TIEImageEnGlobalSettings.LayerShadowAlphaThreshold

Declaration

property LayerShadowAlphaThreshold: Integer;

Description

Specifies the threshold separating foreground and background pixels when applying a soft shadow to a layer.
The range is 0 to 255. A low value may show color artifacts where anti-aliased curves merge with the shadow. A value too high will lessen the anti-aliasing of curves (making them look blocky).

Default: 50

Examples

// Increase the alpha background threshold (reducing color merging artifacts)
IEGlobalSettings().LayerShadowAlphaThreshold := 172;
ImageEnView1.Update();

// Decrease the alpha background threshold (improving anti-aliasing)
IEGlobalSettings().LayerShadowAlphaThreshold := 0;
ImageEnView1.Update();
