addCone(iX1, iY1, iZ1, iX2, iY2, iRed, iGreen, iBlue, iStrength, iSpread)
Parameters
iX1 Required. Integer that specifies the left coordinate of the light source.
//必填，整型，指明光源的X坐标
iY1 Required. Integer that specifies the top coordinate of the light source.
//必填，整型，指明光源的Y坐标
iZ1 Required. Integer that specifies the z-axis level of the light source.
//必填，整型，指明光源高度
iX2 Required. Integer that specifies the left coordinate of the target light focus.
//必填，整型，指明光源焦点的X坐标
iY2 Required. Integer that specifies the top coordinate of the target light focus.
//必填，整型，指明光源焦点的Y坐标
iRed Required. Integer that specifies the red value. The value can range from 0 (lowest saturation) to 255 (highest saturation).
iGreen Required. Integer that specifies the green value. The value can range from 0 (lowest saturation) to 255 (highest saturation).
iBlue Required. Integer that specifies the blue value. The value can range from 0 (lowest saturation) to 255 (highest saturation).
//iRed、iGreen、iBlue 光源颜色的RGB三原色分量，必填，0~255整数
iStrength Required. Integer that specifies the intensity of the light filter. The value can range from 0 (lowest intensity) to 100 (highest intensity).
//光源长度，0~100
iSpread Required. Integer that specifies the angle, or spread, between the vertical position of the light source and the surface of the object. The angle can range from 0 to 90 degrees. Smaller angle values produce a smaller cone of lightlarger values produce an oblique oval or circle of light.
//角度
我想如果只要字体和图片产生阴影效果
用滤镜Shadow就可以实现呀
Filter：Shadow（Color=color，Direction=direction）
可以在指定的方向建立投影，Color是指定发光的颜色，Strength指定发光的强度，参数值从1到255
使对象的边缘产生类似发光的效可用滤镜
Filter：Glow（Color=color，Strength=strength）
Direction参数用来指定投影的方向
举个例，比如说你想让你的空间名产生发光和阴影效果，可以这样写
#header div.tit{top:4pxLEFT:100pxfont-size:30pxfont-family:楷体FILTER:Glow(Color=#33ADFF,Strength=4) Shadow(Color=#003355,Direction=180)color:#FFF}
