Description
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.
An ICO file is an image format used to store icons for Windows programs, files, and folders. It contains two bitmaps: 1) the AND bitmap - the image mask (which determines what part of the icon is transparent) and 2) the XOR bitmap - contains the icon which is mapped onto the image mask. ICO files can be modified to create custom icons.
