Method Detail

getConfiguredGraphics

public Graphics getConfiguredGraphics(OutputStream os,
                                      Component printTarget)
                               throws IOException

The method returns a graphics context which has been properly configured based on the chosen options in the options panel. This method is responsible for interrogating the options panel to discover what these options are.

IOException

getConfiguredGraphics

public Graphics getConfiguredGraphics(File file,
                                      Component printTarget)
                               throws IOException

The method returns a graphics context which has been properly configured based on the chosen options in the options panel. This method is responsible for interrogating the options panel to discover what these options are.

IOException

done

public void done()
          throws IOException

A method to indicate that the export has finished. If the implementation needs information to finish the export, the implementation must save the necessary information from the getConfiguredGraphics call.

IOException

isMultipageCapable

public boolean isMultipageCapable()

Returns true if this ExportFileType can handle multipage output.

getThumbnailSize

public int getThumbnailSize()

Returns the value of the long side of the thumbnail is desired. -1 indicates that no thumbnail should be given to MultipageDocument.openPage().
