Creates a linear gradient of many colors.
Requires graphicsbuilder-ext-jdk6 and Java6+.
Properties
| Property | Default | Notes |
|---|---|---|
| x1 | 0 | |
| y1 | 0 | |
| x2 | 100 | |
| y2 | 0 | |
| cycle | 'nocycle' | value must be any of ['nocycle','reflect','repeat] or any MultipleGradientPaint.CycleMethod |
| stretch | false | Scales the gradient to fit the Shape's bounds |
| fit | true | Scales the gradient retaining the aspect ratio |
| stops | [] | must define at least two stops |
| linkTo | a reference to a linearGradient or a radialGradient |
If linkTo is used, then this gradient will reuse the referenced one's stops, new stops may be added to this gradient though.
Stops
| Property | Default | Notes |
|---|---|---|
| offset | a float value in the range [0..1] | |
| color | a Color or a color string | |
| opacity | must be in the range [0..1] |
Example
4 rectangles, each one with a diagonal gradient
def stops = {
def offsets = [0,0.5,1]
def colors = ['black','red','blue']
(0..2).each{ stop( offset: offsets[it], color: colors[it] ) }
}
rect( x: 0, y: 0, width: 100, height: 100 ){
linearGradient( x1: 0, y1: 0, x2: 50, y2: 50 ){ stops() }
}
rect( x: 100, y: 0, width: 100, height: 100 ){
linearGradient( x1: 50, y1: 0, x2: 0, y2: 50 ){ stops() }
}
rect( x: 0, y: 100, width: 100, height: 100 ){
linearGradient( x1: 0, y1: 50, x2: 50, y2: 0 ){ stops() }
}
rect( x: 100, y: 100, width: 100, height: 100 ){
linearGradient( x1: 50, y1: 50, x2: 0, y2: 0 ){ stops() }
}
Different settings for fit, stretch and cycle
def stops = {
def offsets = [0,0.5,1]
def colors = ['black','red','blue']
(0..2).each{ stop( offset: offsets[it], color: colors[it] ) }
}
inearGradient( x1: 0, y1: 0, x2: 50, y2: 50, id: 'g1' ){ stops() }
rect( x: 0, y: 0, width: 100, height: 100, fill: g1 )
circle( cx: 150, cy: 50, radius: 50, fill: g1 )
rect( x: 0, y: 100, width: 200, height: 100, fill: g1 )
