Applies a shadow effect to subsequent drawing methods. This effect will be applied to any other 2d library drawing methods as well as any standard QBasic/QB4 drawing methods. This will also be applied to text drawing methods (e.g. Print, _PrintString). For text drawing, the shadow effect works best combination with the _KeepBackground print mode.

Syntax

G2D.Shadow clr~&, offsetX&, offsetY&, blurRadius&

Parameters

• The clr~& parameter defines the color of the shadow.
• The offsetX& and offsetY& parameters specify the amount by which the shadow is offset from the drawn item.
• The blurRadius& parameter specifies the amount of blur to apply to the shadow effect.

Examples

Example1: Apply a drop shadow to a square and text.
