System.Drawing.Graphics g

The graphics context to use for drawing
ITextMark mark

the mark which to draw a part of
System.Drawing.Rectangle boundingRectangle

the bounding rectangle for the mark part, as determined from a previous call to GetMarkPartBounds(Graphics, ITextMark, Rectangle, Boolean, Boolean), in window coordinates.
System.Drawing.Rectangle contentRectangle

the rectangle spanning the content to be marked on this line, relative to the control window
System.Boolean isFirstLine

true if this is the first line that the marked content spans.
System.Boolean isLastLine

true if this is the last line that the marked content spans.
