Gradients may be applied to shapes or to buttons only.
|To create a glow draw an ellipse and apply a radial gradient to it. Click Outer color and select "No color" option to define opaque to transparent gradient.|
Gradients are defined from left to right or from top to bottom or from the center to the edge:
Distance values control the position of the color in the gradient. By default gradient spans from 0 (left) to 255 (right). To reduce gradient area click Advanced option and modify distance values so they are closer to each other.
To add more colors to the gradient click Add Colors. Multipoint gradients can have up to 8 control points.
