- 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.
-
- GV057.ZIP contains GV057.EXE, 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.
-
- You may change the name GV057.exe to GV.exe in your personal use.
- Since "GV.exe" is a kind of common name, please identify this program by
- the icon. Please take care not to erase any previous 'GV.exe' file, if
- exists. (GV could be short for 'Gazou Vi (Beautifulness of the pictures)'.)
-
- >Features
- 1. A graphic file viewer on Windows
- 2. This program changes palettes, when viewing 16 color data file, on VGA
- (IBM-PC compatible) or on PC9801 by option.
- 3. Graphic formats include most prevalent graphic formats used in Japanese
- computer networks, including GIF and JPEG format. And more in the near
- future (^_^;).
- 4. Comments added to graphics are also shown.
-
- Among them, #2 enable 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++ using PC9801.
- The operation was confirmed by the following computers:
- IBM-PC compatible with VGA, SVGA
- PC-9801RA2
- J-3100 SGT Windows ver.3.0
- PC-H98
- PS/55Z XGA
- FM TOWNS model SF
-
- >How to use
- ( GV for GV057.exe )
- GV [<CPU opt.> | /FP | /PG <Pager> | /UC | /EXT=<TYPE> | /JFAST] [<DataFile>]
- <CPU opt.>:
- { /98 | /98N | /98E | /98E0 | /98EA | /GA | /VGA }
- <TYPE>:
- { MAG | MKI | Q4 | JPG | GIF | XBM | X | BMP | ALL }
-
- Please start this program from Windows. You may select options from the
- menu given by this program later. Also you may start this program associated
- with the graphic file by giving the name of <DataFile>.
-
- >Graphic formats
- 1. MAG: MAKI02 format developed by Maki-chan NET
- 2. MAKI: MAKI01A, MAKI01B format developed by Maki-chan NET
- 3. Q4: Q4 format developed on PCVAN and NIFTY by the QLD-group
- 4. JPEG: JFIF format by JPEG
- 5. GIF: GIF format developed on CompuServe.
- 6. XBM: Bit map format used in X Windows
- 7. X: Modifed XBM format developed by JUNET
- 8. BMP: Bit map format used in MS Windows
- 9. 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) 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.
-
- The following modes are optional:
- 1) Color reduction mode (1PASS/2PASS)
- 2) Dithering (on/off)
- 3) Number of reduced color (256/16)
- 4) CPU (386 or more/ less)
-
- 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.
-
- 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) Right or left rotation
- 3) Linked display with multiple graphic data
- 4) Automatic window size adjustment
- 5) Information of comments on the graphics data
- 6) Display of the document file
- 7) 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.
-
- 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) Re-drawing option when non-active (/UC)
- When this option is on and GV.exe is in non-active window, this option
- forces the re-drawing of the picture by adjusting the colors as truly as
- possible.
- 10) Setting the default file type (/EXT=<TYPE>)
- This option determine the graphic data file type at the beginning of this
- program. <TYPE> can be the format which this program support and ALL.
- When you don't select this option, the <TYPE> is MAG.
- 11) JPEG fast drawing (/JFAST)
- When this option is selected, the reduction of the colors to 256 colors
- are done by 1 PASS. This enables fast drawing but the reproducibility of
- color becomes less.
-
- >BUG
- Please inform the bugs to the author.
-
- >Limitations
- Some features of this program have not been well tested. Please send the
- report to the author when you try them.
- 1. MAKI01B 8color 200line format
- 2. Auto judgement of CPU (286 or not)
-
- This program does not paste the logical palettes. Therefore data exchange
- might be in failure, when the application does not copy the DIB to clip
- board.
-
- The drawing speed of JPEG graphic data is a kind of slow (;_;).
-
- >Modifications in the next version
- The following modifications are under consideration for the next version.
- Please give the advice.
-
- 1. quicker depicting of JPEG graphic data (if possible)
- 2. PIC format (please give me more information m(o)m )
- 3. PI format (please give me more information, too m(o)m )
- 4. GIF89a format
- 5. graphic data selection from keyboard
- 6. Modification to the graphics (sharpness, brightness etc.)
-
- Any graphics format in which the author is interested will be added to this
- list soon.
