Method Detail

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 class AbstractAFPImageHandlerRawStream

Parameters:

dataObjectInfo - the image object info being built

image - the image being processed

handleImage

public void handleImage(RenderingContext context,
                        org.apache.xmlgraphics.image.loader.Image image,
                        java.awt.Rectangle pos)
                 throws java.io.IOException

Handles the given Image instance painting it at the indicated position in the output format being generated.

Specified by:

handleImage in interface ImageHandler

Overrides:

handleImage in class AbstractAFPImageHandlerRawStream

Parameters:

context - the rendering context

image - the image to be handled

pos - the position and scaling of the image relative to the origin point of the current viewport (in millipoints)

Throws:

java.io.IOException - if an I/O error occurs

createDataObjectInfo

protected AFPDataObjectInfo createDataObjectInfo()

Creates the data object information object

Specified by:

createDataObjectInfo in class AFPImageHandler

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

public java.lang.Class getSupportedImageClass()

Returns the Class subclass supported by this instance.

Returns:

the image Class type

getSupportedImageFlavors

public org.apache.xmlgraphics.image.loader.ImageFlavor[] getSupportedImageFlavors()

Returns the ImageFlavors 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 of ImageXMLDOM, 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 context

image - 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
