    AttributedCharacterIterator aci = as.getIterator();

    int startIndex = aci.getBeginIndex();
    int endIndex = aci.getEndIndex();

    LineBreakMeasurer measurer;

    float wrappingWidth = (float) size.width;

    float Y = 0.0f;

    while (measurer.getPosition() < endIndex) {
        TextLayout layout = measurer.nextLayout(wrappingWidth);

        Y += layout.getAscent();

        float X = 0.0f;
