org.apache.fop.render.pdf.PDFImageHandlerGraphics2D
PDFImageHandler implementation which handles Graphics2D images.

PDFImageHandlerGraphics2D()
|
Method Summary | |
PDFXObject |
generateImage(RendererContext context,
org.apache.xmlgraphics.image.loader.Image image,
java.awt.Point origin,
java.awt.Rectangle pos)
Generates the PDF objects for the given Image instance. If the handler generates
an XObject, it shall return it or otherwise return null. A generated XObject shall be
placed in the current viewport according to the two parameters "origin" and "pos". |
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. |
java.lang.Class |
getSupportedImageClass()
Returns the Class subclass supported by this instance. |
org.apache.xmlgraphics.image.loader.ImageFlavor[] |
getSupportedImageFlavors()
Returns the ImageFlavor s supported by this instance |
void |
handleImage(RenderingContext context,
org.apache.xmlgraphics.image.loader.Image image,
java.awt.Rectangle pos)
Handles the given Image instance painting it at the indicated position in the
output format being generated. |
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. |
