SYNOPSIS\n\
%s [-i <input image path>] [-p <personal image path>]\n\
[-f <first image>] [-l <last image>] [-s <step>]\n\
[-c] [-d] [-h]\n", name);
fprintf(stdout, "\n\
OPTIONS: Default\n\
-i <input image path> %s\n\
Set image input path.\n\
From this path read \"line/image.%%04d.%s\"\n\
images. \n\
Setting the VISP_INPUT_IMAGE_PATH environment\n\
variable produces the same behaviour than using\n\
this option.\n\
\n\
-p <personal image path> %s\n\
Specify a personal sequence containing images \n\
to process.\n\
By image sequence, we mean one file per image.\n\
Example : \"C:/Temp/visp-images/line/image.%%04d.%s\"\n\
%%04d is for the image numbering.\n\
\n\
-f <first image> %u\n\
First image number of the sequence.\n\
\n\
-l <last image> %u\n\
Last image number of the sequence.\n\
\n\
-s <step> %u\n\
Step between two images.\n\
\n\
-c\n\
Disable the mouse click. Useful to automate the \n\
execution of this program without human intervention.\n\
\n\
-d \n\
Turn off the display.\n\
\n\
-h\n\
Print the help.\n",
