Content-Aware Resizing (CAR) - is a cross-platform bilingual (C#/Java) implementation of the Seam carving algorithm.

The Content-Aware Resizing algorithm allows resizing images (jpeg, png and others) while preserving the significant parts of the image and maintaining their proportions.

The project consists of several sub-projects, each targeted to a specific environment.

The latest binaries (dll file) can be downloaded from http://github.com/OlegZhukov/CAR/releases/download/v2.0/CAR.Paint.NET.zip.

Just copy the CAR.Paint.NET.dll library to the Effects folder in the Paint.NET directory (usually C:\Program Files\paint.net\).

The corresponding VS project is located in the *CS\CAR.Paint.NET* directory. Before compiling it reroute (if needed) the project references pointing to Paint.NET dll's.

The latest binaries can be downloaded from http://github.com/OlegZhukov/CAR/releases/download/v1.5/CAR.Win.zip.

To resize Image.png to 50% of its current width, type:

CAR.exe Image.png --width=50%

To see the usage prompt, just run CAR.exe without arguments.

Compiling CAR.exe from sources is as easy as opening CS/CAR.sln solution in Visual Studio and running the compilation.

However, in order to compile and run tests (CAR.Test project) the NuGet plug-in for Visual Studio is required. Once installed, it will automatically resolve dependencies and download necessary assemblies. You will also need to configure your favorite test runner to run the NUnit tests found in CAR.Test.dll.

Again, compiling CAR.exe is fairly straightforward in MonoDevelop just like in Visual Studio.

Precompiled version of CAR.exe for Linux (Ubuntu) is available at http://github.com/OlegZhukov/CAR/releases/download/v1.5/CAR.Mono.Linux.zip.

As for the tests (CAR.Test project), MonoDevelop will need to locate the NUnit and SpecFlow assemblies. Therefore you might need to add the corresponding .pc files to your /usr/lib/pkgconfig/ directory.

The latest binaries (class files and necessary jar libraries) can be downloaded from http://github.com/OlegZhukov/CAR/releases/download/v1.5/CAR.Java.class.zip.

To resize Image.png to 50% of its current width, navigate to the directory where you extracted the downloaded zip file and type (in Windows):

java -cp "./;./lib/stdlib-package.jar" com.OlegZhukov.CAR.CAR Image.png --width=50%

To see the usage prompt, just omit the arguments afer "CAR":

java -cp "./;./lib/stdlib-package.jar" com.OlegZhukov.CAR.CAR

In Linux use : instead of ;:

java -cp "./:./lib/stdlib-package.jar" com.OlegZhukov.CAR.CAR Image.png --width=50%
java -cp "./:./lib/stdlib-package.jar" com.OlegZhukov.CAR.CAR

The simplest way to compile the Java CAR project is to it using the Eclipse IDE. Just open the Eclipse project in Java folder and run the compilation.
