a freeware Windows program (open-source) for displaying spectra in the JCAMP-DX format.
Inspired by Dr. Robert Lancashire's JCAMP-DX
data viewer and its reincarnation in the MDL Chime
browser plug-in, JDXview was developed as an external "helper
application" which can be used in combination with web browsers, if
they do not have a suitable plug-in installed. JDXview displays various
kinds of spectra (NMR, IR, MS, etc.) in JCAMP-DX format. Supported
formats are: uncompressed (AFFN) and compressed (ASDF, e.g. DIFDUP) as
described in the 4.24 specification. Some features of more recent
JCAMP-DX versions are also implemented, but not all of them.
Furthermore, JDXview offers also rudimentary processing options: the
range of a spectrum can be clipped, and the result saved in JCAMP-DX
format again. Zooming and measuring of distances can be performed by
two cursors which are placed by pressing the left or right mouse
button, respectively, followed by a click on the "< >" button.
Graphics output is supported in the following vector graphics formats:
- HP-GL (Hewlett-Packard Graphics Language)
- SVG (Scalable Vector Graphics)
- EPS (Encapsulated PostScript)
JDXview is freely available
under the terms of the GNU General Public License
(GPL), for a detailed description of this license, please visit http://www.gnu.org/copyleft/gpl.html.
It is written in Delphi (Pascal) and it
was compiled with Borland Delphi 7 for the Windows operating system.
You may use it on your own risk, there is
no warranty for anything.
There is no special installation required. Simply copy the single
(jdxview.exe) to a suitable directory. You may add a desktop icon
and/or a start menu entry if desired. It is quite useful to associate
file type (extensions: .jdx, .dx) with JDXview. For use as a web
browser helper application, add or edit the settings for MIME type
"chemical/x-jcamp-dx" and enter jdxview.exe (if necessary, with its
full directory path) as the program to handle this file type.
JDXview does not access the Windows
registry nor any configuration file.
