Additionally added Documentation, Bug Report and Feature Request templates for better workflow.

Removed unnecessary comments, improved readability by adding comment into the variable.

Comments now Include small when inside a function or for loop and Big standard when outside of it, to further improve readability.

- Still Requires the reduction of repetition of code!

In the following addition it is required to keep " C_cpp_properties.json and tasks.json within the project as that is required for the library to work.

Having removed user based vscode additions it should work as intended!
Leaving instructions here:
Step 1: in  Msys2 terminal you write this  pacman -S mingw-w64-x86_64-gtk4
Step 2: pacman -S mingw-w64-x86_64-toolchain base-devel
After you got those fuckers
Step 3: you have a c project, and you need to generate those I'll most likely include in the commit so you dont have to fuck around with them unless you want to.
Image
Step 4: In main.c you want to try the code so copy paste
#include <gtk/gtk.h>

static void
print_hello (GtkWidget *widget,
             gpointer   data)
{
  g_print ("Hello World\n");
}

static void
activate (GtkApplication *app,
          gpointer        user_data)
{
  GtkWidget *window;
  GtkWidget *button;

  window = gtk_application_window_new (app);
  gtk_window_set_title (GTK_WINDOW (window), "Window");
  gtk_window_set_default_size (GTK_WINDOW (window), 200, 200);

  button = gtk_button_new_with_label ("Hello World");
  g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);
  gtk_window_set_child (GTK_WINDOW (window), button);

  gtk_window_present (GTK_WINDOW (window));
}

int
main (int    argc,
      char **argv)
{
  GtkApplication *app;
  int status;

  app = gtk_application_new ("org.gtk.example", G_APPLICATION_DEFAULT_FLAGS);
  g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
  status = g_application_run (G_APPLICATION (app), argc, argv);
  g_object_unref (app);

  return status;
}
Step 5: Open c_cpp_proprties.json
Step 6: you need this exact promt, make sure that the root directory is correct!!!!
{
  "configurations": [
      {
          "name": "Win32",
          "includePath": [
              "${workspaceFolder}/**",
              "C:/msys64/mingw64/include/gtk-4.0",
              "C:/msys64/mingw64/include/glib-2.0",
              "C:/msys64/mingw64/include/**",
              "C:/msys64/mingw64/lib/**"
          ],
          "defines": [
              "_DEBUG",
              "UNICODE",
              "_UNICODE"
          ],
          "windowsSdkVersion": "10.0.22000.0",
          "compilerPath": "C:/msys64/mingw64/bin/gcc.exe",

          "cppStandard": "c++17",
          "intelliSenseMode": "windows-gcc-x64"
      }
  ],
  "version": 4
}
Step 7: Make sure you add it into "edit environment settings"    You got to add it to the System Environment - >
Image
So you need to add the bin folder that you downloaded mingw64 to and the gtk4 will be there as well
Make sure that is right after program files otherwise won't work.
Image

all those ther and paths must be there for us to use it
Image
And that too, this is inside c_cpp_properties
Image

Step 8: you need task.json as well with this code
{
 "version": "2.0.0",
 "tasks": [
  {
   "type": "cppbuild",
   "label": "C/C++: gcc.exe build active file",
   "command": "C:/msys64/mingw64/bin/gcc.exe",
   "args": [

    "-IC:/msys64/mingw64/lib/graphene-1.0/include",
    "-mfpmath=sse",
    "-msse",
    "-msse2",

    "${file}",

    "-LC:/msys64/mingw64/lib",
    "-lgtk-4",
    "-lpangowin32-1.0",
    "-lpangocairo-1.0",

   ],
   "options": {
    "cwd": "C:/msys64/mingw64/bin"
   },
   "problemMatcher": [

   ],
   "group": "build",

  }
 ]
}

Refactored Codebase 2

.vscode Ignored Add your own!

… to ignore filtered images

added basic GTK+4.0 UI, and modified README.md

…compare filtered image & input image

…s to UI

Fixed (1) / add (2) filters, modified UI
