Hello, and welcome to the GFONTS version 3.0 demo.
GFDEMO.EXE is a demonstration of the GFONTS.BAS tool package for
QuickBASIC programmers.
You will need either a color EGA card or a high resolution (640x480)
VGA card to run GFDEMO (although about 20 GFONTS routines will work
with CGA or HERC.) The four supplied font files and an EGA graphics
image file must reside on the drive you run GFDEMO from.
GFONTS.BAS is a package of assembly and QuickBASIC fonts intended to
be added to your graphics application programs. To date, there are
over 60 font routines included, and many of them allow you to BLOAD
one of two kinds of font files from disk. Each of the QB fonts is
in a separate subprogram for ease of use, speed, and to allow you to
select only those fonts you need for each program. The fonts range
from 8x8 pixels to screen size.
There are two groups of GFONTS and two methods to display each
group. The groups are 1) assembly language routines, and 2) BASIC
rotuines. Each of these can use use either the ROM character set(s)
already in your computer, or font files you BLOAD from disk. The
GFONTS package comes with three BASIC programs to demostrate the
various methods.
Because the fonts are in individual modules and in QuickBASIC it is
very easy to create your own using the supplied ones as templates.
The possibilities are endless in size, shape, and color (you could
even have each character in a font contain 16 colors!)
The assembly fonts are quite easy to use. Load QB with the GFASM
quicklibrary and they are ready to go! All 13 assembly fonts
together add less than 10k to your compiled program! And you can
use standard 4k font files and display them in 5 different sizes at
assembly language speed.
GFONTS also comes with an exclusive 16x24 pixel font editor called
BIGFONT.EXE. There is room in each character for 3 times the pixels
of the ordinary 8x16 ROM character set, allowing for finely detailed
fonts (italics, cursive, bold, thin, Greek, etc...) And best of all
they are displayed at assembly language speed!
You may also load 8x16 font files (such as created with Michael
Mefford's FONTEDIT.COM from PC magazine) and display them with over
20 QuickBASIC GFONT routines; up to 480 pixels tall! This same disk
files can be displayed in assembly language using the VGAxxx calls.
The price for the GFONTS package is $40. This includes all source
code, over 25 font files, quick-reference sheets, and a variety of
GFONT examples and utilities in QuickBASIC; including a graphics
cursor routine, a Yes/No button routine, and a special VGA palette
fade demo program.
The GFONTS package comes on TWO 360k diskettes.
Support for BASIC 7.x is included at no extra charge.
You purchase full rights to all use of GFONTS (except distribution
as a graphics font toolbox, of course.) No royalties are required.
Thank you for trying the GFONTS demo. Feel free to call or write
with any questions.
