java.lang.Objectorg.apache.fop.pdf.AlphaRasterImage
public class AlphaRasterImage
PDFImage implementation for alpha channel "images".
| Constructor Summary | |
|---|---|
AlphaRasterImage(java.lang.String k,
java.awt.image.Raster alpha)
Create a alpha channel image. |
|
AlphaRasterImage(java.lang.String k,
java.awt.image.RenderedImage image)
Create a alpha channel image. |
|
| Method Summary | |
|---|---|
int |
getBitsPerComponent()
Get the bits per color component for this image. |
PDFDeviceColorSpace |
getColorSpace()
Get the color space for this image. |
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. |
int |
getHeight()
Get the image height in pixels. |
PDFICCStream |
getICCStream()
Get the ICC stream for this image. |
java.lang.String |
getKey()
Key to look up XObject. |
java.lang.String |
getMask()
Get the PDF reference for a bitmap mask. |
PDFFilter |
getPDFFilter()
Get the PDF Filter to be applied to the image. |
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 |
outputContents(java.io.OutputStream out)
Writes the raw, unencoded contents of the image to a given output stream. |
void |
populateXObjectDictionary(PDFDictionary dict)
Populates the XObject's dictionary with additional values. |
void |
setup(PDFDocument doc)
Setup the PDF image for the current document. |
