Function Documentation

template<class POINT> vigra::Rect2D calcCircleROIFromPoints (  const POINT &  p1, const POINT &  p2 )

calculate the bounding box of a circle that goes through both points. the center of the circle is halfway between the two points

int ceili (  double  x  )  [inline]

IMPEX void hugin_utils::ControlPointErrorColour (  const double  cperr, double &  r, double &  g, double &  b )

IMPEX std::string hugin_utils::CurrentTime (   )

current time as a string

IMPEX std::string hugin_utils::doubleToString (  double  d, int  fractionaldigits = -1 )

convert a double to a string, suitable for display within a GUI. d value to convert t a string fractionaldigits number of fractional digits. -1: not specified, use default.

void hugin_utils::eig_jacobi (  int  n, double  a[3][3], double  v[3][3], double *  d, int *  ind, int *  maxsweep, int *  maxannil, double *  epsilon )

Implements jacobi eigenvalue/vector algorithm on a symmetric matrix stored as a 2 dimensional matrix a[n][n] and computes the eigenvectors in another globally allocated matrix v[n][n]. intput: n - size of matrix problem outputs: v - eigenvector matrix d[MAX] - a vector of unsorted eigenvalues ind[MAX] - a vector of indicies sorting d[] into descending order maxanil - number of rotations applied inputs/outputs a - input matrix (the input is changed) maxsweep - on input max number of sweeps on output actual number of sweeps epsilon - on input tolerance to consider offdiagonal elements as zero on output sum of offdiagonal elements

template<class str> str escapeStringMake (  const str &  arg  )

Escape dangerous chars in makefile strings/filenames (space),#,=.

template<class InputIterator1, class InputIterator2> double euclid_dist (  InputIterator1  first1, InputIterator1  last1, InputIterator2  first2 )

calculate squared Euclidean distance between two vectors.

void hugin_utils::findSubGraphs (  AdjListGraph &  graph, std::vector< int > &  subgraphStart )

find subgraphs Actually, we could just use the BOOST graph library instead of hacking our own graph functions.

int floori (  double  x  )  [inline]

IMPEX int hugin_utils::getCPUCount (   )

return the CPU count. On error returns a cpu count of 0 or -1

IMPEX std::string hugin_utils::getExtension (  const std::string &  basename  )

Get extension of a filename.

IMPEX std::string hugin_utils::getPathPrefix (  const std::string &  filename  )

Get the path to a filename.

int isnan (  double  x  )  [inline]

template<typename Target, typename Source> Target lexical_cast (  Source  arg  )

template<class T> double norm (  T  t  )

template<class str> str quoteFilename (  const str &  arg  )

Quote a filename, so that it is surrounded by "". I don't know the escape char for windows

template<class str> str quoteString (  const str &  arg  )

Try to escape special chars on windows and linux. : I'm quite sure that this routine doesn't replace some important shell chars I don't know of. This could lead to nasty behaviour and maybe even security holes.

template<class str> str QuoteStringInternal (  const str &  arg, const str &  quotechar, const str &  replacements )

template<class str> str quoteStringInternal (  const str &  arg, const str &  quotechar, const str &  replacements )

utility function; escapes characters in replacements with quotechar.

template<class str> str quoteStringShell (  const str &  arg  )

Try to escape special chars in a string used by a unix type shell. : I'm quite sure that this routine doesn't replace some important shell chars I don't know of. This could lead to nasty behaviour and maybe even security holes. Note that : and = are not special shell charaters but they also should be escaped because they causes problems with gnumake.

template<class str> str replaceAll (  const str &  arg, const str &  target, const str &  replacement )

double hugin_utils::round (  double  x  )  [inline]

float hugin_utils::roundf (  float  x  )  [inline]

template<class T> int roundi (  T  x  )  [inline]

template<class T> T simpleClipPoint (  const T &  point, const T &  min, const T &  max )

clip a point to fit int [min, max] does not do a mathematical clipping, just sets p.x and p.y to the borders if they are outside.

void sortd (  int  length, double *  a, int *  ind )

template<class T> T sqr (  T  t  )

template<class InputIterator1, class InputIterator2, class T> T sqr_dist (  InputIterator1  first1, InputIterator1  last1, InputIterator2  first2, T  res )

calculate squared Euclidean distance between two vectors.

template<typename STR> bool stringToDouble (  const STR &  str_, double &  dest )

convert a string to a double, ignore localisation. always accept both. sets dest to the new value, and returns true if it could be read. it the conversion fails, returns false and does not modify dest. Returns: success

IMPEX std::string hugin_utils::stripExtension (  const std::string &  basename  )

remove extension of a filename

IMPEX std::string hugin_utils::stripPath (  const std::string &  filename  )

remove the path of a filename (mainly useful for gui display of filenames)

std::string tolower (  const std::string &  s  )  [inline]

convert a string to lowercase

template<class FUNCTOR> void traverseEdges (  const AdjListGraph &  graph, int  startNode, FUNCTOR &  visitor )
