Stato dello sviluppo di PDF Clown.

Questa tavola descrive analiticamente lo stato d'implementazione della specifica PDF 1.6 da parte di PDF Clown.

Note

Legenda della tabella:

colonna 'Section': riferimento a una corrispondente sezione della specifica;
colonna 'Implemented': lista delle porzioni implementate di ogni sezione;
colonna '%': stima del progresso corrente d'implementazione di ogni sezione;
colonna 'To implement': lista delle porzioni ancora da implementare di ogni sezione.

I numeri racchiusi tra parentesi quadre (ad esempio "[2]") rappresentano il livello di priorità associato alla funzionalità da implementare, ossia la relativa importanza della funzionalità, da cui la probabilità per essa di essere implementata. Il livello di priorità spazia da 0 (minimo) a 5 (massimo).
