What's the difference between open type and true type?

Answer 1

The different type fonts correlate to different types of printer's and monitor's capabilities. It is a difficult concept to really understand unless it is correlated to a specific piece of hardware. For example: old-fashioned daisy-wheel or chain printers required every character to be the same height and width while new-fangled laser printers can alter height and width almost anyway you want.

Answer 2

True type fonts use vector graphics.
Bitmap fonts use pixel based graphics.

If you greatly enlarge a pixel based font it will appear rough.
If you greatly enlarge a truetype font it will appear smooth.

"TrueType is an outline font standard originally developed by Apple Computer in the late 1980s as a competitor to Adobe's Type 1 fonts used in PostScript. The primary strength of TrueType was originally that it offered font developers a high degree of control over precisely how their fonts are displayed, right down to particular pixels, at various font heights. (With widely varying rendering technologies in use today, pixel-level control is no longer certain.)"

If they are all in nice, neat columns, do the following. Go to the BOTTOM entry, and click-drag a box upward. Pull the cursor up and it will zoom off the screen. When it hits the top, pull it left/right over the columns you need to sort. Then sort as normal! Very easy :)
