Functions ¶

func GioPaint ¶

func GioPaint(ops *op.Ops, data []byte, rect image.Rectangle, opts ...decode.DecodeOption)

func ImagePaint ¶

func ImagePaint(ops *op.Ops, data []byte, rect image.Rectangle, opts ...decode.DecodeOption)

func Widget ¶ added in v0.1.2

func Widget(data []byte, width, height unit.Dp, options ...Option) (layout.Widget, error)

Widget creates a layout widget for rendering IconVG vector graphics data. It supports two rendering backends: a default Gio clip.Path implementation and an optional image-based raster backend (enabled via WithImageBackend()). The widget handles aspect ratio preservation following the SVG specification's "xMidYMid meet" behavior, which scales the image to fit the viewport while maintaining proportions and centering it both horizontally and vertically.

The data parameter accepts the raw IconVG bytes, while width and height specify the desired dimensions in device-independent pixels (Dp). Additional rendering options can be provided through the variadic options parameter.
