Scalable Font
A scalable font is one in which each character’s dot pattern (bitmap)
is generated from a mathematical representation (or outline) of the
character. Scalable fonts eliminate the need to store many different
font sizes.
Point Size
Point size refers to the height of a proportionally spaced typeface. A
point is a unit of measure equal to
1
/
72
". Therefore, the larger the point
size, the larger the letter. The following example shows a character in
8, 10, 12, 24, and 36 point sizes:
A
B
C
D
E
Bitmapped Font
A bitmapped font is a one in which each
character is represented by a set of dot
patterns. Each font size requires a different
set of dot patterns.
Pitch
Pitch refers to the number of characters per horizontal inch (cpi) in a
monospaced typeface.Therefore, the larger the pitch, the smaller the
letter. For example, a ten-pitch typeface
prints ten characters per inch (or 10 cpi)
while a twelve-pitch typeface prints
twelve characters per inch (or 12 cpi).
The example shows ten-pitch and twelve-
pitch Courier.
