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. The built-in handlers use priorities between 100 and 999.

Specified by:

getPriority in interface ImageHandlerBase

Returns:

a positive integer (>0) indicating the priority

getSupportedImageClass

public java.lang.Class getSupportedImageClass()

Returns the Class subclass supported by this instance.

Specified by:

getSupportedImageClass in interface ImageHandlerBase

Returns:

the image Class type

getSupportedImageFlavors

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

Returns the ImageFlavors supported by this instance

Specified by:

getSupportedImageFlavors in interface ImageHandlerBase

Returns:

the supported image flavors
