image_resizer

A simple c++ program that uses libpng and OpenCL to resize images.

Tools

• OS: Void linux
• Compiler: gcc
• Editor: neovim

Prerequisites

• make

• cmake

• pkg-config

• libpng: I grabbed the source code(version: 1.6.37) from it's official website. After downloading the source code, there's a nice and self-explanatory INSTALL document. To recap i ran the following commands to build libpng:

  cmake . -DCMAKE_INSTALL_PREFIX=/home/linarcx/libpng
  make
  make install
  

• OpenCl There's a libclc package in VoidLinux that i used it.

Build

git clone https://github.com/LinArcX/image_resizer
cd image_resizer
mkdir -p output/cmake output/debug output/release
cd output/cmake/
cmake -DCMAKE_BUILD_TYPE=Release ../..
make -j8

And finally run the program:

../release/image_resizer

Test

./output/x64/release/image_resizer -output ./assets/smaller.png -input ./assets/original.png -ratio 0.4 -quality 90 -algorithm "bicubic"
