Members
contentBounds
Type: D2D1_RECT_F
The content bounds of the layer. Content outside these bounds is not guaranteed to render.
geometricMask
Type: ID2D1Geometry*
The geometric mask specifies the area of the layer that is composited into the render target.
maskAntialiasMode
Type: D2D1_ANTIALIAS_MODE
A value that specifies the antialiasing mode for the geometricMask.
maskTransform
Type: D2D1_MATRIX_3X2_F
A value that specifies the transform that is applied to the geometric mask when composing the layer.
opacity
Type: FLOAT
An opacity value that is applied uniformly to all resources in the layer when compositing to the target.
opacityBrush
Type: ID2D1Brush*
A brush that is used to modify the opacity of the layer. The brush is mapped to the layer, and the alpha channel of each mapped brush pixel is multiplied against the corresponding layer pixel.
layerOptions
Type: D2D1_LAYER_OPTIONS1
Additional options for the layer creation.
