Building RawScaler (Windows)

> git clone https://gitlab.com/eric.liu/RawScaler.git
> cd $RawScaler_root/script
> build_win.cmd
> cd $RawScaler_root
> mkdir out

Configuring RawScaler (Windows)

> Edit build_win.cmd
> Set DOpenCV_Enable ON/OFF 

Linux Setup

Building RawScaler (Linux)

> git clone https://gitlab.com/eric.liu/RawScaler.git
> cd $RawScaler_root
> sh build.sh
> mkdir out

Configuring RawScaler

> Edit build_win.sh
> Set DOpenCV_Enable ON/OFF 

OpenCV_Enable=ON

1. If opencv enable , the resullt image will show on GUI

OpenCV_Enable=OFF

1. The input file muse be bitmap file (.bmp)

Demo

Windows Run

> cd $RawScaler_root
> script\build\Release\RawScaler.exe data\kodim19.bmp 300 300

RawScaler.exe file output-width output-height

1. arg can be null , the output file are stored in $RawScaler_root\out
   

Linux Run

> cd $RawScaler_root
> ./RawScaler data/kodim19.bmp 300 300
