

Return value

Returns: GskColorMatrixNode
 

A new GskRenderNode

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