ComposeSignature

✍️ A Jetpack Compose library for capturing and exporting signatures as Bitmap with customizable options. Perfect for electronic signature, legal documents and more.

Step 1. Add the JitPack repository to your settings.gradle file

    allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

Step 2. Add the dependency

    dependencies {
        implementation 'com.github.JoelKanyi:ComposeSignature:1.0.0'
    }

Usage

Add the ComposeSignature composable into your project and customize it according to your needs:

var imageBitmap: ImageBitmap? by remember {
    mutableStateOf(null)
}

ComposeSignature(
    modifier = Modifier
        .fillMaxWidth()
        .padding(16.dp),
    signaturePadColor = Color(0xFFEEEEEE),
    signaturePadHeight = 400.dp,
    signatureColor = Color.Black,
    signatureThickness = 10f,
    onComplete = { signatureBitmap ->
        imageBitmap = signatureBitmap.asImageBitmap()
    },
    onClear = {
        imageBitmap = null
    }
