Adds a point to the path by drawing a straight line from the current coordinates to the new specified coordinates specified in double precision.

Usage

From source file:org.apache.pdfbox.pdfviewer.font.CFFGlyph2D.java

private GeneralPath transformGlyph(GeneralPath glyph) {
    // we have to invert all y-coordinates due to the moved 0,0-reference
    PathIterator iter = glyph.getPathIterator(null);
    float[] currentSegment = new float[6];
    Path2D.Float path = new Path2D.Float(iter.getWindingRule());
    boolean glyphTransformed = false;
    while (!iter.isDone()) {
        glyphTransformed = true;//from w  w w .j a  v  a 2s.  c o  m
        int type = iter.currentSegment(currentSegment);
        switch (type) {
        case PathIterator.SEG_MOVETO:
            path.moveTo(currentSegment[0], -currentSegment[1]);
            break;
        case PathIterator.SEG_LINETO:
            path.lineTo(currentSegment[0], -currentSegment[1]);
            break;
