Can I use the HVDOSFNT.COM program in a
Windows DOS Box/Terminal?
You can
run HVDOSFNT
in both Windows' DOS boxes and
CMD.EXE
Windows Terminal modes. However, the memory resident HVDOSFNT
is only used in Full-screen
modes. To have access to the HVFont
in Windowed
and Full-screen
modes you must also install the HVDOSBox
font for Windows.
HVDOSFNT.COM
can still be run from the command line with the /A
switch to display all 256
characters in the extended ASCII PC8 character set.

What Fonts will Windows use in DOS
Boxes (and NT Terminal Modes)?
A DOS
box - or Windows Terminal - in Full-screen
mode is just like
MS-DOS. It uses the resident VGA
hardware font - or a DOS
software replacement like HVDOSFNT.COM.
When an NT Terminal or DOS
box is in Windowed
mode, Windows
must emulate the DOS
VGA hardware font with a monospaced
Windows
font. It can use raster
or vector (Truetype)
fonts for this emulation.
The Truetype
font is normally Lucida Console - provided in the file
LUCON.TTF.
The raster
font is the Terminal
font - from the file VGAOEM.FON
or 8514OEM.FON.
Raster
fonts produce clearer text than vector
fonts. You can add to the very limited set of Terminal
font sizes provided by Windows
by installing additional Terminal
fonts.

Where/what is the Windows' Fonts Directory?
The Fonts directory is a hidden subdirectory under the main
Windows
directory. It is where Windows
keeps its installed fonts. (For example, if the Windows
directory is D:\WINNT the
Fonts directory is
D:\WINNT\Fonts).
The Fonts Directory will be visible in
Windows' Explorer
provided
Explorer
is configured to show Hidden files. (From the
View menu, select
Folder Options,
View tab,
Files and
Folders, Hidden
files, and check the
Show all files radio button.) To see
Filenames as well as
Fontnames - they are
not the same - select
Details view in
Explorer.
The Fonts directory is hidden because it is not intended that users should
directly manipulate files in this directory.
Windows
actually opens the font files when it starts and keeps them open until it closes down. You will not be
allowed to directly manipulate (delete, replace,
rename, etc.) these files
while Windows
is running. To do so you must exit from Windows
to MS-DOS mode
- or boot the machine from an MS-DOS system disk.
Installing and removing fonts is best done through the
Windows
Control Panel,
Fonts
applet.

What are all these FON files in the Fonts Directory?
Files with a FON extension are
raster
("bitmap") font files.
Windows uses both
raster and
vector
(scalable) fonts. The
vector fonts are
typically Truetype
fonts contained in files with a TTF extension.
Some FON files are used by
Windows' systems functions and must
not be removed.

What is a Monospaced Font?
A
monospaced font is a "fixed
width"
or
"fixed
pitch" font.
Every character in the symbol set has the same width. Monospaced fonts are used
in MS-DOS,
Windows' DOS
boxes, Windows'
Terminal
mode, code editors and similar applications. Fixed
pitch text can take up
more width than proportional
text - and is not a
good choice for large blocks of pure text. However, it is easier to work with in
applications where columns of text should - or must - "line up".

What is a Raster Font?
A raster
font is another
name for a bitmapped
font. (Windows
NT/2000/XP/Vista tends to use the
term "raster
font", while
other Windows'
versions - and most other systems - refer to "bitmapped
fonts".)
A bitmapped
font represents
each character glyph using a bitmap array. As the logical
size of the bitmap is
fixed, its physical size
(inches WxD)
on a screen - or printer - will depend upon the resolution
(dots - or "pixels" - per inch) of the device.
Raster fonts
are therefore less "efficient" than scalar
fonts - they need separate
bitmap sets for each
and every font size.
However, the quality of the hand crafted glyphs is typically much better
than that produced by scaling algorithms - especially at small point sizes.
They are always preferred in situations where text clarity is critical and
screen "space" is at a premium.

What is a Truetype Font?
A Truetype
font is a scalar
- or scalable - font.
A scalable font, unlike a
raster
font, is defined using mathematical
vectors. This enables a
Font manager
to render a range of sizes from the same definition.

Why is small text so jagged?
Screen resolution
is much "coarser"
than printer
resolution. Even a
large, high resolution,
monitor cannot compete
with printed output. For example, a 17" monitor at
XGA (1024x768) resolution produces output at
about 78 pixels - or dots - per inch. Laser
printers produce 300 to
1200 dots per
inch!
The pixel representation of the
shape of small characters and figures has to be compromised. While skilled type
designers can minimise the impact of these compromises - especially with
individually designed raster glyphs - there are definite limits to the
legibility of very small screen fonts.

How do I install a Windows' Font?
Windows'
fonts are best installed using the Windows
Control Panel,
Fonts
applet. Save the new font file(s) in a working directory, from the Start
menu, select Control
Panel, then Fonts.
Select File
menu, Install
New Font, and
navigate to the working directory where the font file is located. Select the new
font file(s) and they will be copied to the Windows'
Fonts
directory and
be made available to applications.

How do I change the Screen Display setting from
Small to Large Fonts?
Right Click on a blank area of
the Windows'
desktop,
Select Properties
and then the Settings
tab. Select Advanced
and - in the Font
size combo box -
select Large
Fonts. Click OK
to save and apply the change.

What is "greeked" text?
"Greeked"
text is sometimes used to describe "garbage" phrases entered into an
application to check layouts and screen designs. For example:-
Hanc ego cum teneam sententiam, quid est cur verear, ne ad eam non possim accommodare Torquatos nostros? quos tu paulo ante cum memoriter, tum etiam erga nos amice et benivole collegisti, nec me tamen laudandis maioribus meis corrupisti nec
segniorem ad respondendum reddidisti. quorum facta quem ad modum, quaeso, interpretaris? sicine eos censes aut in armatum hostem impetum fecisse aut in liberos atque in sanguinem suum tam crudelis fuisse, nihil ut de utilitatibus, nihil ut de commodis suis cogitarent? at id ne ferae quidem faciunt, ut ita
ruant itaque turbent, ut earum motus et impetus quo pertineant non intellegamus, tu tam egregios viros censes tantas res gessisse sine causa?
More commonly, it refers to an approximation of
the appearance of text and figures on a screen. "Greeking" is often
used in an application's preview mode when the monitor resolution is too low to
properly display very small character glyphs.
