2) Set the choosen target as the active project, that means :
a) Go to the Menu 'Build -> Set Active Configuration'
b) Choose one of the following configuration :
- DllOpenJPEG - Win32 Release => creates a DLL in release mode named OpenJPEG.dll
- DllOpenJPEG - Win32 Debug => creates a DLL in debug mode named OpenJPEGd.dll
- LibOpenJPEG - Win32 Release => creates a static library in release mode named LibOpenJPEG.lib
- LibOpenJPEG - Win32 Debug => creates a static library in debug mode named LibOpenJPEGd.lib
3) Build the project : Menu -> Build -> Rebuild All
The build process will create a directory named 'dist' that will contain all you need in order to use the library.
Simple codec compilation
------------------------
Once you've built the library, you might want to test it with a basic codec. To do this, go to the codec directory and use one of the following projects to build an encoder and decoder respectively:
- image_to_j2k.dsw
- j2k_to_image.dsw
IMPORTANT NOTE :
----------------
The encoder and decoder samples are configured to use the static version of the library. A link to the LibOpenJPEG static project is included in these projects so that you can build both a codec and the library in a single pass.
However, you MUST NOTE that in order to use LibOpenJPEG as a static library in your program, you NEED to add the following compiler directive to your project : OPJ_STATIC
Look at the menu 'Project -> Settings -> C/C++ tab -> preprocessor definition' to see how this is configured.
When using OpenJPEG as a DLL, this compiler directive MUST NOT be used.
