Encapsulates a PDF Image

  • Constructor Details

    • PDFImage

      protected PDFImage(PDFObject imageObj)
      Create an instance of a PDFImage

  • Method Details

    • dump

      public static void dump(PDFObject obj) throws IOException
      Throws:
      IOException

    • p

      public static void p(String string)

    • createImage

      public static PDFImage createImage(PDFObject obj, Map resources) throws IOException
      Read a PDFImage from an image dictionary and stream
      Parameters:
      obj - the PDFObject containing the image's dictionary and stream
      resources - the current resources
      Throws:
      IOException

    • getImage

      public BufferedImage getImage()
      Get the image that this PDFImage generates.
      Returns:
      a buffered image containing the decoded image data

    • parseData

      protected BufferedImage parseData(byte[] data)

      Parse the image stream into a buffered image. Note that this is guaranteed to be called after all the other setXXX methods have been called.

      NOTE: the color convolving is extremely slow on large images. It would be good to see if it could be moved out into the rendering phases, where we might be able to scale the image down first.invalid input: '<'/p
