Edition :Conversion de documents au format PDF

Modifier l'intitulé' :

Le but de ce projet est de générer un fichier PDF incluant plusieurs documents de types différents. Nous allons gérer au moins les types suivants :<ul><li>Document Word (.doc, .rtf)</li><li>Feuille Excel (.xls)</li><li>Fichier texte (.txt)</li><li>Fichier HTML (.html)</li><li>Fichier PDF (.pdf)</li><li>Images (.jpg, .gif, .tif, .png) </li></ul>Les documents devront être mis à la suite dans un unique fichier PDF, il faudra aussi permettre a l'application de générer ses propres fichiers pdf avec des données internes.Nous allons utiliser les logiciels suivants : <ul><li>Framework .NET 2.0 <a href="http://www.microsoft.com/downloads/details.aspx?FamilyID=0856eacb-4362-4b0d-8edd-aab15c5e04f5&displaylang=fr">[Site]</a> </li><li>iTextSharp 4.1.2 <a href="http://sourceforge.net/projects/itextsharp/">[Site]</a> </li><li>PDFCreator 0.96 <a href="http://www.pdfforge.org/products/pdfcreator">[Site]</a></li><li>Microsoft Office</li></ul> Classe de conversion PDF      using System;
