Conversion de documents au format PDF
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 :
- Document Word (.doc, .rtf)
- Feuille Excel (.xls)
- Fichier texte (.txt)
- Fichier HTML (.html)
- Fichier PDF (.pdf)
- Images (.jpg, .gif, .tif, .png)
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 :
