Introduction

RxLowpoly serves as an enhancement over XLowPoly with various improvements. Here are some highlights:

• Fixes **out of memory** crashes by scaling images down in a lossless manner.
• Provides better quality results with a default point count of 4000, striking a balance between speed and quality.
• Offers wider input options, including Bitmap, File, Uri, or Drawable resources.
• Utilizes RxJava for background processing to minimize boilerplate code.

Installation

To get started with RxLowpoly, simply add the following dependency to your app module’s build.gradle file:

implementation 'com.zebrostudio.rxlowpoly:rxlowpoly:latest_version'

And just like that, you’re ready to start transforming your images!

Library Details

RxLowpoly utilizes the Java Native Interface (JNI) for performance, ensuring speed by employing 64-bit support, which is crucial for compliance with Google’s requirements. This library implements:

• The Sobel Operator for edge detection.
• Delaunay Triangulation to create the final low-poly effect.

What’s all this about?

Think of RxLowpoly as a skilled artist and your photo as a blank canvas. The Sobel Operator acts like a brush, tracing the edges, while Delaunay Triangulation creates a triangular mosaic on this canvas. As different shades are filled in, what results is a vibrant crystallized artwork!

Usage Examples

Using RxLowpoly is intuitive. Here are a few usage examples:

Asynchronous Call

RxLowpoly.with(context)
  .input(bitmap)
  .generateAsync()

Scaling the Image Down

RxLowpoly.with(context)
  .input(bitmap)
  .overrideScaling(downScalingFactor)
  .generateAsync()

Setting Quality

RxLowpoly.with(context)
  .input(inputUri)
  .quality(Quality.HIGH)
  .generateAsync()

Critical Analysis

Tests conducted on a Xiaomi Redmi Note 5 Pro show that the input type Bitmap offers the fastest processing. Higher quality levels slightly reduce speed but yield stunning textures. The default quality is thus set to HIGH for the best balance!
