parameters
| iX1 |
Required.
Integerthat specifies the left coordinate of the light source. |
| iY1 |
Required.
Integerthat specifies the top coordinate of the light source. |
| iZ1 |
Required.
Integerthat specifies the z-axis level of the light source. |
| iX2 |
Required.
Integerthat specifies the left coordinate of the target light focus. |
| iY2 |
Required.
Integerthat specifies the top coordinate of the target light focus. |
| iRed |
Required.
Integerthat specifies the red value. The value can range from 0 (lowest saturation) to 255 (highest saturation). |
| iGreen |
Required.
Integerthat specifies the green value. The value can range from 0 (lowest saturation) to 255 (highest saturation). |
| iBlue |
Required.
Integerthat specifies the blue value. The value can range from 0 (lowest saturation) to 255 (highest saturation). |
| iStrength |
Required.
Integerthat specifies the intensity of the light filter. The value can range from 0 (lowest intensity) to 100 (highest intensity). |
| iSpread |
Required.
Integerthat 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 light; larger values produce an oblique oval or circle of light. |
Return Value
No return value.
Remarks
The cone light fades with distance from the target x,y position. The light displays a hard edge at the near edge of its focus and fades gradually as it reaches its distance threshold.
