getChild

colorMatrixNodeGetChild Source #

Arguments

:: (HasCallStack, MonadIO m, IsColorMatrixNode a)
=> a	`node`: a color matrix `GskRenderNode`
-> m RenderNode	Returns: The child that is getting its colors modified

Gets the child node that is getting its colors modified by the given node.

getColorMatrix

colorMatrixNodeGetColorMatrix Source #

Arguments

:: (HasCallStack, MonadIO m, IsColorMatrixNode a)
=> a	`node`: a color matrix `GskRenderNode`
-> m Matrix	Returns: a 4x4 color matrix

Retrieves the color matrix used by the node.

getColorOffset

colorMatrixNodeGetColorOffset Source #

Arguments

:: (HasCallStack, MonadIO m, IsColorMatrixNode a)
=> a	`node`: a color matrix `GskRenderNode`
-> m Vec4	Returns: a color vector

Retrieves the color offset used by the node.

new

colorMatrixNodeNew Source #

Arguments

:: (HasCallStack, MonadIO m, IsRenderNode a)
=> a	`child`: The node to draw
-> Matrix	`colorMatrix`: The matrix to apply
-> Vec4	`colorOffset`: Values to add to the color
-> m ColorMatrixNode	Returns: A new `GskRenderNode`

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.
