This utility is a viewer of graphic files under the operation of MS Windows.
You will find this very useful especially when you use a high resolution
display.
GVIEW.ZIP contains GV.EXE, GV.HLP, README.JPN and README.ENG.
README.JPN is the original documentation written by Japanese.
If you have a DOS/V by IBM or a Toshiba T series personal computer
with "JSYS", you can display README.JPN properly.
** GV.HLP is only for Japanese. English version is not ready.
>Features
A graphic file viewer on Windows
This program changes palettes, when viewing 16 color data file, on VGA
(IBM-PC compatible) or on PC9801 by option.
Graphic formats include most prevalent graphic formats used in Japanese
computer networks, including GIF and JPEG format.
Among them, you to enjoy real colors, even if you are using fixed
palette environment like VGA or PC9801. (You know that under usual
circumstances, 16 color palettes are fixed in Windows. However this program
changes the palette.)
>CPU
This program was compiled by Borland C++ v3.1 using PC9821Ap.
The operation was confirmed by the following computers:
PC-9821Ap
IBM-PC compatible with VGA, SVGA
PC-9801RA2
J-3100 SGT
PC-H98
PS/55Z XGA
FM TOWNS model SF
under the control of Windows ver.3.0/3.1

6. PIC: format developed by Mr. Yanagisawa for X68K (Sharp)
7. XBM: Bit map format used in X Windows
8. X: Modified XBM format developed by JUNET
9. BMP: Bit map format used in MS Windows 3.0 OS/2
10. Automatic mode: Identifying the format by the suffix shown above
Details of the display of the formats
MAG
Partial pictures are displayed as follows:
1) When no pictures are shown before the partial picture, it is shown
normally.
2) When the number of planes of the color is different from that of
the picture shown before, it is shown normally.
3) When the specified position is out of the range of the picture shown
before, it is shown at the position where normally displayed.
4) When the size of data is more than 640 x 400, it is shown normally.
5) Otherwise, the partial picture data is displayed at the specified position
on the previous picture as a mixed graphics.
Q4
BAT file included in the Q4 graphic data is neglected.
JPEG
JFIF data format is displayed.
This software is based in part on the work of the Independent JPEG Group.
GIF
GIF87a and GIF89a(one file one graphic only) formats are displayed.
Basically GIF87a is the format that this program supports.
The Graphics Interchange Format(c) is the Copyright property of
CompuServe Incorporated. GIF(sm) is a Service Mark property of
CompuServe Incorporated.
PIC
You can change the aspect ratio. This program supports the following
types; 0x00/0x01/0x03/0x11/0x21/0x52/0xC2/0x0F/0X1F/0XFF and 16/256/
4096/32K/64K colors. This program does not support partial display.
BMP
Depend on the window versions, the color shown might be different. (For
example, NEC Windows and EPSON Windows even used on the same computer,
give you different results.)
This program didn't correct these differences.
>Other features
Basically this program is only used to show the graphic data. This program
doesn't support the picture format conversion. Besides this program can
do more on graphics displayed.
1) Copy/Paste with Clipboard (DIB,Bitmap)
2) Data save using BMP format.
3) Multiple graphic data can be shown by drag & drop
4) Right or left rotation
5) Linked display with multiple graphic data (auto/manual)
6) Automatic window size adjustment
7) Information of comments on the graphics data
8) Display of the document file
9) Display of the information of environment
Copy/Paste
Copy to the clip board is based on the copy of both DIB and Bit mapped
formats simultaneously. You may paste using DIB (prior) or Bit mapped
formats.
Data Save by BMP
Number of colors will be the same number which you used to show data.
When you want to save 256 colors using 16 color machine, you have to use
256 color, which is not beautiful.
Drag & Drop
You can select multiple files. Use left button on the mouse to show the
menu.
Next Data:
Previous Data:
DATA List...:
Double click of the left button enable you to precede the file.
Rotation
Link
When you want to link the graphic data next to the picture already shown,
you may use this feature. The size of the picture should fit to the
size of the previous picture already shown. When you want to add the
picture to the left side, you should remember that the horizontal size of
the picture has limitation. You may use this feature especially when you
display several Q4 formatted data files.
Auto adjustment of the size
To adjust the window size on the available screen size, you may use this
feature. This feature is useful especially after the rotation or the
movement.
Comment display
Information on the graphic data are shown. These include data size,
number of colors and comments appeared in the header of the graphic file
(header in MAG format, /*comment*/ in XBM format).
Document display
Document written on the DOC or Q4D file on the same directory can be
shown using "notepad.exe" etc. (you may specify it.) When you link
several graphics, the common part is used as the name of the document
file.
>More options
I am sorry! You find the forbidden options that depend on the machines.
1) PC98(N) (/98, /98N)
When the graphic data consist of 16 colors (palettes) and are shown in
the active window, palettes are chosen from 4096 colors. You should
use this option when you use PC9801 and NEC Windows.
2) PC98(E.0) (/98E, /98E0)
When the graphic data consist of 16 colors (palettes) and are shown in
the active window, palettes are chosen from 4096 colors. You should
use this option when you use PC9801 and EPSON Windows ver.3.0.
(The palettes used in EPSON Windows are different from those of NEC Windows.)
3) PC98(E.A) (/98EA)
When the graphic data consist of 16 colors (palettes) and are shown in
the active window, palettes are chosen from 4096 colors. You should
use this option when you use PC9801 and EPSON Windows ver.3.0A.
(The palette used in EPSON Windows differ between the versions.)
4) GA1024i (/GA)
When the graphic data consist of 16 colors (palettes) and are shown in
the active window, palettes are chosen from 16 million colors. You should
use this option when you use PC9801 and GA1024i under fixed palette
window driver.
5) VGA (/VGA)
When the graphic data consist of 16 colors (palettes) and are shown in
the active window, palettes are chosen from 262144 colors. You should
use this option when you use IBM-PC VGA.
(The color adjustment may not good in this version.)
6) OTHERS (default)
Under this default option, graphics data are shown dependent to the
graphic driver used in the windows.
7) Fixed Palette (/FP)
The above modifications of palettes information are good only when the
picture is in active window. However when this option is on, the
information of palettes is good when the picture is not in active
window.
Other options are good in every machine.
8) Pager option for document display (/PG<pager>)
Please specify the name of the program which is used to display the
document file with path name. Default is "notepad.exe".
9) Setting the default file type (/EXT=<TYPE>)
