GSview is a graphical interface for Ghostscript.
http://www.cs.wisc.edu/~ghost/gsview/

It asks for an installed Ghostscript,
but, in fact, I think it requires only settings of ABSOLUTE path to Ghostscript directory.

Based on the following information
http://yukongis.ca/bin/view/Main/GhostScript#Batch_Processing
I write a .bat file and a simple NSIS .exe to envoke GSview.

It dynamically sets environment variables before launching GSview, and it works.

And I would post the procedures after passing more tests.

FYI,

I've managed to get GSview 4.9 and Ghostscript 8.6 to run as portable apps with only a little juggling of files and haven't noticed any problems. It also works without changing any environment paths, the following should get it working:

1) Download both the apps from http://pages.cs.wisc.edu/~ghost/gsview/
- Note that I've only tried the win32 versions.

2) Both downloads are self executing zip files, rather than executing them use a program such as 7-Zip portable and extract both GSview (gsv49w32.exe) and GhostScript (gs860w32.exe) to a new directory.

Your folder layout should look like this:

New Folder
     ├───gs860w32
     │      ├───fonts
     │      └───gs8.60
     │              ├───bin
     │              ├───doc
     │              ├───examples
     │              ├───lib
     │              └───Resource
     │                      ├───CMap
     │                      ├───ColorSpace
     │                      ├───Decoding
     │                      └───Encoding
     └───gsv49w32
             ├───gsview
             └───pstotext

3) Open up the ".\gs860w32" folder and move both the "fonts" and "gs8.60" folders to the "..\gsv49w32" folder. You can then delete the "gs860w32" folder and its remaining files.

Your folder structure should now look like this:

New Folder
     └───gsv49w32
             ├───fonts
             ├───gs8.60
             │      ├───bin
             │      ├───doc
             │      ├───examples
             │      ├───lib
             │      └───Resource
             │              ├───CMap
             │              ├───ColorSpace
             │              ├───Decoding
             │              └───Encoding
             ├───gsview
             └───pstotext

4) That should be about it, to test it run the "GSviewPortable.exe" located within the "gsv49w32" folder. It should work fine and automatically locate GhostScript as it's within it's own folder.

5) The only remain steps is a little house keeping. I renamed the "gsv49w32" folder to something more appropriate like "GSview Portable". I also deleted the "setup.exe" file as it's not needed and also so my "PortableApps Menu" didn't add it to its application list. I also renamed the "GSviewPortable.exe", again so it appeared better named within the "PortableApps menu". If your tight for space deleting the doc folder within the "gs8.60" folder will reduce the app by around 8mb.

I hope helps anyone that finds PDF portability and manipulation useful. Any problems please let me know.

Kindest Regards,
Richard

hhmmm... I roughly know about what U 2 R talking about, but I must say that this is one very simple, and impressive scheme

Very well done uksamo!

(I'm definitely going to use this in the future!!)
