<!-- $$$particles/imageparticle-brief -->
<p>This is a collection of examples using Affectors in the QML particle system.</p>

<div class="descr"> <a name="details"></a>
<p class="centerAlign"><img src="images/qml-imageparticle-example.png" alt="" /></p><p>This is a collection of small QML examples relating to using Affectors in the particle system. Each example is a small QML file emphasizing a particular type or feature.</p>
<p>All at once shows off several of the features of <a href="qml-qtquick-particles-imageparticle.html">ImageParticle</a> at the same time.</p>
<pre class="qml">
sprites: [
Sprite {
name: "bear"
source: "../../images/bear_tiles.png"
frameCount: 13
frameDuration: 120
}
]
colorVariation: 0.5
rotationVelocityVariation: 360
colorTable: "../../images/colortable.png"
</pre>
<p>Colored shows a simple <a href="qml-qtquick-particles-imageparticle.html">ImageParticle</a> with some color variation.</p>
<pre class="qml">
ImageParticle {
anchors.fill: parent
source: "qrc:///particleresources/star.png"
alpha: 0
alphaVariation: 0.2
colorVariation: 1.0
}
</pre>
<p>Color Table sets the color over life on the particles to provide a fixed rainbow effect.</p>
<pre class="qml">
source: "qrc:///particleresources/glowdot.png"
colorTable: "../../images/colortable.png"
sizeTable: "../../images/colortable.png"
</pre>
<p>Deformation spins and squishes a starfish particle.</p>
<pre class="qml">
ImageParticle {
system: sys
groups: ["goingLeft", "goingRight"]
source: "../../images/starfish_4.png"
rotation: 90
rotationVelocity: 90
autoRotation: true
}
ImageParticle {
system: sys
groups: ["goingDown"]
source: "../../images/starfish_0.png"
rotation: 180
yVector: PointDirection { y: 0.5; yVariation: 0.25; xVariation: 0.25; }
}
</pre>
<p>Rotation demonstrates the autoRotate property, so that particles rotate in the direction that they travel.</p>
<p>Sharing demonstrates what happens when multiple ImageParticles try to render the same particle. The following <a href="qml-qtquick-particles-imageparticle.html">ImageParticle</a> renders the particles inside the <a href="qml-qtquick-listview.html">ListView</a>:</p>
<pre class="qml">
ImageParticle {
anchors.fill: parent
system: particles
source: "../../images/flower.png"
alpha: 0.1
color: "white"
rotationVariation: 180
z: -1
}
</pre>
<p>The following <a href="qml-qtquick-particles-imageparticle.html">ImageParticle</a> is placed inside the list highlight, and renders the particles above the other <a href="qml-qtquick-particles-imageparticle.html">ImageParticle</a>.</p>
<pre class="qml">
ImageParticle {
anchors.fill: parent
system: particles
source: "../../images/flower.png"
color: "red"
clip: true
alpha: 1.0
}
</pre>
<p>Note that because it sets the color and alpha in this <a href="qml-qtquick-particles-imageparticle.html">ImageParticle</a>, it renders the particles in a different color. Since it doesn't specify anything about the rotation, it shares the rotation with the other <a href="qml-qtquick-particles-imageparticle.html">ImageParticle</a> so that the flowers are rotated the same way in both. Note that you can undo rotation in another <a href="qml-qtquick-particles-imageparticle.html">ImageParticle</a>, you just need to explicitly set rotationVariation to 0.</p>
<p>Sprites demonstrates using an image particle to render animated sprites instead of static images for each particle.</p>
