Glow Style Type

The Glow Style Type lets you apply a glowing outline around any map object. It has the following configurable properties:

Properties	Description
Color	The color of the glow in hex code (without #). The default value is FF0000
Alpha	The alpha transparency value for the shadow color. Valid values are 0 to 100. For example, 25 sets a transparency value of 25%
blurX	The amount of horizontal blur. Valid values are 0 to 255. The default value is 8. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values
blurry	The amount of vertical blur. Valid values are 0 to 255. The default value is 8. Values that are a power of 2 (such as 2, 4, 8, 16 and 32) are optimized to render more quickly than other values
Strength	The strength of the imprint or spread. The higher the value, the more color is imprinted and the stronger the contrast between the glow and the background. Valid values are 0 to 255. The default is 2
Quality	The number of times to apply the effect. Valid values are 0 to 15. The default value is 1, which is equivalent to low quality. A value of 2 is medium quality, and a value of 3 is high quality. Glows with lower values are rendered quicker.

To define a glow's color and alpha, you use the following code:
<style name='MyFirstGlow' type='Glow' color='FF5904' alpha='75'/>

You can configure the blur amount of glow as under:
<style name='MyFirstGlow' type='Glow' color='FF5904' alpha='75' blurX='12' blurY='12'/>

You can also control the glow strength and quality to get better results.
