## Overview

GSview is a graphical interface for Ghostscript under MS-Windows, OS/2 and Unix. Ghostscript is an interpreter for the PostScript page description language used by laser printers. For documents following the Adobe PostScript Document Structuring Conventions, GSview allows selected pages to be viewed or printed. GSview requires Ghostscript 7.04 - 9.99.

Features include:

- Display and print PostScript and PDF files.
- View pages in arbitrary order (Next, Previous, Goto).
- Page size and Orientation are automatically selected from DSC comments or can be selected using the menu.
- Print selected pages using Ghostscript.
- Convert pages to bitmap, PDF or PostScript.
- Selectable display resolution, depth, alpha.
- Single button zoom.
- Extract selected pages to another file.
- Copy display bitmap to clipboard.
- Save clipboard bitmap as BMP file.
- Add bitmap or user preview to EPS file (Interchange, TIFF or Windows Metafile)
- Graphically select and show bounding box for EPS file.
- Extract bitmap preview or PostScript from DOS EPS file.
- Extract text or search for text.
- Can read gzip and bzip2 compressed PostScript and PDF files.
- On-line help.
- Win64, Win32, GNU/Linux executables. Older versions support OS/2 and Win16.
- Can be run directly off a CD-ROM or USB memory stick (Portable Application).
- English, Catalan, Dutch, French, German, Greek, Italian, Russian, Slovak, Spanish and Swedish languages.
- Per user initialisation files for Windows.
- Includes setup program.
- Free (Aladdin Free Public Licence).

GSview was written by Russell Lang at Ghostgum Software Pty Ltd.

## Installation

First uninstall any previous versions of GSview.

### Win32

Obtain GSview (gsv49w32.exe) from

> http://www.cs.wisc.edu/~ghost/gsview/get49.htm

Obtain GPL Ghostscript 9.02 (gs902w32.exe) from

> http://www.cs.wisc.edu/~ghost/doc/GPL/gpl902.htm

First install the GPL Ghostscript self extracting archive gs902w32.exe (or a later version if available) Then install the GSview self extracting archive gsv49w32.exe. Run GSview.

#### Win32 location details

By default, GSview is installed in the directory `c:\Program Files\Ghostgum`, which creates the sub-directories `c:\Program Files\Ghostgum\gsview` and `c:\Program Files\Ghostgum\pstotext`. The GSview executable is `c:\Program Files\Ghostgum\gsview\gsview32.exe`.

By default, GPL Ghostscript is installed in the directory `c:\gs`, which creates the sub-directories `c:\gs\gsN.NN` and `c:\gs\fonts`. The GPL Ghostscript executables are `c:\gs\gsN.NN\gswin32c.exe` for console mode and `c:\gs\gsN.NN\gswin32.exe` for windowing mode.

GSview normally locates GPL Ghostscript using registry entries created by the GPL Ghostscript setup program. If these do not exist, GSview will assume that Ghostscript is in an adjacent directory to GSview, usually `c:\Program Files\Ghostgum\gsN.NN` and `c:\Program Files\Ghostgum\fonts`.

### Win64 (AMD64)

Obtain GSview (gsv49w64.exe) from

> http://www.cs.wisc.edu/~ghost/gsview/get49.htm

First install the GPL Ghostscript self extracting archive gs902w64.exe (or a later version if available) Then install the GSview self extracting archive gsv49w64.exe. Run GSview.

This version requires that you have a 64-bit x64 processor (AMD64 or EM64T), and that you are also running a 64-bit version of Windows such as Windows XP x64 Edition. It will not run on the more common 32-bit Windows XP.

### Windows Vista

Use the Win32 or Win64 versions described above. Windows Vista as distributed does not include support for the WinHelp format used by GSview. When you try to view the GSview help file, you will get an error message, which will direct you to the Microsoft site to download the Windows Help utility.

### OS/2

Obtain GSview (gsv49os2.zip) from

> http://www.cs.wisc.edu/~ghost/gsview/get49.htm

Obtain GPL Ghostscript 8.60 (gs860os2.zip) from

> http://www.cs.wisc.edu/~ghost/doc/GPL/gpl860.htm

Unzip GSview to a temporary directory, change to the gsview2 subdirectory, place gs860os2.zip (or a later version) in the same directory, and then run os2setup.exe.

If you do not already have EMX installed on your system, you will also need to obtain the EMX Run Time library, emxrt.zip, from one of

> ftp://ftp-os2.cdrom.com/pub/os2/emx09d/emxrt.zip
> ftp://ftp-os2.nmsu.edu/pub/os2/dev/emx/v0.9d/emxrt.zip

If GSview refuses to run at all, make sure you do not have an old version of the emx DLL on your system.

GSview (gvpm.exe) will run under OS/2 2.1 and OS/2 Warp.

### X11/Unix

Copy `gsview`, `gsview-help`, `epstool` and `pstotext` to a directory on your search path. Copy `gvx*.htm` to the directory `/usr/share/doc/gsview-N.N`. Copy `printer.ini` to directory `/etc/gsview`. GSview stores configuration information in `$HOME/.gsview.ini`.

You must have the shared object version of Ghostscript 7.04 - 9.19, which should be included in recent GNU/Linux distributions. If you don't have the ghostscript shared object, you must first install Ghostscript, then the additional shared object files. To build the ghostscript shared object files, use '`./configure ; make so`'

A precompiled version is available for GNU/Linux. GSview can also be compiled for SunOS and SGI IRIX.

### General

Make sure that the zip/exe files are transferred in binary mode.

The Ghostscript fonts are used by Ghostscript alone. Your system Fonts folder will not be modified.

If you don't like automatic installation programs, it is possible to install GSview and Ghostscript manually. For Ghostscript, read the file gsN.NN\doc\Install.htm. For GSview, read the file gsviewen.hlp

If you wish to use install GSview without any prompts, give a destination directory on the command line. For example:

> setup "c:\Program Files\ghostgum"

This will not prompt for a destination directory and will overwrite files without asking.

Configuration of GSview will occur the first time it is run.

See the on-line help for more details. The 'Common Problems' topic is worth reading if GSview doesn't work.

## Compilation

To compile GSview for Windows you need MS Visual C++ 5, 6, 7, 7.1, 8 or 9. Copy srcwin/win.mak to Makefile, edit Makefile to set `VCVER` and `DEVBASE` as required, then type '`nmake`'. To build for Win64 use '`nmake VCVER=71 WIN64=1`'

To compile GSview for OS/2 you need IBM NMAKE.EXE and EMX/GCC 0.9d. To create the GSview online help you need the IBM toolkit. Copy srcos2/os2.mak to Makefile and edit COMPBASE and EMXPATH as required. Type 'nmake'

To compile GSview for X11/Unix you need gcc and the GTK+ 1.2 toolkit. Unzip the sources as follows to convert the line endings:

      unzip -aa gsv49src.zip
      unzip -o gsv49src.zip "gsview-4.9/binary/*"
      cd gsview-4.9
      cp srcunx/unx.mak Makefile
      make

GSview may also be available in a tar.gz file which already has Unix line endings. To install, run `make install` See the X11/Unix topic for more notes on X11 GSview. For SunOS or SGI IRIX, uncomment the appropriate lines in the makefile. You also be able to use

      rpmbuild -ta gsview-4.9.tar.gz

## X11/Unix

X11 GSview is written by a novice at X Windows programming. It might have serious problems. The GTK+ toolkit is used for most of the graphical interface, with a very small amount of Xlib.

GSview on Unix uses the Ghostscript shared object. Drawing (especially over a network when using anti-aliased text) should be faster.

### Unimplemented features

- Help uses HTML and netscape. Gnome Help Browser is not used because it doesn't support #topic on the command line. For example: gnome-help-browser file:/path/gsview.htm#Page_Size If you know of a way to tell the Gnome Help Browser to jump to a particular topic, particularly without opening another copy of the browser, please let me know.
- Keyboard movement between widgets
- Full screen not implemented
- Clipboard operations
- Sounds

### Known problems

- Fit window doesn't get the correct dimension of the scrolled window client area, so the resize is slightly wrong. At the moment we use the size of the scroll window less the two scroll bars.
- GSview still includes lots of debugging code.

### Requests

Suggestions from GTK+ programmers about how to improve GSview.

Bug reports. Use "gsview -d9" to get debugging messages on stdout.

## Bugs

Send bug reports to Russell Lang at Ghostgum Software Pty Ltd, `gsview` at `ghostgum.com.au`. When reporting bugs, please include the version number and date of GSview (from the Help | About box), the version number of Ghostscript, and the exact wording of any error messages. The text in the "Ghostscript Messages" dialog can be copied to the clipboard and pasted as text (not bitmap please!) into an email message. Do not send me large files (>100k bytes) unless requested. If you get a SYS3175 or GPF, please send the address of the GPF - I can use this to help locate the bug. Please distinguish between bugs in GSview and bugs in Ghostscript, by making sure that the problem only occurs when using GSview, and not when using Ghostscript alone. Don't expect a fast response - the work I'm paid to do has a higher priority. For a list of known bugs, see http://www.cs.wisc.edu/~ghost/gsview/bugs.htm
