               BorderProps bpsBottom,
               BorderProps bpsLeft,
               BorderProps bpsRight)
                 throws java.io.IOException

Draws borders.

Parameters:

borderRect - the border rectangle

bpsTop - the border specification on the top side

bpsBottom - the border specification on the bottom side

bpsLeft - the border specification on the left side

bpsRight - the border specification on the end side

Throws:

java.io.IOException - if an I/O error occurs while creating the borders

drawBorderLine

protected abstract void drawBorderLine(int x1,
                  int y1,
