| Constructor and Description |
|---|
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.
|
| Modifier and Type | Method and Description |
|---|---|
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.

PDFImageXObject rely on this simple
binary model of transparency (e.g. compare to
Transparency) in order to render
color key masking (see PDF Spec 1.7 Chapter 8.9.6.4).
Therefore only return true if image has fully transparent
