handleImage
public void handleImage(RenderingContext context, org.apache.xmlgraphics.image.loader.Image image, Rectangle pos) throws IOException Handles the givenImageinstance painting it at the indicated position in the output format being generated.- Specified by:
handleImagein interfaceImageHandler- 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
-
generateForm
public void generateForm(RenderingContext context, org.apache.xmlgraphics.image.loader.Image image, PSImageFormResource form) throws IOException Generates a PostScript form for the givenImageinstance.- Specified by:
generateFormin interfacePSImageHandler- Parameters:
context- the rendering contextimage- the image to be handledform- the associated form resource- Throws:
IOException- if an I/O error occurs
-
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.- Specified by:
getPriorityin interfaceImageHandlerBase- Returns:
- a positive integer (>0) indicating the priority
-
getSupportedImageClass
Returns theClasssubclass supported by this instance.- Specified by:
getSupportedImageClassin interfaceImageHandlerBase- Returns:
- the image Class type
-
getSupportedImageFlavors
public org.apache.xmlgraphics.image.loader.ImageFlavor[] getSupportedImageFlavors()Returns theImageFlavors supported by this instance- Specified by:
getSupportedImageFlavorsin interfaceImageHandlerBase- 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.- Specified by:
isCompatiblein interfaceImageHandler- 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
