This viewer is conceived to open and display information and image content of J2K, JP2, |
and MJ2 files. |
The viewer application 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. |
