Introduction

NxV is an 2D image editor with functionalities dedicated to people who use images analysis systems.

This software is under GPL and use TrollTech Qt 4 Open Source libraries

Many files are supported (PNG, JPG, BMP, TIF with TIffIO plugin, ...) and many operations are available :

• 2D image Display
• Histogram view
• Profile of a specific line
• 3D projections
• Color table modification for gray level images
• Simple operation on images (mirror, invert, ...)

Compilation

In order to compile NxV some packages need to be installed : Qt - Qwt 5.0.x - Qwtplot3d 0.2.6 - TiffIO-120e The installation procedure is explained in the following sections

Linux

1. Compile Qt

Download the Qt source for linux X11

Extract the package using this command:
tar xvfz qt-x11-opensource-src-{version}.tar.gz

Configure and compile in root:
./configure && make && make install

Add the following lines at the end of your ~/.bashrc:
export QTDIR=/usr/local/TrollTech/Qt-{version}
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
export PATH=$QTDIR/bin:$PATH

Restart your terminal or type :
source ~/.bashrc

2. Compile Qwt

Download the Qwt source

Extract the package using this command:
tar xvfj qwt-{version}.tar.bz2

Configure and compile in a user terminal:
qmake -makefile qwt.pro && make
su -c "make install"

Add the following lines at the end of your ~/.bashrc:
export QWT=/usr/local/qwt
export LD_LIBRARY_PATH=$QWT/lib:$LD_LIBRARY_PATH

3. Compile Qwtplot3d

Download the Qwtplot3d source

Extract the package using this command:
tar xvfz qwtplot3d-{version}.tgz

Configure and compile in a user terminal:
qmake -makefile qwtplot3d.pro && make

Move the entire directory qwtplot3d in /usr/local

Add the following lines at the end of your ~/.bashrc:
export QWTPLOT3D=/usr/local/qwtplot3d
export LD_LIBRARY_PATH=$QWTPLOT3D/lib:$LD_LIBRARY_PATH

4. Compile TiffIO

Download the TiffIO source

Extract the package using this command:
tar xvfz TiffIO-{version}.tgz

Configure and compile in a user terminal:
qmake -makefile qmake TiffIO.pro && make

In a root terminal, type:
make install

5. Compile NxV

Restart your terminal or type (to set QTDIR, QWT, QWTPLOT3D variable) :
source ~/.bashrc

Download the NxV source

Extract the package using this command:
tar xvfj nxv-{version}.tar.bz2

Configure and compile in a user terminal:
qmake -makefile nxv.pro && make

Execute NxV
./nxv

Windows

If you use mingw-gcc the compilation will be quite similar, but QT QWT and QWTPLOT3D variable must be set in the environment variables system

Moreover, before compiling qwtplot3d and if you use mingw-gcc, you must change in the qwtplot3d.pro this:
win32:TEMPLATE = vclib
by this:
win32:TEMPLATE = lib

Command Line

usage : nxv [options] [filelist]

-z{f} : set zoom factor to f

-w{i} : set window width to i

-h{i} : set window height to i

-RM : delete edited images on quit (WARNING)

example : nxv -RM -z1.5 -w512 -h512 /home/nxv/*.png

nxv will be started with a zoom factor set to 1.5, a 512 pixel width, a 512 pixel height, and all edited images will be deleted on application quit
