Function Documentation

psArray* pmSourceContour (  psImage *  image, int  xc, int  yc, float  threshold )

psArray* pmSourceContour_Crude (  pmSource *  source, const psImage *  image, float  level )

pmSourceContour() Find points in a contour for the given source at the given level. If type is PM_CONTOUR_CRUDE, the contour is found by starting at the source peak, running along each pixel row until the level is crossed, then interpolating to the level coordinate for that row. This is done for each row, with the starting point determined by the midpoint of the previous row, until the starting point has a value below the contour level. The returned contour consists of two vectors giving the x and y coordinates of the contour levels. This function may be used as part of the model guess inputs. Other contour types may be specified in the future for more refined contours (TBD) Parameters: source  The input pmSource image  The input image (float) (this arg should be removed) level  The level of the contour
