Curve quadratiche di Bézier

Per le curve quadratiche di Bézier si possono costruire punti intermedi Q₀ e Q₁ al variare di t da 0 a 1:

• Il punto Q₀ varia da P₀ to P₁ e descrive una curva lineare di Bézier.
• Il punto Q₁ varia da P₁ to P₂ e descrive una curva lineare di Bézier.
• Il punto B(t) varia da Q₀ to Q₁ e descrive una curva quadratica di Bézier.

Curve di Bézier cubiche

Per curve di ordine superiore è necessario un maggior numero di punti intermedi.

Per una curva cubica si possono costruire i punti Q₀, Q₁ e Q₂ che descrivono una curva Bézier lineare, e i punti R₀ e R₁ che descrivono una curva Bézier quadratica:

Immagini scannerizzate

Immagini che hanno tutte lo stesso background e che sembrano scannerizzate da un opuscolo fatto in cartoncino rugoso: si tratta di un tipico effetto di una cattiva scansione di foto presenti su carta stampata dovuto alla differenza tra la "frequenza" della scansione e quella della stampa (di solito evitabile tramite opzioni del dirver di scansione).
