Scatter

</h1>
|
|
<p>
|
|
Scatter objects are UI elements that can be rotated, scaled or moved around,
|
|
which typically leads to "scattered" layouts. Scatters come in two flavours:
|
|
DOM Scatters are working with arbitrary DOM elements, wheras PIXI Scatter
|
|
work with PIXI Containers and DisplayObjects within the PIXI scene graph. Here
|
|
we describe the more basic DOM scatter.
|
|

|
|
<p>Let's look at an example.</p>
|
|
<div id="main" class="grayBorder interactive" style="position: relative; width: 100%; height: 280px;">
|
|
<!-- Note that we need to set draggable to false to avoid conflicts. The DOM elements
|
|
must also be positioned absolutely. -->
|
|
<img id="women" draggable="false" style="position: absolute;" src="examples/women.jpeg" />
|
|
<img id="king" draggable="false" style="position: absolute;" src="examples/king.jpeg" />
|
|
|
|
<canvas id="debugCanvas" height="280" style="z-index: 100000; pointer-events: none; position: absolute; border: 1px solid blue;">
|
|
Canvas not supported.

|
<script class="doctest">
|
|
let dx = 44
|
|
|
|
let app = new App()
|
|
let scatterContainer = new DOMScatterContainer(main)
|
|
let angle = 0 // 15
|
|
for(let key of ['women', 'king']) {
|
|
let image = document.getElementById(key)
|
|
// The DOMScatter needs initial width and height. Therefore we
|
|
// define the scatter when the image size is known, i.e. after loading...
|
|
image.onload = (e) => {
|
|
let scatter = new DOMScatter(image, scatterContainer, {
|
|
x: dx,
|
|

|
Interactive Content
|
|
</h1>
|
|
<p>
|
|
Scatter objects may contain interactive HTML structures. There is one major flag that allows
|
|
to simulate click events by using taps. If the scatter detects a tap it looks for clickable
|
|
elements under or nearby the event position and calls the click handler. Thus gestures
|
|
can be disambiguated as moves, zooms. or taps.
