title: PDFBox dotted pattern with gradient
body: <p>I already can add line using contentStream with methods:</p>
  
  <p>setLineWidth(h) - set line thickness </p>
  
  <p>setLineDashPattern(pattern, period) - pattern create needed space and dots e.g new float[]{0.075,2}</p>
  
  <p>setLineCapStyle(2) - set all dots as rectangle</p>
  
  <p>moveTo(x,y) - set start point</p>
  
  <p>lineTo(x,y) - set end point</p>
  
  <p>stroke() - print line</p>
  
  <p>but now for me need create a gradient from center of dot to edge of dot </p>
  
  <p>Could anybody give me advice how to add gradient? </p>
