setAdditionalParameters
protected void setAdditionalParameters(AFPDataObjectInfo dataObjectInfo, org.apache.xmlgraphics.image.loader.impl.ImageRawStream image) Sets additional parameters on the image object info being built. By default, this method does nothing but it can be overridden to provide additional functionality.- Overrides:
setAdditionalParameters
in classAbstractAFPImageHandlerRawStream
- Parameters:
dataObjectInfo
- the image object info being builtimage
- the image being processed
-
handleImage
public void handleImage(RenderingContext context, org.apache.xmlgraphics.image.loader.Image image, Rectangle pos) throws IOException Handles the givenImage
instance painting it at the indicated position in the output format being generated.- Specified by:
handleImage
in interfaceImageHandler
- Overrides:
handleImage
in classAbstractAFPImageHandlerRawStream
- Parameters:
context
- the rendering contextimage
- the image to be handledpos
- the position and scaling of the image relative to the origin point of the current viewport (in millipoints)- Throws:
IOException
- if an I/O error occurs
-
createDataObjectInfo
Creates the data object information object- Specified by:
createDataObjectInfo
in classAFPImageHandler
- Returns:
- the data object information object
-
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
