A Compose Multiplatform library providing customizable Squircle shapes for UI components.

• Customizable Squircle Shapes: Create UI shapes that smoothly transition between squares and circles.
• Integration with MaterialTheme: Use squircle shapes directly in Jetpack Compose themes.
• Corner Smoothing: Fine-tune the smoothness of corners for a delightful design.
• Multiplatform Support: Available for Android, iOS, Desktop (JVM), and Web (WasmJS).
• Canvas Drawing: Easily draw squircle shapes on canvases with drawSquircle().

• Seamless MaterialTheme Integration:
  SquircleBasedShape now extends CornerBasedShape, allowing you to use it directly in androidx.compose.material3.Shapes.

• Corner Smoothing Support:
  Added the cornerSmoothing parameter for effortless corner smoothing without extra overhead.

• RTL Layout Support:
  Fully compatible with both LayoutDirection.Ltr and LayoutDirection.Rtl, ensuring proper corner mapping.

• Performance Enhancements:
  Optimized corner clamping logic for improved rendering performance.

• Kotlin: 2.0.21
• Compose: 1.7.1

• Kotlin: 2.0.21
• Jetpack Compose: 1.7.1
• Minimum SDK: 23
• Compile SDK: 35

1. Add the dependency in your shared module's build.gradle.kts:

sourceSets {
	commonMain.dependencies{
 	 implementation("com.composevisualeditor.apoloapps:squircle-shape:<version>")
	}
}

2. Sync and rebuild the project. 🔄️🔨✅

• 1. Add the Squircle Shape dependency in your module build.gradle.kts file.
• Latest version:

dependencies {
    implementation("com.composevisualeditor.apoloapps:cve-squircle-shape-android:<version>")

}

• Or if you're using a version catalog (e.g. libs.versions.toml), declare it in the catalog instead.

[versions]
squircle-shape = "<version>"

[libraries]


squircle-shape = { group = "com.composevisualeditor.apoloapps", name = "cve-squircle-shape-android", version.ref = "squircle-shape" }

• Then include the dependency in your module build.gradle.kts file.

dependencies {

  // ...

  implementation(libs.squircle.shape)

}

2. Sync and rebuild the project. 🔄️🔨✅

Define squircle shapes in your theme to use them consistently across your app:

val shapes = Shapes(
    small = SquircleShape(radius = 16.dp, cornerSmoothing = CornerSmoothing.Medium),
    medium = SquircleShape(radius = 32.dp, cornerSmoothing = CornerSmoothing.Medium),
    large = SquircleShape(percent = 100, cornerSmoothing = CornerSmoothing.Medium)
)

MaterialTheme(
    shapes = shapes
) {

    // ...

    Button(
        onClick = { /* Action */ },
        shape = MaterialTheme.shapes.large // Clipped to the provided `large` material theme shape.
    ) {
        Text(text = "Full Squircle")
    }

    // ...

}

Clip UI components separately by using a SquircleShape() function.

Image(
    modifier = Modifier
        .size(128.dp)
        .clip(
            shape = SquircleShape(
                percent = 100,
                cornerSmoothing = CornerSmoothing.Medium
            )
        ), // Clipped to a fully rounded squircle shape.
    painter = painterResource(R.drawable.mlbb_novaria),
    contentDescription = "An image of Novaria.",
    contentScale = ContentScale.Crop
)

You can customize the radii for all corners, or for each corner independently. Supported corner values are:

• Int for percent-based corner radius in range 0..100
• Float for pixel-based corner radius e.g. 50f
• Dp for density pixel-based corner radius e.g. 16.dp

// Single-corner percent-based radius implementation.
SquircleShape(
    percent = 100,
    cornerSmoothing = .6f
)

// Single-corner pixel-based radius implementation.
SquircleShape(
    radius = 32f,
    cornerSmoothing = .6f
)

// Single-corner density pixel-based radius implementation.
SquircleShape(
    radius = 32.dp,
    cornerSmoothing = .6f
)

// Multi-corner percent-based radius implementation.
SquircleShape(
    topStart = 25,
    topEnd = 5,
    bottomStart = 25,
    bottomEnd = 5,
    cornerSmoothing = .6f
)

// Multi-corner pixel-based radius implementation.
SquircleShape(
    topStart = 32f,
    topEnd = 8f,
    bottomStart = 32f,
    bottomEnd = 8f,
    cornerSmoothing = .6f
)

// Multi-corner density pixel-based radius implementation.
SquircleShape(
    topStart = 32.dp,
    topEnd = 8.dp,
    bottomStart = 32.dp,
    bottomEnd = 8.dp,
    cornerSmoothing = .6f
)

You can draw squircle shapes on a canvas for custom graphics.

Note: currently drawSquircle only accepts pixel-based values for each corner:

Canvas(
  modifier = Modifier.size(150.dp),
  onDraw = {

    drawSquircle(
      color = Color.Blue,
      topLeft = Offset.Zero,
      size = this.size,
      topLeftCorner = 32.dp.toPx(),
      topRightCorner = 8.dp.toPx(),
      bottomRightCorner = 32.dp.toPx(),
      bottomLeftCorner = 8.dp.toPx(),
      cornerSmoothing = .6f
    )

  }
)
