Initializes a new
ChangeHueSaturationIntensityCommand class object with explicit parameters.
Supported in Silverlight, Windows Phone 7
Syntax
Parameters
- hue
- Angular amount to change the hue, in hundredths of a degree. Valid values range from -18000 through 18000. This value is divided internally by 100.
- saturation
- Percentage amount to change saturation, in tenths of a percent. Valid values range from -1000 through 1000. This value is divided internally by 10. Negative values decrease the saturation of colors. Positive values increase the saturation. The saturation level is increased or decreased by a percentage of its present saturation level. For example, an increase of 20 of the current saturation level "L" will raise the new saturation level "L1" to a value L = 0.20 * L. Likewise, increasing the saturation level 100 doubles the saturation level (L1 = L + 1.0 * L). Decreasing the saturation level 100 will set the new saturation level to 0. This process is carried out for every pixel. The saturation is set to 1000 (maximum value) if the new value exceeds 1000).
- intensity
- Percentage amount to change the intensity , in tenths of a percent. Valid values range from -1000 (black) through 1000 (white). This value is divided internally by 10. Positive values increase (or lighten) the brightness of the image. Negative values decrease (or darken) the brightness of the image.
- data
- An array of ChangeHueSaturationIntensityCommandData classes that provides information about the color ranges used by this method.
Example
Run the ChangeHueSaturationIntensityCommand on an image to change its hue, saturation, and brightness and change the red color to green.
