## org.apache.fop.render.pdf
Class AbstractImageAdapter

    java.lang.Object
      org.apache.fop.render.pdf.AbstractImageAdapter

All Implemented Interfaces:
  PDFImage

Direct Known Subclasses:
  ImageRawCCITTFaxAdapter, ImageRawJPEGAdapter, ImageRawPNGAdapter, ImageRenderedAdapter

    public abstract class AbstractImageAdapter

extends java.lang.Object
implements PDFImage

Abstract PDFImage implementation for the PDF renderer.

Field Summary
`protected org.apache.xmlgraphics.image.loader.Image` | `image` the image

Constructor Summary
`AbstractImageAdapter(org.apache.xmlgraphics.image.loader.Image image, java.lang.String key)` Creates a new PDFImage from an Image instance.

Method Summary
`void` | `disallowMultipleFilters()` Disallows multiple filters.
`protected java.awt.color.ICC_Profile` | `getEffectiveICCProfile()` Returns the effective ICC profile for the image.
`int` | `getHeight()` Get the image height in pixels.
`PDFICCStream` | `getICCStream()` Get the ICC stream for this image.
`protected java.awt.color.ColorSpace` | `getImageColorSpace()` Returns the image's color space.
`java.lang.String` | `getKey()` Key to look up XObject.
`java.lang.String` | `getMask()` Get the PDF reference for a bitmap mask.
`java.lang.String` | `getSoftMask()`
`PDFReference` | `getSoftMaskReference()` Get the PDF reference for a soft mask.
`PDFColor` | `getTransparentColor()` Get the transparent color.
`int` | `getWidth()` Get the image width in pixels.
`boolean` | `isInverted()`
`boolean` | `isPS()` Check if this image is a PostScript image.
`boolean` | `isTransparent()` Check if this image has a transparent color transparency.
`boolean` | `multipleFiltersAllowed()` Indicates whether multiple image filters are allowed; this is implemented because Adobe Reader does not like multiple FlateDecode filters applied to an image even though that allowed by the PDF spec; this is probable due to security concerns since many PDF malware exploits, like zip bombs, make use of a chain of FlateDecode filters.
`void` | `populateXObjectDictionary(PDFDictionary dict)` Populates the XObject's dictionary with additional values.
`protected void` | `populateXObjectDictionaryForIndexColorModel(PDFDictionary dict, java.awt.image.IndexColorModel icm)` This is to be used by populateXObjectDictionary() when the image is palette based.
`void` | `setup(PDFDocument doc)` Setup the PDF image for the current document.
`static PDFDeviceColorSpace` | `toPDFColorSpace(java.awt.color.ColorSpace cs)` Converts a ColorSpace object to a PDFColorSpace object.

Field Detail

### image

    protected org.apache.xmlgraphics.image.loader.Image image

  the image

Constructor Detail

### AbstractImageAdapter

    public AbstractImageAdapter(org.apache.xmlgraphics.image.loader.Image image,
                                java.lang.String key)

  Creates a new PDFImage from an Image instance.

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

Method Detail

### getKey

    public java.lang.String getKey()

  Key to look up XObject. This should be a unique key to refer to the image.

  Specified by:
    `getKey` in interface `PDFImage`
  Returns:
    the key for this image

### getImageColorSpace

    protected java.awt.color.ColorSpace getImageColorSpace()

  Returns the image's color space.

  Returns:
    the color space

### 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`
  Parameters:
    `doc` - the PDF parent document (todo) Remove this and delegate to the XObject

### getEffectiveICCProfile

    protected java.awt.color.ICC_Profile getEffectiveICCProfile()

  Returns the effective ICC profile for the image.

  Returns:
    an ICC profile or null

### getWidth

    public int getWidth()

  Get the image width in pixels.

  Specified by:
    `getWidth` in interface `PDFImage`
  Returns:
    the image width

### getHeight

    public int getHeight()

  Get the image height in pixels.

  Specified by:
    `getHeight` in interface `PDFImage`
  Returns:
    the image height

### isTransparent

    public boolean isTransparent()

  Check if this image has a transparent color transparency.

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

### getTransparentColor

    public PDFColor getTransparentColor()

  Get the transparent color.

  Specified by:
    `getTransparentColor` in interface `PDFImage`
  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`
  Returns:
    the PDF reference for the mask image

### getSoftMask

    public java.lang.String getSoftMask()

  Returns:
    null (if not overridden)

### getSoftMaskReference

    public PDFReference getSoftMaskReference()

  Get the PDF reference for a soft mask.

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

### isInverted

    public boolean isInverted()

  Specified by:
    `isInverted` in interface `PDFImage`
  Returns:
    true for CMYK images generated by Adobe Photoshop

### isPS

    public boolean isPS()

    `getICCStream` in interface `PDFImage`
  Returns:
    the ICC stream for this image if any

### populateXObjectDictionary

    public void populateXObjectDictionary(PDFDictionary dict)

  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`
  Parameters:
    `dict` - the dictionary to fill

### populateXObjectDictionaryForIndexColorModel

    protected void populateXObjectDictionaryForIndexColorModel(PDFDictionary dict,
                                                               java.awt.image.IndexColorModel icm)

  This is to be used by populateXObjectDictionary() when the image is palette based.

  Parameters:
    `dict` - the dictionary to fill in
    `icm` - the image color model

### toPDFColorSpace

    public static PDFDeviceColorSpace toPDFColorSpace(java.awt.color.ColorSpace cs)

  Converts a ColorSpace object to a PDFColorSpace object.

  Parameters:
    `cs` - ColorSpace instance
  Returns:
    PDFColorSpace new converted object

### multipleFiltersAllowed

    public boolean multipleFiltersAllowed()

  Indicates whether multiple image filters are allowed; this is implemented because Adobe Reader does not like multiple FlateDecode filters applied to an image even though that allowed by the PDF spec; this is probable due to security concerns since many PDF malware exploits, like zip bombs, make use of a chain of FlateDecode filters.

  Specified by:
    `multipleFiltersAllowed` in interface `PDFImage`

### disallowMultipleFilters

    public void disallowMultipleFilters()

  Disallows multiple filters.
