Create interesting effects by changing the way pixels of one layer blend with pixels of underlying layers. Paint Shop Pro contains a variety of blend modes that specify how it blends pixels. The image displays the blended pixels, but layers are not actually combined.
By default, each layer has a blend mode of Normal, which blends pixels based on the opacity of the selected layer. The pixels of the selected layer are blended with the combination of all underlying layers, not just the layer directly beneath it.
To limit the pixels that the blend mode affects, set the blend range. See Setting Blend Ranges.
To set the blend mode of a layer:
On the Layers palette, click the Blend Mode drop-list of the layer you want to set and select the blend mode from the list. You can also set a blend mode in the Layer Properties dialog. For descriptions of the blend modes, see About Blend Modes.
