💥 A flexible rendering engine for visualization.
isBillboard enabled and fill should be used correctly.willReadFrequently: true should be passed in when creating offscreen canvas so that the browser won't throw warning.When keepAspectRatio enabled, either width or height can be omitted and the missing one can be inferred according to raw image's aspect. In the following example, height will be calculated automatically after the Image being loaded.
new Image({
style: {
src: 'http://',
keepAspectRatio: true,
width: 100
}
})
But since the image loading process is in an async way, if we try to get bounds immediately, we'll get an empty bounds:
const image = new Image({
style: {
src: 'http://',
keepAspectRatio: true,
width: 100
}
});
image.getBounds(); // empty
The insertBefore() method inserts a node before a reference node as a child of a specified parent node.
const group1 = new Element();
const group2 = new Element();
const group3 = new Element();
const group4 = new Element();
// 2, 4, 3
group1.append(group2, group3);
group1.insertBefore(group4, group3);
If the given node already exists in the document, insertBefore() moves it from its current position to the new position. That is, it will automatically be removed from its existing parent before appending it to the specified new parent.
// 2, 3, 4 -> 2, 4, 3
group1.append(group2, group3, group4);
group1.insertBefore(group4, group3);
If refNode is null, then newNode is inserted at the end of node's child nodes.
// 2, 3, 4
group1.append(group2, group3);
group1.insertBefore(group4, null);
If refNode is not the child of parentNode, then newNode is inserted at the end of node's child nodes.
// 2, 3, 4
group1.append(group2, group3);
group1.insertBefore(group4, group5); // non-existed node
We can render component in JSX to any shape created with G API:
Online DEMO
import React, { useState, useEffect } from 'react';
import { Canvas as GCanvas, Group as GGroup } from '@antv/g';
import { Circle, render } from '@antv/react-g';
const CustomShape = () => {
const [size, setSize] = useState(100);
return <Circle cx={100} cy={100} r={size} stroke="#ff0000" lineWidth={2} />
};
useEffect(() => {
// Create Canvas & Group with G API
const canvas = new GCanvas({
container: 'C',
width: 500,
height: 500,
renderer: new Renderer(), // select a renderer
});
const group = new GGroup();
canvas.appendChild(group);
// Render to any shape with JSX syntax
render(<CustomShape />, group);
});
Removing points attribute in Polygon & Polyline won't throw error now:
polygon.removeAttribute('points');
polyline.removeAttribute('points');
Add onframe callback in gotoLandmark params:
camera.gotoLandmark('reset', {
duration: 1000,
easing: 'ease-in',
onfinish: () => {},
onframe: (t) => {
console.log(t); // [0, 1]
}
});
Skip triggering render hooks when camera changed only.
