Nconvert with portable Ghostscript?

Post by Wizard » Sun Jan 24, 2016 7:27 pm

Hi!
I would like to use nconvert to convert pdf to png using portable Ghostscript from http://portableapps.com/apps/utilities/ ... t_portable
I put nconvert.exe inside "bin" folder of portable Ghostscript which contains gsdll32.dll, gsdll64.dll, gswin32.exe, gswin32c.exe, gswin64.exe and gswin64c.exe
I run "nconvert -out png a.pdf" and I get:
my_error_exit...<Not a JPEG file: starts with 0x25 0x50>
Error: Don't know how to read this picture (a.pdf)
So, nconvert doesn't recognise portable Ghostscript.
Is there anything I can do to fix this like some variable or temporary registry key to set or is portable Ghostscript too specific for portableapps.com apps?

i have the same problem.
When i open a folder where PDF documents are located, XNView hangs (NO RESPONDING).
WINXP SP3 with Acrobat Reader 10.0 x, as default PDF reader, and PDFCreator 1.1.0 and PDF XChangeReader (without shell extention installed) on the system as well. No Ghostscript installed on the system.

Where (in which file e.g. xnview.ini) should the XNVIEW_GS_DLL & XNVIEW_GS_LIB environment variables set?

manay thanks and rgs Bob
btw, in case you still have issue and for anyone else who finds the topic, environment variables are set in the control panel, not in XnView. They are under System -> Advanced -> Environment Variables, you have to create them if they aren't listed. Setting this should allow XnView to remain compatible with PDF-XChange, which is installed with dozens of applications. (Less so now that free alternatives like DoPDF and CutePDF exist.)
  • XNVIEW_GS_DLL = path of gsdll32.dll
  • XNVIEW_GS_LIB = path of Ghostscript's lib folder

Thanks XnTriq,

For the community, I reproduce a response of Pierre that could enhance the response.
I must work totally with portable application. So I think this solution (sent by Pierre) could be better (no environment variable)
[Pierre]
You must place a directory "Plugins\gs" with GS "bin" and "lib"
So XnView/NConvert will recognise it.
I'm going to try the solution and will be back for the result.

So it works fine !

You must unzip GhostScript Portable (GhostscriptPortable_9.18.paf.exe for me) in the directory ...xnview\plugins\gs (so it exists ...xnview\plugins\gs\bin, ...xnview\plugins\gs\lib ...)
And nconvert.exe MUST be in ...xnview\ directory (so don't move it)

The process seems to be quite long when working with (to) some USB key devices probably because of communication and recording in these special devices (sometimes very slow writing devices).
For example, converting to an USB key (known as slow - Lexar) is more than 60s time long, while the same to hard disk is 1/2 second.
