Adds a shadow effect to a g:image element.

Syntax

iRetVal = image.addShadow(
  strColor,
  intRadius,
  intAlpha,
  intDeltaX,
  intDeltaY
)

Parameters

strColor [in]: A named Windows color (such as "Black") or a color in the format "Color(Alpha, R, G, B)" where the Alpha, R, G, and B values can range from 0 to 255.

Note

If using the "Color(Alpha, R, G, B)" specification, the Alpha value is superfluous. The transparency of the shadow is set using the intAlpha parameter of addShadow described below.
intRadius [in]: An integer that specifies the radius (or boundary), in pixels, that the shadow effect extends outward from the edge of the target element.
intAlpha [in]: An integer that sets the transparency of the shadow effect. The value can range from 0 (transparent) to 100 (opaque).
intDeltaX [in]: The offset, in pixels, from the leftmost edge of the target element.
intDeltaY [in]: The offset, in pixels, from the rightmost edge of the target element.

Remarks

The opacity of the target element must be set to a value of at least 1 for the shadow effect to be visible.

Examples

The following example demonstrates how to add a shadow effect to a g:image element.

\\ imgBackground is the value of the 'id' attribute for the g:background element.
var imgShadow = imgBackground.addImageObject("file://img.png", 0, 0);
imgShadow.addShadow("black", 50, 50, 0, 0);
