JPEG2000 Visualization Software
|
||||
|
||||
- OPJViewer
|
||||
|
||||
Version 0.1 alpha
|
||||
|
||||
===============================================================================
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
1. Scope
|
||||
=============
|
||||
|
||||
This document describes the installation and use of the OPJViewer in the framework of OpenJPEG library.
|
||||
|
||||
This implementation has been developed using the OpenJPEG library as decoding engine and wxWidgets 2.8.0 as GUI engine.
|
||||
|
||||
If you find some bugs or if you have problems using the encoder/decoder, please send an e-mail to jpwl@diei.unipg.it
|
||||
|
||||
|
||||
2. Installing the viewer
|
||||
==========================
|
||||
|
||||
There are two available options, at the moment: a) compile from source code, and b) download a precompiled binary. In order to perform option a), it is mandatory to have compiled and built the LibOpenJPEG_JPWL library and the wxWidgets 2.8.0 framework (you have to download it from http://www.wxwidgets.org/ and compile the wx* libraries).
|
||||
|
||||
2.1. Compiling the source code in Windows
|
||||
-------------------------------------------
|
||||
|
||||
These are the steps required to compile the viewer under windows.
|
||||
|
||||
a) Download at least the libonjpeg, jpwl, and opjviewer folders from the SVN trunk.
|
||||
b) Open the OPJViewer.dsw workspace with Visual C++ 6 and activate the "OPJViewer - Win32 Release" configuration.
|
||||
c) In the configuration settings, go to the C++ tab and modify the wxWidgets paths in order to reflect your wx* install configuration (Preprocessor -> Additional include directories): simply update each instance of the two wx paths, do not remove or add them.
|
||||
d) In the configuration settings, go to the Link tab and modify the wxWidgets path in order to reflect your wx* install configuration (Input -> Additional library path): simply update the wx path.
|
||||
e) In the configuration settings, go to the Resources tab and modify the wxWidgets path in order to reflect your wx* install configuration (Additional resource include directories): simply update the wx path.
|
||||
f) Build!
|
||||
g) Run!
|
||||
h) (OPTIONAL) Prepare an installer by compiling the InnoSetup script OPJViewer.iss (you need to download it from http://www.jrsoftware.org/isinfo.php).
|
||||
|
||||
2.2. Compiling the source code in Unix-like systems
|
||||
-----------------------------------------------------
|
||||
|
||||
The porting is possible and under way.
|
||||
|
||||
|
||||
3. General information on the viewer
|
||||
====================================
|
||||
|
||||
This viewer is conceived to open and display information and image of J2K, JP2, and MJ2 files.
|
||||
The viewer application graphical interface is divided into three main panels:
|
||||
- a browsing pane;
|
||||
- a viewing pane;
|
||||
- a log/peek pane.
|
||||
|
||||
The browsing pane will present the markers or boxes hierarchy, with position (byte number where marker/box starts and stops) and length information (i.e., inner length as signalled by marker/box and total length, with marker/box sign included), in the following form:
|
||||
|
||||
filename
|
||||
|
|
||||
|_ #000: Marker/Box short name (Hex code)
|
||||
| |
|
||||
| |_ *** Marker/Box long name ***
|
||||
| |_ startbyte > stopbyte, inner_length + marker/box sign length (total length)
|
||||
| |_ Additional info, depending on the marker/box type
|
||||
| |_ ...
|
||||
|
|
||||
|_ #001: Marker/Box short name (Hex code)
|
||||
| |
|
||||
| |_ ...
|
||||
|
|
||||
...
|
||||
|
||||
|
||||
The viewing pane will display the decoded image contained in the JPEG 2000 file.
|
||||
It should display correctly images as large as 4000x2000, provided that a couple of GB of RAM are available. Nothing is known about the display of larger sizes: let us know if you manage to get it working.
|
||||
|
||||
|
||||
The log/peek pane is shared among two different subpanels:
|
||||
|
||||
- the log panel will report a lot of debugging info coming out from the wx GUI as well as from the openjpeg library
|
||||
- the peek pane tries to give a peek on the codestream/file portion which is currently selected in the browsing pane. It shows both hex and ascii values corresponding to the marker/box section.
|
||||
|
||||
|
||||
4. Known bugs and limitations

||||
