pxl2mm da pixel a mm
Per passare dall'immagine in pixel alla dimensione di stampa in millimetri è necessario avere qualche nozione in più. Sul concetto di pixel non credo ci sia nulla da dire, almeno spero; il valore DPI indica quanti punti per pollice (dots per inch) saranno stampati. Da questo possiamo dedurre una formula: prendiamo i pixel della nostra immagine, dividiamoli per il valore DPI e il risultato lo moltiplichiamo per 2.54 (e otterremo il valore in centimetri) o 25.4 (per avere il valore in millimetri).
