TIELayer.AlphaEdgeFeathering
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.
Note: Feathering is not rendered onscreen at zoom levels above 500% to prevent performance issues
Default: 0 (no edge feathering)
