Specifies that images on the local filesystem should be loaded asynchronously in a separate thread. The default value is false, causing the user interface thread to block while the image is loaded. Setting asynchronous to true is useful where maintaining a responsive user interface is more desirable than having images immediately visible.

Note that this property is only valid for images read from the local filesystem. Images loaded via a network resource (e.g. HTTP) are always loaded asynchronously.

Specifies whether the image should be cached. The default value is true. Setting cache to false is useful when dealing with large images, to make sure that they aren't cached at the expense of small 'ui element' images.

Set this property to define what happens when the source image has a different size than the item.

• Image.Stretch - the image is scaled to fit
• Image.PreserveAspectFit - the image is scaled uniformly to fit without cropping
• Image.PreserveAspectCrop - the image is scaled uniformly to fill, cropping if necessary
• Image.Tile - the image is duplicated horizontally and vertically
• Image.TileVertically - the image is stretched horizontally and tiled vertically
• Image.TileHorizontally - the image is stretched vertically and tiled horizontally
• Image.Pad - the image is not transformed

Image {
    width: 130; height: 100
    source: "qtlogo.png"
}

Image {
    width: 130; height: 100
    fillMode: Image.PreserveAspectFit
    source: "qtlogo.png"
}

Image {
    width: 130; height: 100
    fillMode: Image.PreserveAspectCrop
    source: "qtlogo.png"
    clip: true
}

Image {
    width: 120; height: 120
    fillMode: Image.Tile
    horizontalAlignment: Image.AlignLeft
    verticalAlignment: Image.AlignTop
    source: "qtlogo.png"
}

Image {
    width: 120; height: 120
    fillMode: Image.TileVertically
    verticalAlignment: Image.AlignTop
    source: "qtlogo.png"
}

Image {
    width: 120; height: 120
    fillMode: Image.TileHorizontally
    verticalAlignment: Image.AlignLeft
    source: "qtlogo.png"
}

Note that clip is false by default which means that the item might paint outside its bounding rectangle even if the fillMode is set to PreserveAspectCrop.

Sets the horizontal and vertical alignment of the image. By default, the image is center aligned.

The valid values for horizontalAlignment are Image.AlignLeft, Image.AlignRight and Image.AlignHCenter. The valid values for verticalAlignment are Image.AlignTop, Image.AlignBottom and Image.AlignVCenter.

This property holds whether the image uses mipmap filtering when scaled or transformed.

Mipmap filtering gives better visual quality when scaling down compared to smooth, but it may come at a performance cost (both when initializing the image and during rendering).

By default, this property is set to false.

This QML property was introduced in Qt 5.3.

See also smooth.

This property holds whether the image should be horizontally inverted (effectively displaying a mirrored image).

The default value is false.

These properties hold the size of the image that is actually painted. In most cases it is the same as width and height, but when using a fillMode PreserveAspectFit or fillMode PreserveAspectCrop paintedWidth or paintedHeight can be smaller or larger than width and height of the Image item.

These properties hold the size of the image that is actually painted. In most cases it is the same as width and height, but when using a fillMode PreserveAspectFit or fillMode PreserveAspectCrop paintedWidth or paintedHeight can be smaller or larger than width and height of the Image item.

This property holds the progress of image loading, from 0.0 (nothing loaded) to 1.0 (finished).

See also status.

This property holds whether the image is smoothly filtered when scaled or transformed. Smooth filtering gives better visual quality, but it may be slower on some hardware. If the image is displayed at its natural size, this property has no visual or performance effect.

By default, this property is set to true.

See also mipmap.

Image can handle any image format supported by Qt, loaded from any URL scheme supported by Qt.

The URL may be absolute, or relative to the URL of the component.

See also QQuickImageProvider.

This property holds the actual width and height of the loaded image.

Unlike the width and height properties, which scale the painting of the image, this property sets the actual number of pixels stored for the loaded image so that large images do not use more memory than necessary. For example, this ensures the image in memory is no larger than 1024x1024 pixels, regardless of the Image's width and height values:

Rectangle {
    width: ...
    height: ...

    Image {
       anchors.fill: parent
       source: "reallyBigImage.jpg"
       sourceSize.width: 1024
       sourceSize.height: 1024
    }
}

If the image's actual size is larger than the sourceSize, the image is scaled down. If only one dimension of the size is set to greater than 0, the other dimension is set in proportion to preserve the source image's aspect ratio. (The fillMode is independent of this.)

If both the sourceSize.width and sourceSize.height are set the image will be scaled down to fit within the specified size, maintaining the image's aspect ratio. The actual size of the image after scaling is available via Item::implicitWidth and Item::implicitHeight.

If the source is an intrinsically scalable image (eg. SVG), this property determines the size of the loaded image regardless of intrinsic size. Avoid changing this property dynamically; rendering an SVG is slow compared to an image.

If the source is a non-scalable image (eg. JPEG), the loaded image will be no greater than this property specifies. For some formats (currently only JPEG), the whole image will never actually be loaded into memory.

sourceSize can be cleared to the natural size of the image by setting sourceSize to undefined.

Note: Changing this property dynamically causes the image source to be reloaded, potentially even from the network, if it is not in the disk cache.

This property holds the status of image loading. It can be one of:

• Image.Null - no image has been set
• Image.Ready - the image has been loaded
• Image.Loading - the image is currently being loaded
• Image.Error - an error occurred while loading the image

Use this status to provide an update or respond to the status change in some way. For example, you could:

• Trigger a state change:

  State { name: 'loaded'; when: image.status == Image.Ready }

• Implement an onStatusChanged signal handler:

  Image {
      id: image
      onStatusChanged: if (image.status == Image.Ready) console.log('Loaded')
  }

• Bind to the status value:

  Text { text: image.status == Image.Ready ? 'Loaded' : 'Not loaded' }

See also progress.

Sets the horizontal and vertical alignment of the image. By default, the image is center aligned.

The valid values for horizontalAlignment are Image.AlignLeft, Image.AlignRight and Image.AlignHCenter. The valid values for verticalAlignment are Image.AlignTop, Image.AlignBottom and Image.AlignVCenter.
