El programa ofrecerá las capacidades y medios necesarios para realizar composiciones fotográficas a partir de diferentes archivos de imagen y tendrá como finalidad obtener una imagen que resulte de la correcta combinación de éstas. El objetivo es que los usuarios puedan realizar una composición fotográfica de forma básica e intuitiva que después será procesada de forma más compleja mediante un programa externo. La aplicación tendrá un enfoque a la edición digital de imagen desde los niveles más bajos, permitiendo a los usuarios más inexpertos expresar su creatividad e ideas en este campo. Por lo tanto, un aspecto clave será la experiencia de usuario basada en la sencillez y facilidad de uso de la propia herramienta. El trabajo a realizar comprende todas las fases en el desarrollo de un proyecto software de estas características, abarcando desde el extremo más teórico hasta el más práctico, y tanto en el ámbito más técnico como en el entorno de un usuario final. Para alcanzar los objetivos se hace uso de un amplio abanico de tecnologías, entre las que destacan los lenguajes de programación MySQL y Python, junto con las librerías convenientes, y el programa Eclipse como principal herramienta de desarrollo. PALABRAS CLAVE Desarrollo software, edición digital de imagen, Python, Eclipse, MySQL. TFG – Pablo Martín Junquera 7 Diseño y desarrollo de una aplicación de escritorio dedicada a la composición fotográfica ABSTRACT In this final project the design and development of a software application dedicated to the digital edition of images is proposed. The application will offer the abilities and means needed to create photographic compositions from different image files and will be destined to obtain a resulting image from the combination of these. Its goal is for the users to be able to carry out a photographic composition in a basic and intuitive way which will be processed in a more complex way by an external program afterwards. The application will be aimed at the digital edition of an image at its lower levels allowing the most inexperienced users to express their creativity and ideas in this field. Therefore, a key aspect of this application will be the user’s experience based in the simplicity and the ease in the use of this tool. The work to do includes every phase in the development of a software project of these characteristics, covering from the most theoretical aspects to the most practical ones, including the most technical issue as well as the final user environment. To achieve the goals, a wide variety of technologies have been used, among which the programming languages MySQL and Python stand out, along with the convenient libraries, and the application Eclipse as the main developing tool.

  • Staged Model-Driven Generators Shifting Responsibility for Code Emission to Embedded Metaprograms
    Staged Model-Driven Generators Shifting Responsibility for Code Emission to Embedded Metaprograms Yannis Lilis1, Anthony Savidis1, 2 and Yannis Valsamakis1 1Institute of Computer Science, FORTH, Heraklion, Crete, Greece 2Department of Computer Science, University of Crete, Crete, Greece Keywords: Model-Driven Engineering, Multistage Languages, Code Generation, Compile-Time Metaprogramming. Abstract: We focus on MDE tools generating source code, entire or partial, providing a basis for programmers to introduce custom system refinements and extensions. The latter may introduce two maintenance issues once code is freely edited: (i) if source tags are affected model reconstruction is broken; and (ii) code inserted without special tags is overwritten on regeneration. Additionally, little progress has been made in combining sources whose code originates from multiple generative tools. To address these issues we propose an alternative path. Instead of generating code MDE tools generate source fragments as abstract syntax trees (ASTs). Then, programmers deploy metaprogramming to manipulate, combine and insert code on-demand from ASTs with calls resembling macro invocations. The latter shifts responsibility for source code emission from MDE tools to embedded metaprograms and enables programmers control where the produced code is inserted and integrated. Moreover, it supports source regeneration and model reconstruction causing no maintenance issues since MDE tools produce non-editable ASTs. We validate our proposition with case studies involving a user-interface builder and a general purpose modeling tool. 1 INTRODUCTION driven tools and focuses on addressing the maintenance issues arising from code generation. In general, Model-Driven Engineering (MDE) We continue elaborating on parameters of the involves tools, models, processes, methods and problem and then brief the key contributions of our algorithms addressing the demanding problem of work to address this issue.

  • Introduction to Eclipse and Pydev Fall 2021 Page 1 of 6
    Introduction to Eclipse and PyDev Fall 2021 Page 1 of 6 Introduction to Eclipse and PyDev We will be using Eclipse PyDev plugin in this course to create and run Python programs. Eclipse is a platform that can be used for application development tasks using different languages, including Java and Python. A separate handout describes how to install Eclipse and its Python plugin - PyDev. This handout will take you through the process of creating and running a Python program. Specifying the Eclipse workspace When you start Eclipse, you will be asked to specify the directory in which to store your projects. By default, on Windows, it creates a folder called eclipse-workspace in your personal folder Use this directory or another of your choice. To switch the workspace to a different folder, after starting Eclipse, go to File > Switch Workspace and select the desired folder. Creating a new PyDev project To create and run a Python program in Eclipse, you must form a project for it: 1. Create a new PyDev Project by selecting File > New > Project>PyDev > PyDev Project. This will open the PyDev Project dialog window (see Error! Reference source not found.) 2. In the dialog window: • Enter a project name of your choice into the Project name field. 3. In the PyDev Project dialog box ( Figure 1), make sure the right interpreter is selected (To make sure python version 3 is selected, click on Configure the interpreter not listed link verifying that the selected interpreter’s location should be within anaconda3 installation, i.e. mention anaconda3 in the path (Figure 2) ) Click on Finish.

Καθηγητής ΘΕΣΣΑΛΟΝΙΚΗ 2015 ΠΕΡΙΛΗΨΗ Π ΕΡΙΛΗΨΗ Αντικείμενο της παρούσας εργασίας είναι η παιχνιδοκεντρική μάθηση και η ανάπτυξη ενός εκπαιδευτικού παιχνιδιού. Με την ανάπτυξη της τεχνολογίας στις μέρες μας, η διαδικασία της εκπαίδευσης και της μάθησης έχουν αλλάξει δραματικά. Η μάθηση δεν είναι πλέον μια κλασσική διαδικασία που στηρίζεται μόνο στα βιβλία. Η εργασία ασχολείται με την παιχνιδοκεντρική μάθηση και τη χρήση των παιχνιδιών σε αυτή τη διαδικασία, ενώ περιγράφεται και η ανάπτυξη ενός τέτοιου εκπαιδευτικού παιχνιδιού. Στο πρώτο μέρος περιγράφεται η έννοια της παιχνιδοκεντρικής μάθησης, εκείνης της διαδικασίας μάθησης που χρησιμοποιεί ως μηχανισμό το παιχνίδι. Επίσης περιγράφονται οι διάφορες κατηγορίες εκπαιδευτικών παιχνιδιών. Στο δεύτερο μέρος γίνεται αναφορά στη γλώσσα Python, το μοντέλο εκτέλεσής της και την ιστορία της. Έπειτα γίνεται αναφορά στη βιβλιοθήκη Pygame και στα εργαλεία που χρησιμοποιήθηκαν στην ανάπτυξη του παιχνιδιού. Στο τρίτο μέρος της εργασίας αναλύεται η υλοποίηση ενός εκπαιδευτικού ψηφιακού παιχνιδιού με τίτλο «Binary Droids», υλοποιημένο σε Python, με χρήση της Pygame. Το παιχνίδι έχει σκοπό την εκμάθηση μιας βασικής έννοιας της Πληροφορικής, αυτήν του δυαδικού συστήματος αρίθμησης, και της μετατροπής αριθμών από το δυαδικό σύστημα στο γνωστό σε όλους δεκαδικό. Το παιχνίδι χρησιμοποιεί επιβραβεύσεις και ποινές, όταν ο χρήστης εκτελεί τις μετατροπές των αριθμών σωστά και όταν τις εκτελεί λάθος, αντίστοιχα. Όσο ο χρήστης επιβραβεύεται για τις επιδόσεις του στο παιχνίδι, ανεβαίνει επίπεδα και συνεπώς αυξάνεται και η δυσκολία.
