jGraduate( options, okCallback, cancelCallback )
where options is an object literal:
{
window: { title: "Pick the start color and opacity for the gradient" },
images: { clientPath: "images/" },
paint: a Paint object,
newstop: String of value "same", "inverse", "black" or "white"
OR object with one or both values {color: #Hex color, opac: number 0-1}
}
- the Paint object is:
Paint {
type: String, // one of "none", "solidColor", "linearGradient", "radialGradient"
alpha: Number representing opacity (0-100),
solidColor: String representing #RRGGBB hex of color,
linearGradient: object of interface SVGLinearGradientElement,
radialGradient: object of interface SVGRadialGradientElement,
}
$.jGraduate.Paint() -> constructs a 'none' color
$.jGraduate.Paint({copy: o}) -> creates a copy of the paint o
$.jGraduate.Paint({hex: "#rrggbb"}) -> creates a solid color paint with hex = "#rrggbb"
$.jGraduate.Paint({linearGradient: o, a: 50}) -> creates a linear gradient paint with opacity=0.5
$.jGraduate.Paint({radialGradient: o, a: 7}) -> creates a radial gradient paint with opacity=0.07
$.jGraduate.Paint({hex: "#rrggbb", linearGradient: o}) -> throws an exception?
- picker accepts the following object as input:
{
okCallback: function to call when Ok is pressed
cancelCallback: function to call when Cancel is pressed
paint: object describing the paint to display initially, if not set, then default to opaque white
}
- okCallback receives a Paint object
