OPTIONS: Default\n\

Set image input path.\n\
From this path read \"Klimt/Klimt.pgm\"\n\

Setting the VISP_INPUT_IMAGE_PATH environment\n\
variable produces the same behaviour than using\n\
this option.\n\
\n\
-t <type of video device> \"%s\"\n\
String specifying the video device to use.\n\
Possible values:\n\
\"X11\": only on UNIX platforms,\n\
\"GTK\": on all plaforms,\n\
\"GDI\": only on Windows platform (Graphics Device Interface),\n\
\"D3D\": only on Windows platform (Direct3D).\n\
\"CV\" : (OpenCV).\n\
\n\
-l\n\
Print the list of video-devices available and exit.\n\
\n\
-c\n\
Disable the mouse click. Useful to automaze the \n\
execution of this program without humain intervention.\n\
\n\
-d \n\
Turn off the display.\n\
\n\
-h\n\
Print the help.\n\n", ipath.c_str(), display.c_str());
