numberOfBalls
Number of balls that will be drawn in the image. Only positive values are accepted.
size
Average balls size, in pixels. Only positive values are accepted.
sizeVariation
Balls size variation. Valid values range from 0 to 100. Use 0 to have all balls the same size. Use 100 to have the size vary from 0 to 2 X uSize.
highLightAngle
Light source direction of the highlight color on the ball. This value is in hundredths of degrees (+/-). A positive value will rotate the highlight color clockwise, while a negative value will rotate the highlight color counter-clockwise. Valid values range from -36000 to + 36000.
highLightColor
Highlight color.
backGroundColor
Backgound color.
shadingColor
Shade (or gradient) color.
ripple
The number of shades that are used to produce the background. This value is divided internally by 100. For example, if lRipple = 200 the actual frequency is 2.
ballColors
An array of ball colors.
ballColorOpacity
Average ball color opacity. Valid values range from: 0 to 255 for 8-bit, 0 to 4095 for 12-bit, 0 to 65535 for 16-bit.
ballColorOpacityVariation
Ball color opacity variation. Valid values range from 0 to 100. Use 0 to have all pixels assigned the same opacity. Use 100 to have the opacity vary from 0 to 2 X ballColorOpacity.
flags
Enumeration that indicates the background color , shade (or gradient) type, ball type and ball color type.
Initializes a new Leadtools.ImageProcessing.SpecialEffects.ColoredBallsCommand with explicit parameters.
