详细描述

BorderImageMesh provides BorderImage -like capabilities to a ShaderEffect without the need for a potentially costly ShaderEffectSource .

The following are functionally equivalent:

BorderImage {    id: borderImage    border {        left: 10        right: 10        top: 10        bottom: 10    }    source: "myImage.png"    visible: false}ShaderEffectSource {    id: effectSource    sourceItem: borderImage    visible: false}ShaderEffect {    property var source: effectSource    ...}
Image {    id: image    source: "myImage.png"    visible: false}ShaderEffect {    property var source: image    mesh: BorderImageMesh {        border {            left: 10            right: 10            top: 10            bottom: 10        }        size: image.sourceSize    }    ...}

But the BorderImageMesh version can typically be better optimized.

horizontalTileMode : enumeration

verticalTileMode : enumeration

This property describes how to repeat or stretch the middle parts of an image.

  • BorderImage .Stretch - Scales the image to fit to the available area.
  • BorderImage .Repeat - Tile the image until there is no more space. May crop the last image.
  • BorderImage .Round - Like Repeat, but scales the images down to ensure that the last image is not cropped.

The default tile mode for each property is BorderImage .Stretch.


border group

border.bottom : int

border.left : int

border.right : int

border.top : int

The 4 border lines (2 horizontal and 2 vertical) break the image into 9 sections, as shown below:

Each border line (left, right, top, and bottom) specifies an offset in pixels from the respective edge of the mesh. By default, each border line has a value of 0.

For example, the following definition sets the bottom line 10 pixels up from the bottom of the mesh:

BorderImageMesh {    border.bottom: 10    // ...}

size : size

The base size of the mesh. This generally corresponds to the sourceSize of the image being used by the ShaderEffect .
