Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.nsmarinro:signatureview:0.1.2'
	}
	dependencies {
		implementation("com.github.nsmarinro:signatureview:0.1.2")
	}
	<dependency>
	    <groupId>com.github.nsmarinro</groupId>
	    <artifactId>signatureview</artifactId>
	    <version>0.1.2</version>
	</dependency>

                            
    libraryDependencies += "com.github.nsmarinro" % "signatureview" % "0.1.2"
        
        

                            
    :dependencies [[com.github.nsmarinro/signatureview "0.1.2"]]

Getting Started

This Library was developed for minSdkVersion 21 and targetSdkVersion 34 (for now)

Installing

Add it in your root build.gradle at the end of repositories

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

Add the dependency

dependencies {
	        implementation 'com.github.nsmarinro.SignatureView:librarySignature:0.1.2'
	}

## Usage

See app/src/main/java/nsmarinro/signatureview/ExampleActivity for more detailed code example of how to use the library.

  • Add signature View
  <nsmarinro.librarysignature.SignatureView
            android:id="@+id/signatureView"
            android:layout_width="match_parent"
            android:layout_height="300dp" />
  • Get signature data

signatureClear() - Clear Signature<br/> getSignatureBitmap() - Get Signature without bounding box and transparent background(final signature)<br/> getSignatureBitmap(true) - Get Signature with bounding boxes and white background (draw the bounding boxes detected)<br/> isSignature() - if something is already drawn or not<br/> setPathColor(color) - Set signature color<br/> setWidth(width) - Set the maximum width of the signature (the height is set proportionally of this width)<br/>

Note: setWidth(width) only take effect if the width of the signature is higher than this width
