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.

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

getICCStream

public PDFICCStream getICCStream()
Get the ICC stream for this image.

Specified by:
getICCStream in interface PDFImage
Overrides:
getICCStream in class AbstractImageAdapter
Returns:
the ICC stream for this image if any

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
