mm2pxl da mm a pixel
Questa volta ci accingiamo a calcolare le dimensioni in pixel a partire dal formato di stampa (in questo caso ci rifaremo allo standard ISO 216: Writing paper and certain classes of printed matter – Trimmed sizes – A and B series). Per fare questo partiremo dalle dimensioni dei singoli formati, le divideremo per 25.4 (un pollice espresso in millimetri) e le moltiplicheremo per i dpi richiesti.
