Abstract
In various example embodiments, a system and method are provided for blending a group of layers with multiple blend modes such that additional style layers are applied to the layer group's combined shape, and clipped as if the style layers were applied to a single layer with the combined transparency of the group's layers. In example embodiments, for each of a plurality of layers: a group background is blended behind a group buffer, one of the plurality of layers is blended on top of the group buffer while ignoring a transparency of the group buffer, and the background is factored out from the group buffer. When the blending is complete, a style or effect is applied to the blended layers, and the background is blended behind the group result such that the group result transparency such that the style is clipped to the group result.
