    • ScalePageContent

      public ScalePageContent(PageRanges pages, float scaleX, float scaleY, float translateX, float translateY)
      Scales the specified pages' contents and translates the scaled content, leaving the page dimensions intact.
      Scaling values must be expressed as a fraction.
      Parameters:
      pages - the pages whose content to scale
      scaleX - the horizontal scaling factor, where 100% == 1.0f. Values greater than 1.0f may result in content appearing outside the media box.
      scaleY - the vertical scaling factor, where 100% == 1.0f Values greater than 1.0f may result in content appearing outside the media box.
      translateX - the horizontal translation value. Values outside the range [0.0, mediaBoxWidth - (mediaBoxWidth * shrinkX)] may result in content appearing outside the media box. You may query a page's media box using PdfManipulator.getPageMediaBox(int) getPageMediaBox(int)}.
      translateY - the vertical translation value. Values outside the range [0.0, mediaBoxHeight - (mediaBoxHeight * shrinkY)] may result in content appearing outside the media box. You may query a page's media box using PdfManipulator.getPageMediaBox(int).

    • ScalePageContent

      public ScalePageContent(PageRanges pages, float scaleX, float scaleY, int translatePreset)
      Scales the specified page's contents and translates the scaled content to an anchor location, leaving the page dimensions intact.
      Scaling values must be expressed as a fraction.
      Parameters:
      pages - the pages whose content to scale
      scaleX - the horizontal scaling factor, where 100% == 1.0f. Values greater than 1.0f may result in content appearing outside the media box.
      scaleY - the vertical scaling factor, where 100% == 1.0f Values greater than 1.0f may result in content appearing outside the media box.
      translatePreset - anchors the content to a side or corner of the page.
