Hi,

I've downloaded ARToolKit 2.431, I'm not sure is
that's the latest version of ARToolKit.

In calib_dist.h there is a function declaration for
calc_distortion which is as follow:

void calc_distortion(CALIB_PATT_T *patt, int xsize,
int ysize, double dist_factor[3] );

I wonder whether the array size of dist_factor[] is 3
or 4, because in check_dist.c I found that the size of
array for dist_factor[] is 4.

Thanks.

Junaidi.

Right array size is 4.
So function declaration should be corrected like:

void calc_distortion(CALIB_PATT_T *patt, int xsize,
                     int ysize, double dist_factor[4] );
