public: LightCommand( array<LightCommandData>^ data, int bright, int ambient, RasterColor ambientColor ) |
Parameters
- data
- An array of LightCommandData structures that contains information on each light source.
- bright
- Value that represents the brightness of the ambient light of the entire image. This can be any number that is 0 or greater. If it is 0 the image will be black. This value is divided internally by 100.
- ambient
- Factor used when mixing the ambient color with the image. This property only accepts positive values.
- ambientColor
- Specifies the ambient color of the light sources in the LightCommandData array.
Run the LightCommand on an image to change the red color by rotating its hue 90 degree.
