Pixly - An image editor

Pixly is an image editor built in Compose Multiplatform and Rust that works on Windows, Linux and Android devices

• Compose makes the GUI
• Rust via zune-image deals with image manipulation operations.

Architecture

I've written on how the two apps work in my blog https://etemesi254.github.io/posts/Pixly-Image/

Motivation

I wanted a simple lightroom alternative that works on Linux.

Running

Android

If you just want to install the apk in your device, there is a release containing an .apk in the release page which you can install to test

If you want to run on Android, you need to set up your environment, see instructions on how to do that.

After setting up, load this project into your IDE and choose to run on a mobile device or an emulator

Building

For compiling the Rust dynamic library, see instructions on README on how to do that.

Android

You need to have an IDE capable of android Development, recommended and tested IDEs are Android-Studio and Intellij-Idea Ultimate.

You also need to have Android-SDK configured and Android-NDK configured if you are going to build the Rust binaries(see README on Rust on what to change)

Steps.

1. Clone this repo

   git clone https://github.com/etemesi254/Pixly

2. Load it in the IDE

3. Choose the device

4. Run composeApp on Android

5. Wait

6. Profit

Linux.

The main hurdle is getting the jvm/system loader to load the native library that contains the zune-image library bindings

We provide a compiled binding in the root directory, called libzune_jni_bindings , here are the options to load it

Move the library to a directory where the system loader looks

Here we move the compiled library to one of the directory the system loader looks into

• cd into the composeApp directory

cd ./composeApp

• copy the directory to a system directory

sudo cp ./libzune_jni_bindings.so /usr/lib/

• Then run

../gradlew desktopRun -DmainClass=MainKt --quiet

Set LD_LIBRARY_PATH

• We assume you are in the Pixly directory,

cd into the composeApp directory

cd ./composeApp

Add the current directory into the LD_LIBRARY_PATH, the $PWD shell will expand to the current directory

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PWD

Then inside composeApp directory, run

../gradlew desktopRun -DmainClass=MainKt --quiet

Windows

Assuming you are in the Pixly directory

• cd into composeApp directory

cd ./composeApp

• Run gradle desktop

../gradlew desktopRun -DmainClass=MainKt --quiet
