Constructor Detail

### PDFImage

    protected PDFImage(PDFObject imageObj)

  Create an instance of a PDFImage

Method Detail

### dump

    public static void dump(PDFObject obj)
                     throws java.io.IOException

  Throws:
    `java.io.IOException`

### p

    public static void p(java.lang.String string)

### createImage

    public static PDFImage createImage(PDFObject obj,
                                       java.util.Map resources)
                                throws java.io.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:
    `java.io.IOException`

### getImage

    public java.awt.image.BufferedImage getImage()

  Get the image that this PDFImage generates.

  Returns:
    a buffered image containing the decoded image data

### parseData

    protected java.awt.image.BufferedImage parseData(byte[] data,
                                                     java.nio.ByteBuffer jpegData)
                                              throws java.io.IOException

  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.

  Parameters:
    `data` - the data when already completely filtered and uncompressed
    `jpegData` - a byte buffer if data still requiring the DCDTecode filter is being used
  Throws:
    `java.io.IOException`

### getWidth

    public int getWidth()

  Get the image's width

### setWidth

    protected void setWidth(int width)

  Set the image's width

### getHeight

    public int getHeight()

  Get the image's height

### setHeight

    protected void setHeight(int height)

### getColorSpace

    protected PDFColorSpace getColorSpace()

  Get the colorspace associated with this image, or null if there isn't one

### setColorSpace

    protected void setColorSpace(PDFColorSpace colorSpace)

  Set the colorspace associated with this image

### getBitsPerComponent

    protected int getBitsPerComponent()
