Constructor Detail

### ImageRawPNGAdapter

    public ImageRawPNGAdapter(org.apache.xmlgraphics.image.loader.impl.ImageRawPNG image,
                              java.lang.String key)

  Creates a new PDFImage from an Image instance.

  Parameters:
    `image` - the image
    `key` - XObject key

Method Detail

### setup

    public void setup(PDFDocument doc)

  Setup the PDF image for the current document. Some image formats may need to access the document (for example to add an ICC profile to the document).

  Specified by:
    `setup` in interface `PDFImage`
  Overrides:
    `setup` in class `AbstractImageAdapter`
  Parameters:
    `doc` - the PDF parent document (todo) Remove this and delegate to the XObject

### getColorSpace

    public PDFDeviceColorSpace getColorSpace()

  Get the color space for this image. Possible results are: DeviceGray, DeviceRGB, or DeviceCMYK

  Returns:
    the color space

### getBitsPerComponent

    public int getBitsPerComponent()

  Get the bits per color component for this image.

  Returns:
    the bits per component

### isTransparent

    public boolean isTransparent()

  Check if this image has a transparent color transparency.

  Specified by:
    `isTransparent` in interface `PDFImage`
  Overrides:
    `isTransparent` in class `AbstractImageAdapter`
  Returns:
    true if it has transparency

### getTransparentColor

    public PDFColor getTransparentColor()

  Get the transparent color.

  Specified by:
    `getTransparentColor` in interface `PDFImage`
  Overrides:
    `getTransparentColor` in class `AbstractImageAdapter`
  Returns:
    the transparent color for this image

### getMask

    public java.lang.String getMask()

  Get the PDF reference for a bitmap mask.

  Specified by:
    `getMask` in interface `PDFImage`
  Overrides:
    `getMask` in class `AbstractImageAdapter`
  Returns:
    the PDF reference for the mask image

### getSoftMask

    public java.lang.String getSoftMask()

  Overrides:
    `getSoftMask` in class `AbstractImageAdapter`
  Returns:
    null (if not overridden)

### getSoftMaskReference

    public PDFReference getSoftMaskReference()

  Get the PDF reference for a soft mask.

  Specified by:
    `getSoftMaskReference` in interface `PDFImage`
  Overrides:
    `getSoftMaskReference` in class `AbstractImageAdapter`
  Returns:
    the PDF reference for a soft mask image (or null if there's no soft mask)

### getPDFFilter

    public PDFFilter getPDFFilter()

  Get the PDF Filter to be applied to the image.

  Returns:
    the PDF Filter or null

### outputContents

    public void outputContents(java.io.OutputStream out)
                        throws java.io.IOException

  Writes the raw, unencoded contents of the image to a given output stream.

  Parameters:
    `out` - OutputStream to write to
  Throws:
    `java.io.IOException` - if there creating stream

### getFilterHint

    public java.lang.String getFilterHint()

  Returns a hint in form of a String (Possible values from PDFFilterList) indicating which filter setup should be used to encode the object.

  Returns:
    the filter setup hint

### populateXObjectDictionary

    public void populateXObjectDictionary(PDFDictionary dict)

  Description copied from class: `AbstractImageAdapter`
  Populates the XObject's dictionary with additional values. The values are added to the dictionary after all the values obtained from other methods from this interface have been put into the dictionary. That allows to override certain values.

  Specified by:
    `populateXObjectDictionary` in interface `PDFImage`
  Overrides:
    `populateXObjectDictionary` in class `AbstractImageAdapter`
  Parameters:
    `dict` - the dictionary to fill

### issRGB

    protected boolean issRGB()

  Overrides:
    `issRGB` in class `AbstractImageAdapter`
