SDFRectTexture

Since 2.2.1

SDFRectTexture draws a rounded rectangle using an SDF (Signed Distance Field) GPU shader. It produces sharp, anti-aliased edges at any size. Supports per-corner radii, an optional stroke border, and smooth CSS-transition interpolation.

Registry name: sdf_rect_texture
LSS function: rect(...) / sdf(...)

Extends TransformTexture — supports rotate(), scale(), transform().

Usage

JavaKotlinKubeJS

// Filled rounded rect
IGuiTexture panel = new SDFRectTexture()
    .setColor(0xFF2A2A2A)
    .setRadius(6f);

// Rounded rect with a white stroke
IGuiTexture bordered = new SDFRectTexture()
    .setColor(0xFF1A1A1A)
    .setRadius(4f)
    .setStroke(1f)
    .setBorderColor(0xFFFFFFFF);

// Static factory
IGuiTexture simple = SDFRectTexture.of(0xFF3A3A3A);

val panel = SDFRectTexture()
    .setColor(0xFF2A2A2A.toInt())
    .setRadius(6f)

val bordered = SDFRectTexture.of(0xFF1A1A1A.toInt())
    .setRadius(4f)
    .setStroke(1f)
    .setBorderColor(0xFFFFFFFF.toInt())

let panel = new SDFRectTexture()
    .setColor(0xFF2A2A2A)
    .setRadius(6);

let bordered = SDFRectTexture.of(0xFF1A1A1A)
    .setRadius(4)
    .setStroke(1)
    .setBorderColor(0xFFFFFFFF);

Fields

Name	Type	Description
`color`	`int`	Fill colour (ARGB). Default: `0xFFFFFFFF`.
`borderColor`	`int`	Stroke colour (ARGB). Default: `0xFF000000`.
`radius`	`Vector4f`	Per-corner radii: `x` = bottom-left, `y` = bottom-right, `z` = top-right, `w` = top-left.
`stroke`	`float`	Border stroke width in pixels. `0` disables the border.

Methods

Method	Returns	Description
`setColor(int)`	`SDFRectTexture`	Sets the fill colour.
`setBorderColor(int)`	`SDFRectTexture`	Sets the stroke colour.
`setRadius(float)`	`SDFRectTexture`	Sets all four corner radii to the same value.
`setRadius(Vector4f)`	`SDFRectTexture`	Sets per-corner radii.
`setStroke(float)`	`SDFRectTexture`	Sets the stroke width.
`copy()`	`SDFRectTexture`	Returns a deep copy.
`interpolate(IGuiTexture, float)`	`IGuiTexture`	Blends all properties toward another `SDFRectTexture`.
`SDFRectTexture.of(int)`	`SDFRectTexture`	Static factory — creates a rect with the given fill colour.
