      Specified by:
      resetMembers in class ImageReaderBase

    • getPICTFrame

      private Rectangle getPICTFrame() throws IOException
      Open and read the frame size of the PICT file.
      Returns:
      return the PICT frame
      Throws:
      IOException - if an I/O error occurs while reading the image.

    • readPICTHeader

      private void readPICTHeader(ImageInputStream pStream) throws IOException
      Read the PICT header. The information read is shown on stdout if "DEBUG" is true.
      Parameters:
      pStream - the stream to read from
      Throws:
      IOException - if an I/O error occurs while reading the image.

    • readPICTHeader0

      private void readPICTHeader0(ImageInputStream pStream) throws IOException
      Throws:
      IOException

    • drawOnto

      private void drawOnto(Graphics2D pGraphics) throws IOException
      Reads the PICT stream. The contents of the stream will be drawn onto the supplied graphics object.

      If "DEBUG" is true, the elements read are listed on stdout.

      Parameters:
      pGraphics - the graphics object to draw onto.
      Throws:
      IIOException - if the data can not be read.
      IOException - if an I/O error occurs while reading the image.

    • readPICTopcodes

      private void readPICTopcodes(ImageInputStream pStream) throws IOException
      Parse PICT opcodes in a PICT file. The input stream must be positioned at the beginning of the opcodes, after picframe. If we have a non-null graphics, we try to draw the elements.
      Parameters:
      pStream - the stream to read from
      Throws:
      IIOException - if the data can not be read.
      IOException - if an I/O error occurs while reading the image.

    • readCompressedQT

      private void readCompressedQT(ImageInputStream pStream) throws IOException
      Throws:
      IOException

    • readOpPackBits

      private void readOpPackBits(ImageInputStream pStream, boolean hasRegion, int pPixmapCount) throws IOException
      Throws:
      IOException

    • readOpDirectBits

      private void readOpDirectBits(ImageInputStream pStream, boolean hasRegion, int pPixmapCount) throws IOException
      Reads the data following a directBitsRect opcode.
      Parameters:
      pStream - the stream to read from
      pPixmapCount - the index of the bitmap in the PICT file, used for cahcing.
      Throws:
      IIOException - if the data can not be read.
      IOException - if an I/O error occurs while reading the image.

    • readOpBits

      private void readOpBits(ImageInputStream pStream, boolean hasRegion) throws IOException
      Throws:
      IOException

    • readRectangle

      private void readRectangle(DataInput pStream, Rectangle pDestRect) throws IOException
      Reads the rectangle location and size from an 8-byte rectangle stream.
      Parameters:
      pStream - the stream to read from
      pDestRect - the rectangle to read into
      Throws:
      NullPointerException - if pDestRect is null
      IOException - if an I/O error occurs while reading the image.

    • readRegion

      private Area readRegion(DataInput pStream, Rectangle pBounds) throws IOException
      Read in a region. The input stream should be positioned at the first byte of the region. pBounds is a rectangle that will be set to the region bounds. The point array may therefore be empty if the region is just a rectangle.
      Parameters:
      pStream - the stream to read from
      pBounds - the bounds rectangle to read into
      Returns:
      the area containing the region, or an empty polygon if the region is a rectangle.
      Throws:
      IOException - if an I/O error occurs while reading the image.

    • readPoly

      private Polygon readPoly(DataInput pStream, Rectangle pBounds) throws IOException
      Read in a polygon. The input stream should be positioned at the first byte of the polygon.
      Parameters:
      pStream - the stream to read from
      pBounds - the bounds rectangle to read into
      Returns:
      the polygon
      Throws:
      IOException - if an I/O error occurs while reading the image.
