What environment

Guide for following setup:

• Oracle VM VirtualBox Ubuntu 18.04.6
• IDE NetBeans
• Libs: Magick++, GTK+

Tips

• You can setup drag-drop feature and any other tools you wanted by your own need. Skip stages in instalation guide that you an't gona need it.
• Note you also need a 'pkg-config' installed.

Setup gide

Stage 1: Updloading libraries and compilator

• You need to update use following termanal comands:

$ sudo apt-get update
$ sudo apt-get upgrade

• Upload libraries. First command installs compilator next command - used ligraries:

$ sudo apt-get install build-essential
$ sudo apt-get install libgtk-3-dev g++ 
$ sudo apt-get install libmagick++-dev

Stage 2: Installing IDE NetBeans

To install NetBeans first of all you need to install JDK:

$ sudo apt-get install default-jdk

To instal NetBeans I use 'snap'. You will get last stable version with following command:

$ sudo snap install netbeans --classic

Stage 3: Installing IDE NetBeans

Instalation of base kit of NetBeans(to have possibility work with C/C++ you need to install plugins):

$ sudo snap install netbeans --classic

Stage 3: Cloning repo

Choose folder for git repo. Clone git repo:

$ git clone https://<link to git repo>

Stage 4: Setuping IDE, run the project

1. You need to instal plugins for C/C++. Here you can follow this guide:

2. In repo I prepared several image and watermark samples. To get it ready to use goto root directory of project and unzip file samples.tar.gz. Type following comand:

$ tar -xzvf pic-samples.tar.gz

3. Open repo as a project in NetBeans "File"->"Open Project..." find the roor directory and select it.

4. Configure compilator options:

Select "Project Poperties", in tab "C++ Compilator" -> "Additional options" set following options (single quotes in parameters are important):

`pkg-config --cflags gtk+-3.0` -std=c++11 `Magick++-config --cxxflags --cppflags`

In option "Include Directories" you need point path to libraries. In my case I have following paths:

/usr/include/Magick++ 
/usr/include/ImageMagick-6/ 

And in option "Include Headers":

/usr/include/Magick++/Include.h 

To find and add required libs you can use:

$ cd :/
$ find . -name lib-name

In tab "Linker" -> "Additional options" set following options (single quotes in parameters are important):

`pkg-config --libs gtk+-3.0` `Magick++-config --ldflags --libs`

How to use

The application is simple. It consist of 5 buttons. Each of the first three buttons represents process of uploading, processing and saving processed image. I advice to use button "Load image to view" to check up processing results instantly in application.

The operations hardcoded to simplify input process. The coveting watermark also hardcoded. And you can change the watermark by replacing file: gtk-master/pic-samples/watermark.png. Each watermark normalized into size of 200x100, so you can apload picture with any size.
