How to draw dotted line in pdfBox

Question

I'm using Pdfbox to draw some line on my document. Code:

contentStream.drawLine(startX, startY, startX, endY);

The result is an straight line. I wonder Does the PdfBox can draw dotted line?

Answer 1

Use the setLineDashPattern() call before doing your drawLine call:

public void setLineDashPattern(float[] pattern, float phase)

example:

setLineDashPattern (new float[]{3}, 0);

will configure a line pattern with 3 on, 3 off, 3 on, 3 off, etc

setLineDashPattern (new float[]{3,1}, 0);

will configure a line pattern with 3 on, 1 off, 3 on, etc

for more details on dash patterns, see the PDF specification.
