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:
GskRenderNodeThe node to draw.
The data is owned by the caller of the function. color_matrix-
Type:
graphene_matrix_tThe matrix to apply.
The data is owned by the caller of the function. color_offset-
Type:
graphene_vec4_tValues 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. |
