createPDFImage
Description copied from class:AbstractPDFImageHandler
Creates a PDF image object out of the given image.- Specified by:
createPDFImage
in classAbstractPDFImageHandler
- Parameters:
image
- an imagexobjectKey
- a key for retrieval of the image from the document's XObject collection- Returns:
- a suitable
PDFImage
implementation that can handle the flavour of the given image
-
getPriority
public int getPriority()Returns the priority for this image handler. A lower value means higher priority. This information is used to build the ordered/prioritized list of supported ImageFlavors. The built-in handlers use priorities between 100 and 999.- Returns:
- a positive integer (>0) indicating the priority
-
getSupportedImageClass
Returns theClass
subclass supported by this instance.- Returns:
- the image Class type
-
getSupportedImageFlavors
public org.apache.xmlgraphics.image.loader.ImageFlavor[] getSupportedImageFlavors()Returns theImageFlavor
s supported by this instance- Returns:
- the supported image flavors
-
isCompatible
public boolean isCompatible(RenderingContext targetContext, org.apache.xmlgraphics.image.loader.Image image) Indicates whether the image handler is compatible with the indicated target represented by the rendering context object and with the image to be processed. The image is also passed as a parameter because a handler might not support every subtype of image that is presented. For example: in the case ofImageXMLDOM
, the image might carry an SVG or some other XML format. One handler might only handle SVG but no other XML format.- Parameters:
targetContext
- the target rendering contextimage
- the image to be processed (or null if only to check based on the rendering context)- Returns:
- true if this handler is compatible with the target rendering context
