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