TIELayer.AlphaEdgeFeathering


Declaration


property AlphaEdgeFeathering: Integer;


Description


If the layer has an alpha channel then edges of the image will be "feathered." Feathering softens the edges of an image by applying alpha transparency at a rate that is proportional to the distance to the edge (specifically, adding a gradient in the alpha channel).
The value (0 to 255) indicates the depth in pixels of the feather effect.

Default: 0 (no edge feathering)
