ImageRawPNGAdapter
Creates a new PDFImage from an Image instance.- Parameters:
image
- the imagekey
- XObject key
-
-
Method Details
-
setup
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 interfacePDFImage
- Overrides:
setup
in classAbstractImageAdapter
- Parameters:
doc
- the PDF parent document (todo) Remove this and delegate to the XObject
-
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. Classes such asPDFImageXObject
rely on this simple binary model of transparency (e.g. compare toTransparency
) 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 colors.- Specified by:
isTransparent
in interfacePDFImage
- Overrides:
isTransparent
in classAbstractImageAdapter
- Returns:
- true if it has at least one fully transparent color
-
getTransparentColor
Get the transparent color.- Specified by:
getTransparentColor
in interfacePDFImage
- Overrides:
getTransparentColor
in classAbstractImageAdapter
- Returns:
- the transparent color for this image
-
getMask
Get the PDF reference for a bitmap mask.- Specified by:
getMask
in interfacePDFImage
- Overrides:
getMask
in classAbstractImageAdapter
- Returns:
- the PDF reference for the mask image
-
getSoftMask
- Overrides:
getSoftMask
in classAbstractImageAdapter
- Returns:
- null (if not overridden)
-
getSoftMaskReference
Get the PDF reference for a soft mask.- Specified by:
getSoftMaskReference
in interfacePDFImage
- Overrides:
getSoftMaskReference
in classAbstractImageAdapter
- Returns:
- the PDF reference for a soft mask image (or null if there's no soft mask)
-
getPDFFilter
Get the PDF Filter to be applied to the image.- Returns:
- the PDF Filter or null
-
outputContents
Writes the raw, unencoded contents of the image to a given output stream.- Parameters:
out
- OutputStream to write to- Throws:
IOException
- if there creating stream
-
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
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 interfacePDFImage
- Overrides:
populateXObjectDictionary
in classAbstractImageAdapter
- Parameters:
dict
- the dictionary to fill
-
issRGB
protected boolean issRGB()- Overrides:
issRGB
in classAbstractImageAdapter
