RectTexture

Since 2.2.1

RectTexture draws a rounded rectangle using CPU-side tessellation. It is a fallback alternative to SDFRectTexture for environments where the SDF shader is unavailable. Both classes expose the same properties.

Registry name: rect_texture

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

For most use cases, prefer SDFRectTexture which provides better visual quality at all sizes. Use RectTexture only when you need CPU-side rendering.

Usage

JavaKotlinKubeJS

// Filled rounded rect
IGuiTexture panel = new RectTexture()
    .setColor(0xFF2A2A2A)
    .setRadius(new Vector4f(6, 6, 6, 6));

// With stroke
IGuiTexture bordered = new RectTexture()
    .setColor(0xFF1A1A1A)
    .setRadius(new Vector4f(4, 4, 4, 4))
    .setStroke(1f)
    .setBorderColor(0xFFFFFFFF);

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

val panel = RectTexture()
    .setColor(0xFF2A2A2A.toInt())
    .setRadius(Vector4f(6f, 6f, 6f, 6f))

val simple = RectTexture.of(0xFF3A3A3A.toInt())

let panel = new RectTexture()
    .setColor(0xFF2A2A2A)
    .setStroke(1)
    .setBorderColor(0xFFFFFFFF);

let simple = RectTexture.of(0xFF3A3A3A);

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. `0` disables the border.
`cornerSegments`	`int`	Number of line segments per corner arc. Higher = smoother but more vertices. Default: `8`.

Methods

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