示例1: constructor
constructor(radius: number, precision: number) {
this.r = radius;
this.p = precision;
this.circleGenerator = d3Geo.geoCircle<Circulator, [number, number] | undefined>()
.radius(function (datum) {
let t: Circulator = this;
let d: [number, number] | undefined = datum;
return this.r;
})
.precision(function (datum) {
let t: Circulator = this;
let d: [number, number] | undefined = datum;
return this.p;
})
.center(function (datum) {
let t: Circulator = this;
let d: [number, number] | undefined = datum;
return d ? d : [0, 0];
});
}示例2: rotation
let rotation: d3Geo.GeoRotation = d3Geo.geoRotation([90, 45]);
let rotation2: d3Geo.GeoRotation = d3Geo.geoRotation([90, 45, 27.5]);
// use rotation --------------------------------------------------------
let point: [number, number] = rotation([54, 2]);
let inverted: [number, number] = rotation.invert([54, 2]);
// ----------------------------------------------------------------------
// Spherical Shapes - geoCircle
// ----------------------------------------------------------------------
// Create GeoCircleGenerator ============================================
// simple use case
let circleGeneratorSimple: d3Geo.GeoCircleGenerator<any, any> = d3Geo.geoCircle();
// complex use as part of object
class Circulator {
constructor(radius: number, precision: number) {
this.r = radius;
this.p = precision;
this.circleGenerator = d3Geo.geoCircle<Circulator, [number, number] | undefined>()
.radius(function (datum) {
let t: Circulator = this;
let d: [number, number] | undefined = datum;
return this.r;
})
.precision(function (datum) {
let t: Circulator = this;示例3: rotation
