Method Detail

generateImage

public PDFXObject generateImage(RendererContext context,
                                org.apache.xmlgraphics.image.loader.Image image,
                                java.awt.Point origin,
                                java.awt.Rectangle pos)
                         throws java.io.IOException
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".

Specified by:
generateImage in interface PDFImageHandler
Parameters:
context - the PDF renderer context
image - the image to be handled
origin - the current position in the current viewport (in millipoints)
pos - the position and scaling of the image relative to the origin point (in millipoints)
Returns:
the generated XObject or null if no XObject was generated
Throws:
java.io.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 for the PDF renderer. The built-in handlers use priorities between 100 and 999.

Specified by:
getPriority in interface PDFImageHandler
Returns:
a positive integer (>0) indicating the priority

getSupportedImageClass

public java.lang.Class getSupportedImageClass()
Returns the Image subclass supported by this instance.

Specified by:
getSupportedImageClass in interface PDFImageHandler
Returns:
the Image type

getSupportedImageFlavors

public org.apache.xmlgraphics.image.loader.ImageFlavor[] getSupportedImageFlavors()
Returns the ImageFlavors supported by this instance

Specified by:
getSupportedImageFlavors in interface PDFImageHandler
Returns:
the supported image flavors
