Image mask particle system differs

[jiangcaiyang]

Thank you for helping me look at this problem.
I am imitating example to make particle masked.
First let me show you some screen shot:
This is desired:

This is problematic, the particles are not filled:

I am using these images as image mask:

Here is all my qml code:
@import QtQuick 2.2
import QtQuick.Controls 1.1
import QtQuick.Particles 2.0

ApplicationWindow {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
property url targetImageSource: "qrc:/TestSprite_2.png"

menuBar: MenuBar {
    Menu {
        title: qsTr("File")
        MenuItem {
            text: qsTr("Exit")
            onTriggered: Qt.quit();
        }
    }
}

Rectangle
{
    width: parent.width
    height: parent.height
    color: Qt.black.toString( )

    Image
    {
        id: targetImage
        anchors.centerIn: parent
        scale: 0.5
        source: targetImageSource

        MouseArea
        {
            anchors.fill: parent
            onClicked:
            {
                console.log( "The button has been clicked." );
                //parent.visible = false;
                maskParticle.start( );
            }
        }

        ParticleSystem
        {
            id: maskParticle
            anchors.fill: parent
            running: false

            ImageParticle
            {
                source: "qrc:///particleresources/glowdot.png"
                z: 2
                anchors.fill: parent
                color: "#336666CC"
                colorVariation: 0.0
            }

            Emitter
            {
                anchors.fill: parent
                emitRate: 6000
                lifeSpan: 720
                size: 10

                shape: MaskShape
                {
                    source: targetImageSource
                }
            }
        }
    }
}

Text

    font.pixelSize: 16
    text: qsTr( "This is a test particle system." )
    color: "#FFFFFF"
}

Hi,

I tested your code on Ubuntu 14.04 with Qt 5.2.1 and it works as desired.
What is your development environment ?
