This is a format for compact font storage in the OpenType system, allowing for the rasterization of text information. It differs from TrueType in its abilities to describe font symbols and with its font structure variation algorithm, depending on the change in size. CFF allows for increased screen clarity with high resolution, but this is not due to the font, but its rasterization.
This is a format for storing and presenting text information. It’s also referred to as CID 2 and is basically used for imaging and creating complex fonts in PDF. It’s based on the TrueType system, but allows for more precise adjustment and allows for refined writing due to a 16-bit structure that is very important when displaying Asian language symbols.
