+
+
+OSSIM plugins can be loaded in two ways.[[BR]]
+
+1) By putting an entry in you ossim preference file.  Note that this system allows for ordering.  Sample:
+{{{
+plugin.file1: /ossim/ossim_plugins/lib/libossimpng_plugin.so
+plugin.file2: /ossim/ossim_plugins/lib/libossimKakaduPlugin.so
+plugin.file3: /ossim/ossim_plugins/lib/libossim_plugin.so
+plugin.file4: /ossim/ossim_plugins/lib/libossimOpenJpeg_plugin.so
+plugin.file5: /ossim/ossim_plugins/lib/libossimreg_plugin.so
+}}}
+
+2) Placing the plugin in a directory that is automatically searched at run time.  On windows this is the directory where the applications are.  This system does not allow for ordering.
+
+'''Checking plugins:'''
+
+
+There are three ways to check your plugins:
+
+1) Use "ossim-info --plugins" to dump them:
+
+{{{
+$ ossim-info --plugins
+Plugin: /ossim/ossim_plugins/lib/libossimpng_plugin.so
+Plugin: /ossim/ossim_plugins/lib/libossimKakaduPlugin.so
+Plugin: /ossim/ossim_plugins/lib/libossim_plugin.so
+Plugin: /ossim/ossim_plugins/lib/libossimOpenJpeg_plugin.so
+Plugin: /ossim/ossim_plugins/lib/libossimreg_plugin.so
+Plugin: /ossim/ossim_plugins/lib/libossimgdal_plugin.so
+}}}
+
+2) Use "ossim-info --plugin-test" to check the plugin:
+
+{{{
+$ ossim-info --plugin-test /ossim/ossim_plugins/lib/libossimKakaduPlugin.so 
+Plugin loaded: /ossim/ossim_plugins/lib/libossimKakaduPlugin.so
+}}}
+
+3) Turn trace on for ossimDynamicLibrary:
+
+{{{
+$  imagelinker -T ossimDynamic
+ossimDynamicLibrary::load DEBUG:
+Loaded library:  /ossim/ossim_plugins/lib/libossimpng_plugin.so
+ossimDynamicLibrary::load DEBUG:
+Loaded library:  /ossim/ossim_plugins/lib/libossimKakaduPlugin.so
+ossimDynamicLibrary::load DEBUG:
+Loaded library:  /ossim/ossim_plugins/lib/libossim_plugin.so
+ossimDynamicLibrary::load DEBUG:
+Loaded library:  /ossim/ossim_plugins/lib/libossimOpenJpeg_plugin.so
+ossimDynamicLibrary::load DEBUG:
+Loaded library:  /ossim/ossim_plugins/lib/libossimreg_plugin.so
+ossimDynamicLibrary::load DEBUG:
+Loaded library:  /ossim/ossim_plugins/lib/libossimgdal_plugin.so
+}}}
+
+The third option will tell you if a plugin does not load.
