===================
Usage of graphic functions
~~~~~~~~~~~~~~~~~~~~~~~~~~
1. Kinds of the graphic display device.
C Executor for FS16/18 supports the following two graphic display devices.
(Refer also "36crt.man".)
(1) ACRTC Graphic.
This is the graphic display device that is equipped with FS16/18-B (and
a part of FS16/18-C). This name is derived from the graphic control LSI
(ACRTC chip) used for them. This supports, 640x400 dots, 8 colors for each
dot and overlapping display with the character screen (80-column x 25-line
(14-inch CRT) or 40-column x 16-line (9-inch CRT)). All graphic functions
provided by C Library are not used on the ACRTC Graphic.
For the ACRTC graphic, CRTC Display is always used as the character display
device.
(2) VGA Graphic.
This is the display device that is equipped with FS16/18-C and FS16i/18i.
This name is derived from the display control LSI (VGA compatible accelerator
chip for PC) used for them. The following 4 display modes are supported.
A. 640x400 dots, 16 colors for each dot, overlapped with the character
screen (80-column x 25-line). (This mode is compatible with the
ACRTC Graphic.)
B. 640x400 dots, 256 colors for each dot, not overlapped with the
character screen.
C. 640x480 dots, 16 colors for each dot, overlapped with the character
screen (80-column x 30-line).
D. 640x480 dots, 256 colors for each dot, not overlapped with the
character screen.
The application program can specify the graphic mode by calling
"_setvideomode" function. All graphic functions provided by C Library can be
used on the VGA Graphic. The user application program which is written for
the ACRTC Graphic (14-inch CRT) runs on 640x400x16 mode of the VGA Graphic
without any modification of the source program.
Only the display which is equivalent to 14-inch type display of the ACRTC
Graphic is available on the VGA Graphic.
