详细描述

The VectorImage can be used to load a vector image file and display this as an item in a Qt Quick scene. It currently supports the SVG 文件格式。

注意: This complements the approach of loading the vector image file through an 图像 元素: 图像 creates a raster version of the image at the requested size. VectorImage builds a Qt Quick scene that represents the image. This means the resulting item can be scaled and rotated without losing quality, and it will typically consume less memory than the rasterized version.

特性文档编制

fillMode : enumeration

This property defines what happens if the width and height of the VectorImage differs from the implicit size of its contents.

常量 描述
VectorImage.NoResize The contents are still rendered at the size provided by the input.
VectorImage.Stretch The contents are scaled to match the width and height of the VectorImage . (This is the default.)
VectorImage.PreserveAspectFit The contents are scaled to fit inside the bounds of the VectorImage , while preserving aspect ratio. The actual bounding rect of the contents will sometimes be smaller than the VectorImage 项。
VectorImage.PreserveAspectCrop The contents are scaled to fill the VectorImage item, while preserving the aspect ratio. The actual bounds of the contents will sometimes be larger than the VectorImage 项。

preferredRendererType : enumeration

Requests a specific backend to use for rendering shapes in the VectorImage .

常量 描述
VectorImage.GeometryRenderer Equivalent to Shape.GeometryRenderer. This backend flattens curves and triangulates the result. It will give aliased results unless multi-sampling is enabled, and curve flattening may be visible when the item is scaled.
VectorImage.CurveRenderer Equivalent to Shape.CurveRenderer. With this backend, curves are rendered on the GPU and anti-aliasing is built in. Will typically give better visual results, but at some extra cost to performance.

默认为 VectorImage.GeometryRenderer .

source : url

This property holds the URL of the vector image file to load.

VectorImage currently only supports the SVG 文件格式。
