- GRAD graphics library is a collection of functions for drawing dots,
- lines, circles, ellipsis, arcs and also for region filling, characters
- display, printing ... et cetera. Several useful sample programs such as a
- sideway printing, a graphics and text merge printing and a graphics command
- interpreter are provided. The source listings of sample programs are included
- too. All the sample programs are in public domain.
-
- GRAD supports for CGA (640 X 200) and HGA (720 X 348) graphics mode.
- Other graphics display adapter can be configured too. However, graphics
- display device is not absolutely necessary in GRAD system because up to 9 user
- virtual screen with user definable size can be created at run time.
-
- The printers supported by GRAD are EPSON FX-80, OKIDATA ML192 or
- compatibles and laser printers using JLASER card. Instructions to configure
- GRAD for other printers are provided too.
-
- The major difference of GRAD library from other graphics library are its
- superior character display function and versatile printing functions. With
- GRAD library, less than 200 lines of commented coded are required to write a
- sideway printing program with user definable size, font type, spacing, top and
- bottom margins.
-
- Furthermore GRAD provides very high speed operations. To draw a
- horizontal line of length 300 pixels on a 8MHz, 1 wait state AT, it takes
- about 1 microsecond per pixel on average. The whole library uses integer
- arithmetic only. This ensures high speed operations with or without math
- co-processor.
-
- In order to use GRAD library, you have to configure the GRAD library for
- the display adapter and printer in your system. See INSTALL.DOC on information
- about installation.
-
- After installation, try out some of the features of GRAD library
- according to the instructions in TEST.DOC.
-
- The manual for GRAD library and the sample programs can be printed by
- copying the file GRADUSER.DOC to the printing device
-
- copy GRADUSER.DOC PRN
-
- or use the DOS printer spooler PRINT
-
- print GRADUSER.DOC
