=============================================================== README.TXT 1996-08-11 =============================================================== GSview 2.0 - PostScript previewer. Needs Ghostscript 4.01. ======== Overview ======== GSview is a graphical interface for Ghostscript under MS-Windows or OS/2. 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 must be used with Ghostscript 4.01. Features include: - view pages in arbitrary order (Next, Previous, Goto). - selectable display resolution, depth, alpha. - page size is automatically selected from DSC comments or can be selected using the menu. - orientation is automatically selected from DSC comments or can be selected using the menu (Portrait, Landscape). - single button zoom - print selected pages using Ghostscript. page offset can be applied. - 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. - display PDF files - on-line help. - OS/2 or Win32 executables - installation program for GSview and Ghostscript - free (GSview Free Public Licence). New features in version 2.0: - 32-bit only. - Uses Ghostscript DLL. Should now be faster and more robust. - Multi-threaded under OS/2, Windows 95, Windows NT. - Single-threaded under Win32s (same EXE). - Ghostscript command line limit is much longer (1024 vs 127 bytes). - Supports long filenames with embedded spaces. (except in Start Menu or Program Manager). - More network friendly for installation. Can be run directly off a CD-ROM. - GSview now owns the image window, so "Options | Show BoundingBox" is now available under Windows. A few other nasties should also have been eliminated by this change. - Simple PDF viewer works better. - Handles documents that change the page size or resolution by simply ignoring these requests. - Better text display now that Ghostscript has better fonts. - Checks Ghostscript version. It will only operate with Aladdin Ghostscript 4.01. - pstotext for improved text extraction and searching. Highlights found words. Mark text for copying to the clipboard. - Setup program uses DLL version of unzip. - Anti-aliasing of text and graphics. - See gvcnews.txt in the GSview sources for more detailed change notes.

Disk 1: gsview.zip README.TXT (this file) LICENCE FILE_ID.DIZ os2setup.exe OS/2 installation program os2unzip.exe OS/2 Info-ZIP unzip utility setup.exe MS-Windows installation program wizunz32.dll MS-Windows Info-ZIP unzip utility emxrt.zip EMX Run Time library (OS/2 only). Disk 2: gs401ini.zip Aladdin Ghostscript library files PLUS gs401w32.zip MS-Windows Win32 Aladdin Ghostscript OR gs401os2.zip OS/2 Aladdin Ghostscript Disk 3: gs401fn1.zip Aladdin Ghostscript fonts. Disk 1 is the contents of gsview20.zip plus the file emxrt.zip obtained from ftp://ftp-os2.nmsu.edu/os2/unix/emx09b/emxrt.zip. Disks 2 and 3 are obtained from ftp://ftp.cs.wisc.edu/ghost/aladdin/ If using the floppy install method, 7Mbytes of hard disk space is required. To install from OS/2, run 'os2setup.exe' from disk 1. Make sure that the zip files are transferred in binary mode and are all present. The install program will not report bad zip files. For MS-Windows 3.1, you must have Win32s installed before installing GSview. See http://www.microsoft.com/ or ftp://ftp.microsoft.com/softlib/mslfiles/PW1118.EXE To install from MS-Windows, run 'setup.exe' from disk 1. The installation will overwrite any version of GSview or Aladdin Ghostscript in the destination directories. If you wish to save your Fontmap file, back it up to another directory. Make sure that the zip files are transferred in binary mode and are all present. If you don't like automatic installation programs, it is possible to install GSview and Ghostscript manually. See the Setup topic below for more details. If you wish to use install GSview without any prompts, give a destination directory on the command line. For example: setup c:\gstools 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. =========== Compilation =========== To compile GSview for OS/2 you need IBM NMAKE.EXE and EMX/GCC 0.9b. To create the GSview online help you need the IBM toolkit. Copy gvpm.mak to Makefile and edit COMPBASE and EMXPATH as required. Type 'nmake' To compile GSview for Windows you need Borland C++ 4.5. Copy gvwin.mak to Makefile then edit COMPBASE as required. Type 'make'. ===== Setup ===== These are the manual setup instructions. It is recommended that you use the installation program as described in the Installation section above. Create the directories gsview and gsN.NN (where N.NN is the Ghostscript version number). Copy gvpm.exe, gvpgs.exe and gvpm.hlp (OS/2) and/or gsview32.exe, gvwgs.exe, gsv16spl.exe and gsview.hlp (MS-Windows) and printer.ini to the GSview directory. Unzip Ghostscript into the gsN.NN directory and the Ghostscript fonts into gsN.NN\fonts. Start GSview and answer 'Yes' to all the configuration question. The configuration DEPENDS on ghostscript being in ../gsN.NN relative to the GSview directory. GSview (gvpm.exe) will run under OS/2 2.1 and OS/2 Warp. It may run under OS/2 2.0. PM GSview has been compiled with EMX/GCC 0.9b and requires the emx 0.9b DLL's. These are available from ftp://hobbes.nmsu.edu/os2/unix/emx09b/emxrt.zip GSview (gsview32.exe) will run under Windows NT, Windows 95 and Windows 3.1/Win32s. It will not run under Windows 3.0. See the on-line help for more details. The 'Common Problems' topic is worth reading if GSview won't work. ==== Bugs ==== Send bug reports to Russell Lang . (This is an alias provided by Aladdin Enterprises. Russell Lang is not an employee or agent of Aladdin Enterprises). 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. 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. Don't expect a fast response - the work I'm paid to do has a higher priority. ======= Updates ======= The latest version of GSview should be available from ftp://ftp.cs.wisc.edu/ghost/rjl/gsview*.zip or by mail (see next section). A World Wide Web home page for Ghostscript, Ghostview and GSview is at http://www.cs.wisc.edu/~ghost/ ================================== Copyright, Licensing and Donations ================================== GSview is copyright by Russell Lang.

The ps.c module is copyright by Tim Theisen and is covered by the licence in the file PUBLIC. GSview uses Ghostscript to display the contents of the PostScript files. Ghostscript is a separate program from GSview; it is written and owned by Aladdin Enterprises, not by Russell Lang. Aladdin Ghostscript comes with a licence that is more restrictive than the GNU Licence; in particular, it restricts the distribution of Aladdin Ghostscript in commercial contexts. Please see the file PUBLIC that accompanies Aladdin Ghostscript for more details. GSview uses pstotext in an external DLL. pstotext was written by Andrew Birrell and Paul McJones. It is Copyright (C) 1995-1996, Digital Equipment Corporation. See the licence in pstotext.txt or pstotext.zip for more details. If you do not agree to the pstotext licence, delete pstotext.zip, pstotxt2.dll and pstotxt3.dll. ================ Acknowledgements ================ Tim Theisen, who wrote Ghostview for X11 which provided the inspiration for GSview. Also for permission to use his ps.c module from Ghostview. L. Peter Deutsch, for writing Ghostscript and for making changes to Ghostscript to support GSview.
