Function Documentation

int jsqrt (  int  n  )

const char* libpet_roi_version (  void   )

int roi_append (  FILE *  fp, ROI *  roi )

int roi_append_n (  FILE *  fp, ROI_list *  rl, int  ind )

int roi_compute_circle (  ROI *  roi  )

int roi_compute_ellipse (  ROI *  roi  )

int roi_compute_rect (  ROI *  roi  )

void roi_delete (  ROI_list *  rl, ROI *  roi )

Deletes ROI from roilist

void roi_delete_n (  ROI_list *  rl, int  ind )

Deletes the index:th ROI

void roi_empty (  ROI_list *  rl  )

Allocated memory is freed, all data is cleared.

void roi_init (  ROI_list *  rl  )

Before any use, this should be called, but not later.

int roi_onoff (  ROI *  roi, int  dimx, int  dimy, float  zoom, char **  m )

The matrix is filled with 0's (outside of ROI) and 1's (inside the ROI border). If ROI extends outside image borders, those points are ignored. Matrix coordinates are up-to-bottom and left-to-right. Returns: Function returns 0, if everything is OK. Parameters: roi  Definitions for one region-of-interest dimx  Image matrix x dimension dimy  Image matrix y dimension zoom  Image zoom m  Allocated memory for output matrix[dimx][dimy]

void roi_print (  ROI *  roi  )

Prints the contents of (individual) roi data structure.

int roi_read (  const char *  fname, ROI_list *  rl )

Adds ROI file contents (all ROIs) to specified data structure. Returns: Returns 0, if OK.

int roi_save (  const char *  fname, ROI_list *  rl )
