Usage

From source file:com.sciaps.utils.ImportExportSpectrumCSV.java

public void exportSpectrumFile(File saveFile, PiecewiseSpectrum spectrum) throws IOException {
    if (spectrum == null || saveFile == null) {
        logger_.warn("", "will not save spectrum csv file");
        return;// ww w  . ja va  2  s  .c  om
    }

    final UnivariateFunction intensity = spectrum.getIntensityFunction();

    BufferedWriter bout = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(saveFile)));
    try {
        bout.append("wavelength, intensity");
        bout.newLine();
        final DoubleRange range = spectrum.getValidRange();

        for (double x = range.getMinimumDouble(); x <= range.getMaximumDouble(); x += 1.0
                / EXPORT_SAMPLE_RATE) {
            double y = intensity.value(x);
            if (Double.isNaN(y)) {
                y = 0;
            }
            bout.append(Double.toString(x));
            bout.append(", ");
            bout.append(Double.toString(y));
            bout.newLine();
        }
    } finally {
        bout.close();

    logger_.info("saved spectrum csv file to " + saveFile.getAbsolutePath());
}
