public abstract void draw(PdfCanvas canvas, float x1, float y1, float x2, float y2, Border.Side defaultSide, float borderWidthBefore, float borderWidthAfter)
Given points specify the line which lies on the border of the content area, therefore the border itself should be drawn to the left from the drawing direction.
borderWidthBefore
and borderWidthAfter
parameters are used to define the widths of the borders that are before and after the current border, e.g. for the bottom border, borderWidthBefore
specifies width of the right border and borderWidthAfter
- width of the left border. Those width are used to handle areas of border joins.
