      Returns the name of the color space.
      Specified by:
      getName in class PDColorSpace
      Returns:

    • getNumberOfComponents

      public int getNumberOfComponents()
      Description copied from class: PDColorSpace
      Returns the number of components in this color space
      Specified by:
      getNumberOfComponents in class PDColorSpace
      Returns:
      the number of components in this color space
    • getDefaultDecode

      public float[] getDefaultDecode(int bitsPerComponent)
      Description copied from class: PDColorSpace
      Returns the default decode array for this color space.
      Specified by:
      getDefaultDecode in class PDColorSpace
      Parameters:
      bitsPerComponent - the number of bits per component.
      Returns:
      the default decode array
    • getInitialColor

      public PDColor getInitialColor()
      Description copied from class: PDColorSpace
      Returns the initial color value for this color space.
      Specified by:
      getInitialColor in class PDColorSpace
      Returns:
      the initial color value for this color space
    • toRGB

      public float[] toRGB(float[] value)
      Description copied from class: PDColorSpace
      Returns the RGB equivalent of the given color value.
      Specified by:
      toRGB in class PDColorSpace
      Parameters:
      value - a color value with component values between 0 and 1
      Returns:
      an array of R,G,B value between 0 and 255
    • toRGBImage

      public BufferedImage toRGBImage(WritableRaster raster) throws IOException
      Description copied from class: PDColorSpace
      Returns the (A)RGB equivalent of the given raster.
      Specified by:
      toRGBImage in class PDColorSpace
      Parameters:
      raster - the source raster
      Returns:
      an (A)RGB buffered image
      Throws:
      IOException - if the color conversion fails
    • toRawImage

      public BufferedImage toRawImage(WritableRaster raster)
      Description copied from class: PDColorSpace
      Returns the image in this colorspace or null. No conversion is performed. For special colorspaces like PDSeparation the image is returned in the gray colorspace. For undefined colorspaces like DeviceCMYK/DeviceRGB and DeviceGray null is returned. You can always fallback to PDColorSpace.toRGBImage(WritableRaster) if this returns null.
      Specified by:
      toRawImage in class PDColorSpace
      Parameters:
      raster - the source raster
      Returns:
      an buffered image in this colorspace. Or null if it is not possible to extract that image with the original colorspace without conversion.
    • getCOSObject

      public COSBase getCOSObject()
      Description copied from interface: COSObjectable
      Convert this standard java object to a COS object.
      Specified by:
      getCOSObject in interface COSObjectable
      Overrides:
      getCOSObject in class PDColorSpace
      Returns:
      The cos object that matches this Java object.
