◆ QQuickImageParticle()

QQuickImageParticle::QQuickImageParticle ( QQuickItem * parent = nullptr )

explicit

\qmltype ImageParticle \nativetype QQuickImageParticle \inqmlmodule QtQuick.Particles \inherits ParticlePainter

For visualizing logical particles using an image.

This element renders a logical particle as an image. The image can be \list

colorized
rotated
deformed
a sprite-based animation \endlist

ImageParticles implictly share data on particles if multiple ImageParticles are painting the same logical particle group. This is broken down along the four capabilities listed above. So if one ImageParticle defines data for rendering the particles in one of those capabilities, and the other does not, then both will draw the particles the same in that aspect automatically. This is primarily useful when there is some random variation on the particle which is supposed to stay with it when switching painters. If both ImageParticles define how they should appear for that aspect, they diverge and each appears as it is defined.

This sharing of data happens behind the scenes based off of whether properties were implicitly or explicitly set. One drawback of the current implementation is that it is only possible to reset the capabilities as a whole. So if you explicitly set an attribute affecting color, such as redVariation, and then reset it (by setting redVariation to undefined), all color data will be reset and it will begin to have an implicit value of any shared color from other ImageParticles.

Note: The maximum number of image particles is limited to 16383.

\qmlproperty url QtQuick.Particles::ImageParticle::source

The source image to be used.

If the image is a sprite animation, use the sprite property instead.

Since Qt 5.2, some default images are provided as resources to aid prototyping: \table \row

qrc:///particleresources/star.png
\inlineimage particles/star.png \row
qrc:///particleresources/glowdot.png
\inlineimage particles/glowdot.png \row
qrc:///particleresources/fuzzydot.png
\inlineimage particles/fuzzydot.png \endtable

Note that the images are white and semi-transparent, to allow colorization and alpha levels to have maximum effect.

\qmlproperty list<Sprite> QtQuick.Particles::ImageParticle::sprites

The sprite or sprites used to draw this particle.

Note that the sprite image will be scaled to a square based on the size of the particle being rendered.

For full details, see the \l{Sprite Animations} overview.

\qmlproperty url QtQuick.Particles::ImageParticle::colorTable

An image whose color will be used as a 1D texture to determine color over life. E.g. when the particle is halfway through its lifetime, it will have the color specified halfway across the image.

This color is blended with the color property and the color of the source image.

\qmlproperty url QtQuick.Particles::ImageParticle::sizeTable

An image whose opacity will be used as a 1D texture to determine size over life.

This property is expected to be removed shortly, in favor of custom easing curves to determine size over life.

\qmlproperty url QtQuick.Particles::ImageParticle::opacityTable

An image whose opacity will be used as a 1D texture to determine size over life.

This property is expected to be removed shortly, in favor of custom easing curves to determine opacity over life.

\qmlproperty color QtQuick.Particles::ImageParticle::color

If a color is specified, the provided image will be colorized with it.

Default is white (no change).

\qmlproperty real QtQuick.Particles::ImageParticle::colorVariation

This number represents the color variation applied to individual particles. Setting colorVariation is the same as setting redVariation, greenVariation, and blueVariation to the same number.

Each channel can vary between particle by up to colorVariation from its usual color.

Color is measured, per channel, from 0.0 to 1.0.

Default is 0.0

\qmlproperty real QtQuick.Particles::ImageParticle::redVariation The variation in the red color channel between particles.

Color is measured, per channel, from 0.0 to 1.0.

Default is 0.0

\qmlproperty real QtQuick.Particles::ImageParticle::greenVariation The variation in the green color channel between particles.

Color is measured, per channel, from 0.0 to 1.0.

Default is 0.0

\qmlproperty real QtQuick.Particles::ImageParticle::blueVariation The variation in the blue color channel between particles.

Color is measured, per channel, from 0.0 to 1.0.

Default is 0.0

\qmlproperty real QtQuick.Particles::ImageParticle::alpha An alpha to be applied to the image. This value is multiplied by the value in the image, and the value in the color property.

Particles have additive blending, so lower alpha on single particles leads to stronger effects when multiple particles overlap.

Alpha is measured from 0.0 to 1.0.

Default is 1.0

\qmlproperty real QtQuick.Particles::ImageParticle::alphaVariation The variation in the alpha channel between particles.

Alpha is measured from 0.0 to 1.0.

Default is 0.0

\qmlproperty real QtQuick.Particles::ImageParticle::rotation

If set the image will be rotated by this many degrees before it is drawn.

The particle coordinates are not transformed.

\qmlproperty real QtQuick.Particles::ImageParticle::rotationVariation

If set the rotation of individual particles will vary by up to this much between particles.

\qmlproperty real QtQuick.Particles::ImageParticle::rotationVelocity

If set particles will rotate at this velocity in degrees/second.

\qmlproperty real QtQuick.Particles::ImageParticle::rotationVelocityVariation

If set the rotationVelocity of individual particles will vary by up to this much between particles.

\qmlproperty bool QtQuick.Particles::ImageParticle::autoRotation

If set to true then a rotation will be applied on top of the particles rotation, so that it faces the direction of travel. So to face away from the direction of travel, set autoRotation to true and rotation to 180.

Default is false

\qmlproperty StochasticDirection QtQuick.Particles::ImageParticle::xVector

Allows you to deform the particle image when drawn. The rectangular image will be deformed so that the horizontal sides are in the shape of this vector instead of (1,0).

\qmlproperty StochasticDirection QtQuick.Particles::ImageParticle::yVector

Allows you to deform the particle image when drawn. The rectangular image will be deformed so that the vertical sides are in the shape of this vector instead of (0,1).

\qmlproperty EntryEffect QtQuick.Particles::ImageParticle::entryEffect

This property provides basic and cheap entrance and exit effects for the particles. For fine-grained control, see sizeTable and opacityTable.

Acceptable values are

\value ImageParticle.None Particles just appear and disappear. \value ImageParticle.Fade Particles fade in from 0 opacity at the start of their life, and fade out to 0 at the end. \value ImageParticle.Scale Particles scale in from 0 size at the start of their life, and scale back to 0 at the end.

The default value is ImageParticle.Fade.

\qmlproperty bool QtQuick.Particles::ImageParticle::spritesInterpolate

If set to true, sprite particles will interpolate between sprite frames each rendered frame, making the sprites look smoother.

Default is true.

\qmlproperty Status QtQuick.Particles::ImageParticle::status

The status of loading the image.

Called on the render thread when it is time to sync the state of the item with the scene graph.

The function is called as a result of QQuickItem::update(), if the user has set the QQuickItem::ItemHasContents flag on the item.

The function should return the root of the scene graph subtree for this item. Most implementations will return a single QSGGeometryNode containing the visual representation of this item. oldNode is the node that was returned the last time the function was called. updatePaintNodeData provides a pointer to the QSGTransformNode associated with this QQuickItem.

QSGNode *MyItem::updatePaintNode(QSGNode *node, UpdatePaintNodeData *)
{
    QSGSimpleRectNode *n = static_cast<QSGSimpleRectNode *>(node);
    if (!n) {
        n = new QSGSimpleRectNode();
        n->setColor(Qt::red);
    }
    n->setRect(boundingRect());
    return n;
}

The main thread is blocked while this function is executed so it is safe to read values from the QQuickItem instance and other objects in the main thread.

If no call to QQuickItem::updatePaintNode() result in actual scene graph changes, like QSGNode::markDirty() or adding and removing nodes, then the underlying implementation may decide to not render the scene again as the visual outcome is identical.

Warning: It is crucial that graphics operations and interaction with the scene graph happens exclusively on the render thread, primarily during the QQuickItem::updatePaintNode() call. The best rule of thumb is to only use classes with the "QSG" prefix inside the QQuickItem::updatePaintNode() function.; This function is called on the render thread. This means any QObjects or thread local storage that is created will have affinity to the render thread, so apply caution when doing anything other than rendering in this function. Similarly for signals, these will be emitted on the render thread and will thus often be delivered via queued connections.

Note: All classes with QSG prefix should be used solely on the scene graph's rendering thread. See \l {Scene Graph and Rendering} for more information.
