Dans le dossier partagé, vous trouverez différentes images.
|
||||||
|
\begin{enumerate}
|
||||||
|
\item Ouvrez-les puis classez-les en fonction de celles qui vous semble être les plus agréables à regarder.
|
||||||
|
\item Quels sont les caractéristiques des images qui vous ont permis de faire ce classement.

\begin{enumerate}

|
\item Lire le contenu et chercher la correspondance entre ce que vous voyez dans Notepad++ et sur Gimp (il faudra surement beaucoup zoomer).
|
||||||
|
\item Expliquer comment est construit une image bmp en noir et blanc.
|

|
\item Reproduire une image de l'exercice 2.

Dans cet exercice, nous allons faire la même chose que dans l'exercice précédent mais avec des images en nuances de gris.
|
||||||
|
\begin{enumerate}
|
||||||
|
\item Ouvrir avec Gimp puis avec notepad++, les images \texttt{gris.bmp}.
|
||||||
|
\item Lire le contenu et chercher la correspondance entre ce que vous voyez dans Notepad++ et sur Gimp (il faudra surement beaucoup zoomer).
|
||||||
|
\item Expliquer comment est construit une image bmp en noir et blanc.
|
||||||
|
\item Reproduire le plus fidèlement possible l'image ci-contre.

Suivant le nombre de bits utilisé, on peut définition plus ou moins de niveau de gris. C'est la \textbf{profondeur}.
|
||||||
|
\begin{itemize}
|
||||||
|
\item Avec 1 bit, on peut faire la différence entre 2 choses : 0 (blanc) ou 1 (noir).
|
||||||
|
\item Avec 2 bits, on peut faire la différence entre 4 choses : 00 (blanc) ou 01 (gris clair) ou 10 (gris foncé) ou 11 (noir).
|
||||||
|
\end{itemize}
|
||||||
|
\begin{enumerate}
|
||||||
|
\item Combien de "gris" différent peut-on faire avec 3 bits (on comptera le blanc et le noir comme des niveaux de gris)?
|
||||||
|
\item Avec 4 bits?
|
||||||
|
\item Avec 8 bits?
