From source file:org.nmrfx.processor.gui.spectra.DrawSpectrum.java

private void genContourPath(DatasetAttributes dataGenerator, AXMODE[] axModes, Contour contours,
        final int coordIndex, GraphicsContext g2) {
    int lineCount = contours.getLineCount(coordIndex);
    float scale = Contour.getScaleFac() / Short.MAX_VALUE;
    double cxOffset = contours.xOffset;
    double cyOffset = contours.yOffset;
    g2.beginPath();//from  w  ww . ja v a2 s  .co m
    Dataset dataset = dataGenerator.getDataset();
    for (int iLine = 0; iLine < lineCount; iLine += 4) {
        if (cancelled) {
            System.out.println("can response1");
            break;
        }
        double xPoint1 = scale * contours.coords[coordIndex][iLine] + cxOffset;
        double xPoint2 = scale * contours.coords[coordIndex][iLine + 2] + cxOffset;
        double yPoint1 = scale * contours.coords[coordIndex][iLine + 1] + cyOffset;
        double yPoint2 = scale * contours.coords[coordIndex][iLine + 3] + cyOffset;
        xPoint1 = dataset.pointToPPM(dataGenerator.dim[0], xPoint1);
        xPoint2 = dataset.pointToPPM(dataGenerator.dim[0], xPoint2);
        yPoint1 = dataset.pointToPPM(dataGenerator.dim[1], yPoint1);
        yPoint2 = dataset.pointToPPM(dataGenerator.dim[1], yPoint2);

        double x1 = axes[0].getDisplayPosition(xPoint1);
        double x2 = axes[0].getDisplayPosition(xPoint2);
        double y1 = axes[1].getDisplayPosition(yPoint1);
        double y2 = axes[1].getDisplayPosition(yPoint2);

        g2.moveTo(x1, y1);
        g2.lineTo(x2, y2);
    }
    g2.stroke();
}
