Adds a glow effect to a g:image element.

Syntax

iRetVal = image.addGlow(
  strColor,
  intRadius,
  intAlpha
)

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 glow is set using the intAlpha parameter of addGlow described below.
intRadius [in]: An integer that specifies the radius (or boundary), in pixels, that the glow effect extends outward from the edge of the target element.
intAlpha [in]: An integer that sets the transparency of the glow effect as a percentage from 0 (transparent) to 100 (opaque).

Remarks

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

Examples

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

\\ imgBackground is the value of the 'id' attribute for the g:background element.
var imgGlow = imgBackground.addImageObject("file://img.png", 0, 0);
imgGlow.addGlow("Color(255, 255, 0, 0)", 50, 25);
