+# Projet TDS MASI 4
+---
+# Ce qui a changé
+
+## Fonctionnalité
+Certaines fonctionnalités ont été déplacées ou légérement adaptée afin de les rendre 
+plus facile à prendre en main
+
+---
+
+### Réorganisation des menus
+Certains items du menu tels que le chargement et la création des image, 
+les fonctionnalités de dessin et l'affichage des transformées de Fourier ont été rémaniés.
+---
+
+### Chargement et création des images
+Désormais les images sont automatiquement chargée en format RGB. 
+Leur réprésentation en niveaux de gris est gardée en mémoire à chaque 
+modification de l'image et peut-être utilisée dès que nécessaire.
+
+#### Exemple 
+```java
+//Crée une image blanche de 512 pixels par 512 pixels
+Image image = new Image(255,255,255, 512,512);
+
+//Crée une copie de l'image en récupérant son équivalent en niveaus de gris
+GrayScaleMatrix = image.toGrayScale();
+```
+
+---
+
+### Affichage des transformées de fourier
+
+Le module, la phase, la partie réelle et la partie imaginaire sont maintenant 
+régroupés dans une seule et même fenêtre. L'affichage des transformées de plusieurs 
+images différentes à travers différentes fenêtres reste possible.
+
+![fourier](./menu_fourier.png)
+---
+
+## Architecture
+C'est ici que la majorité des changements ont eus lieu. 
+Une architecture et des patterns modernes ont remplacé la majorité 
+de la base de code précédente. 
+
+### MVP
+Le programme utilise maintenant un design pattern architectural 
+Model-View-Presenter afin de séparer au mieux les responsabilités 
+des différentes couches et d'imposer un flux d'éxecution strict 
+tel que décrit comme suit :
+
+- View : Réceptionne les événements utilisateur et gère l'état visuel de la fenêtre
+- Presenter : Couche d'orchestration entre la vue et la logique métier. Possède un accès aux données locales à la vue courante.
+- Services : Couche tampons faisant le lien entre les presenters, l'infrastructure et la couche domaine. Possède un accès à l'état global de l'application
+- Domaine : Contient la logique métier de l'application. Doit rester totalement agnostique de toute dépendance technologique
+- Infrastructure : Couche contenant un accès à des ressources externes telles que le système de fichier de la machine hôte
+![architecture](./architecture.png)
+
+### Gestion d'état
+La gestion d'état a été remaniée. Plusieurs composants d'état sont maintenant disponabible  dans le package *app.state* :
+- Classe abstraite *State* : Classe parent donnant une structure à chaque classe d'état
+- Etat global du programme : Représenté par la classe *AppState*. Cet classe est déclarée comme étant un singleton dans le conteneur Guava
+- Etat local d'une vue : Representé par toutes les autres classes disponibles dans le package. Ne devrait pas être un singleton
+
+### Injection de dépendances
+Le programme utilise maintenant le conteneur d'injection de dépendance de Google, Guava.
+Cet ajout permet d'isoler la logique d'instanciation des différents composants lors de l'éxecution. 
+La logique de navigation entre les différentes fenêtres s'en retrouve facilitée.
+Toutes les dépendances sont enregistrées dans la classe *AppModule* au sein du package *app*
+
+### Logique de navigation
+L'injection de dépendance précédement expliquée a permis d'isoler la logique de navigation.
+Désormais, pour naviguer entre différentes vue, il suffit de créer une méthode au sein de 
+la classe SwingNavigator, d'injecter l'interface INavigator dans une Presenter et d'appeler la méthode nouvellement créée.
+
+Un exemple de fonctionnement est déjà fourni dans la classe SwingNavigator et peut-être facilement retracé en trouvant
+les usages de la méthode *showFourier()* avec un IDE moderne.
+
+#### Note importante
+Toutes les vues doivent être enregistrée en tant que dépendance au sein du conteneur Guava. 
+Pour ce faire, différents exemples sont déjà implémenté dans la classe *AppModule*. 
+Cet ajout aura pour conséquence de donner accès à un objet ``Provider<T>`` (où T est le type de la dépendance enregistrée)
+qui pourra être injecté dans la classe SwingNavigator.
+
+Appeler la méthode ``Provider<T>.get()`` aura pour conséquence d'instancier la dépendance désirée, dans notre cas, 
+une potentielle vue qui pourra ensuite être affichée.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/master/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
