Function Documentation

static void fill_traceroi (  char **  m, int  dimx, int  dimy, float  f, int  pos_x, int  pos_y, int *  roix, int *  roiy, int  point_nr )  [static]

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.

int roi_mframe (  int  matnum  )

Returns the frame number of specified matrix

int roi_mplane (  int  matnum  )

Returns the plane number of specified matrix

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 reconstruction 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 (  char *  fname, ROI_list *  rl )

int roiAppend (  char *  fname, ROI_list *  rl, int  ind )

int roiComputeCirc (  ROI *  roi  )

int roiComputeElli (  ROI *  roi  )

int roiComputeRect (  ROI *  roi  )

void roiDel (  ROI_list *  rl, int  ind )

If ind=0, all ROIs in list are deleted keeping memory allocated, else only one ROI is deleted (ind=1, first ROI) keeping memory allocated.

int roiFillGaps (  int *  x, int *  y, int  nr, int **  ffx, int **  ffy )

Fills the gaps between ROI points; join them with new points. Allocates memory for new point data in fx and fy. Returns: Returns the number of new points or =< 0, if error.

void roiInit (  ROI_list *  rl  )

Before any use, this should be called, but not later. Note. Rename to roi_init() when the old functions are removed

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

The matrix is filled with 0's (outside of ROI), 1's (on the ROI border), and 2'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 reconstruction zoom m  Allocated memory for output matrix[dimx][dimy]

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

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

int roiSave (  char *  fname, ROI_list *  rl )
