These graphics displays generally came with a set of fonts built-in when IDL asked the device to display characters in a built-in font, it was making a request to the hardware to display those characters.Īs computer displays have become more sophisticated, the concept of fonts provided “by the hardware” has expanded to include fonts provided by the computer’s operating system, or by font-management software. This is because in the early days of IDL, computer displays were either text-only terminals or dedicated graphics display devices such as plotters or Tektronix graphics terminals. In past releases of IDL, we have used the term “ hardware fonts” extensively to discuss these types of fonts. Device, or hardware, fonts are fonts that are provided directly by your system’s hardware or by software other than IDL.
