✨ Features

• 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.

🆕 What's New in Version 3.0.0?

• 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.

📦 Setup

Gradle Kotlin DSL (Multiplatform)

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

sourceSets {
    
    val commonMain by getting {
        
        dependencies {
            
            // ...
            
            implementation("io.github.stoyan-vuchev:squircle-shape:<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 = "io.github.stoyan-vuchev", name = "squircle-shape", version.ref = "squircle-shape" }

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

sourceSets {

  val commonMain by getting {

    dependencies {

      // ...

      implementation(libs.squircle.shape)

    }

  }

  // ...

}

2. Sync and rebuild the project. 🔄️🔨✅

🚀 Usage

1. Using Squircle Shapes with MaterialTheme

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")
    }

    // ...

}

2. Using Squircle Shapes separately

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
)

3. Draw a Squircle on Canvas

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
        )
    
    }
)
