What are TrueType fonts? If you are sitting at a Windows or Macintosh computer right now, then you are looking at a TrueType font as you read this!  Fonts  are the different styles of typefaces used by a computer to display text. If you are like most people, you are probably looking at text in many different sizes and you may even want to print out a document.

If you made the font larger or smaller than it was intended to be, it looked horrible. And printed text was almost always very jagged looking. In the late 1980s,  Adobe  introduced its  Type 1  fonts based on  vector  graphics. Unlike bitmapped fonts, vector fonts could be made larger or smaller ( scaling ) and still look good. Adobe also developed a printing language called  Po...

We most generally encounter man made colour in two fundamentally differing ways:  On electronic display screens (computers, phones, TVs, etc) where the colour is the result of projected or emitted light In printed forms, where the colour is a result of pigments, dyes or whatever else is placed on the printing surface (substrate) RGB colour RGB colour is what you are most likely looking at right now (unless you have printed this page on paper!). RGB colour is made up of Red, Blue, and Green light. Where colours mix, their waveforms merge to create secondary colours. Computers generally display colour onscreen using a pallette o...
