ConvertHSItoPhotoCoords

Declaration:

TMetaData.ConvertHSItoPhotoCoords (PhotIx: integer; hsiX, hsiY: double; var PhotX, PhotY: integer): integer;

The function ConvertHSItoPhotoCoords transforms the coordinates of the point [hsiX, hsiY] on the hyperspectral image (world coordinates) into the corresponding photo coordinates [PhotX, PhotY] (pixel coordinates). The photo is given by the parameter PhotIx which can assume values between 1 and NumPhotos. The function returns the following error codes:  0 ... everything OK -1 ... the specified photo is not available (PhotIx is out of range) -2 ... the photo is not yet calibrated
