Sketch 
An image manipulation library for Kotlin.
Sketch doesn’t require any external installation like OpenCV or OCR and can be used right away. It’s actually a
zero-dependency library designed for simplicity that wraps the Java AWT BufferedImage. The library provides an
asynchronous interface for all image operations.
Requirements
- Java 8+
Installation
The library is intended to be published to Maven Central.
In the meantime, it can be installed locally:
./gradlew publishToMavenLocal
Add the library as a dependency to your project:
dependencies {
implementation("io.github.reugn:sketch:0.1.0")
}
