        public void setMediaBox​(RMRect aRect)
        Sets the media box for the page.
      • setCropBox

        public void setCropBox​(RMRect aRect)
        Sets the crop box for the page.
      • setFillColor

        public void setFillColor​(RMColor aColor)
        Sets the given color to be the current fill color.
      • setStrokeColor

        public void setStrokeColor​(RMColor aColor)
        Sets the given color to be the current stroke color.
      • setStrokeWidth

        public void setStrokeWidth​(float aWidth)
        Sets the given line width to be the current line width.
      • setLineCap

        public void setLineCap​(int aLineCap)
        Sets the line cap: 0=butt, 1=round, 2=square.
      • setLineJoin

        public void setLineJoin​(int aLineJoin)
        Sets the line join: 0=miter, 1=round, 2=bevel.
      • setOpacity

        public void setOpacity​(float anOpacity,
                               byte coverage)
        Sets the opacity to be the following value, for stroke operations, fill operations or both. Stupidly, there's no setOpacity or setRGBAColor op in PDF, so you have to modify the gstate parameter dict directly using the generic graphics state operator gs, which takes a name of a gstate map in page's ExtGState map (we have to add this silly little gstate map manually for each unique opacity).
