Function Documentation

int irplib_spectrum_find_brightest ( const cpl_image *  in,
int  offset,
spec_shadows  shadows,
double  min_bright,
int  orient,
double *  pos 
)

Finds the brightest spectrum in an image.

Parameters:
in spectral image with spectra
offset the diff. between pos. and neg. spectra
shadows the spectral shadows
min_bright min. bright. required for a spectrum
orient 1 for vertical spec. 0 for horizontal ones
pos the computed spectrum position (1->npix)
Returns:
int 0 if ok, -1 in error case
Finds the brightest spectrum in an image by collapsing the image orthogonally to the spectrum orientation. Spectra are assumed to be horizontal for orient==0, vertical for 1
