How to set the color of a horizontal line in Prawn?

Question

How can I set the color of a horizontal_line in Prawn PDF?

This is what I've got:

horizontal_line 0, 540, :at => line

It seems this is nowhere documented in the manual.

Thanks for any help.

Answer 1

To draw a grey horizontal line you must use stroke_horizontal_rule.

This works:

pdf.stroke_color 'dddddd'
pdf.stroke_horizontal_rule

Answer 2

If I remember correctly you can use stroke_color to set the color on a line like:

    mypdf.stroke_color "f0ffc1"

or

    mypdf.stroke_color 0,0,0,0 // for CMYK

Hope it helps!
