    • setColorprovider

      @Deprecated public void setColorprovider(ColorProvider colorProvider)
      Deprecated.
      As of i-net PDFC 4.1, use PDFComparer.setSettings(Settings) instead (Settings.setColor(Color, ColorSetting))
      Set the ColorProvider used to paint the exported document.

      To define a custom color theme, override ColorProvider#getMarkerColor(GroupType) and ColorProvider#getOutlineColor(GroupType)

      Parameters:
      colorProvider - the ColorProvider used for the export

      i-net PDFC 3.2

    • setAddHeaderFooter

      @Deprecated public void setAddHeaderFooter(boolean addHeaderFooter)
      Deprecated.
      As of i-net PDFC 4.1, use PDFComparer.setSettings(Settings) instead (Settings.setEnabled(boolean, VisibilitySetting...)
      Set whether header and footer should be added to the document.
      This includes date, compared document names and page-number.

      Default is: true.

      Parameters:
      addHeaderFooter - true to add header and footer, otherwise false.

      i-net PDFC 3.0

    • setScaleToFitPageHeight

      @Deprecated public void setScaleToFitPageHeight(boolean flag)
      Deprecated.
      As of i-net PDFC 4.1, use PDFComparer.setSettings(Settings)
      Set that the Painter must scale the data to make the upper first page of both documents to fit on one (the first) exported page. This is useful if both documents have few and small differences and a landscape page layout is used or only one side (LEFT or RIGHT) is printed.

      If setPaintSides(byte) is PAINT_LEFT or PAINT_RIGHT and Settings.setEnabled(boolean, VisibilitySetting...) with Settings.EXPORT#SCALETOPAGEHEIGHT is true, one exported page will always contain exactly one page of the original document. To export a document which looks like the original document plus differences highlighted you must additionally set setAddHeaderFooter(boolean) to false and make sure the page layout of the export corresponds to the layout of the original document.

      If this is false, the Painter will scale the document to take the full width of the page.

      Default is: false.

      Parameters:
      flag - true to scale to make both pages of both documents to fit on one page, otherwise the default scale-to-width behavior is used.
      Since:
      i-net PDFC 3.0

    • setBackgroundColor

      public void setBackgroundColor(Color backgroundColor)
      Set the background color of the print. This color is used for the areas where to page is, between the pages. Set to null to skip painting a background.

      default is White for PDF and null for PNG or Print.

      Parameters:
      backgroundColor - the background color of the PrintPainter

    • setPaintSides

      public void setPaintSides(byte sides)
      Set weather the first or the second of both compared documents must be painted.

      Default is PAINT_BOTH

      This option has no effect if setPaintOverlap(boolean) is set to true.

      Parameters:
      sides - document sides to paint, can be PAINT_LEFT, PAINT_RIGHT or PAINT_BOTH

      i-net PDFC 3.0

    • setPaintOverlap

      public void setPaintOverlap(boolean paintOverlap)
      Set to true if the compared documents must be exported in overlapping mode.

      Default is false.

      If this is true, the option setPaintSides(byte) has no effect.

      Parameters:
      paintOverlap - the paintOverlap of the PrintPainter
      Since:
      i-net PDFC 3.0

    • setOverlapAlpha

      public void setOverlapAlpha(float overlapAlpha)
      Set the alpha to use for overlapping export. Has only an effect if setPaintOverlap(boolean) is true. Must be between 0.0 and 1.0, where 0 means the right document completely overwrites the left document and 1 means the left document overwrites the right document.

      Default is 0.5.

      Parameters:
      overlapAlpha - the overlapAlpha of the PrintPainter
      Throws:
      IllegalArgumentException - if overlapAlpha is invalid
