• OptimizationOptions

  public OptimizationOptions()

Method Detail

• getLinkDuplcateStreams

  public final boolean getLinkDuplcateStreams()

  If this flag is set to true, Resource streams will be analyzed. If duplicate streams are found (i.e. if stream contents is equal), then thes streams will be stored as one object. This allows to decrease document size in some cases (for example, when same document was concatenedted multiple times).

  Returns:

  boolean value

• setLinkDuplcateStreams

  public final void setLinkDuplcateStreams(boolean value)

  If this flag is set to true, Resource streams will be analyzed. If duplicate streams are found (i.e. if stream contents is equal), then thes streams will be stored as one object. This allows to decrease document size in some cases (for example, when same document was concatenedted multiple times).

  Parameters:

  value - boolean value

• getAllowReusePageContent

  public final boolean getAllowReusePageContent()

  If true page contents will be reused when document is optimized for equal pages.

  Returns:

  boolean value

• setAllowReusePageContent

  public final void setAllowReusePageContent(boolean value)

  If true page contents will be reused when document is optimized for equal pages.

  Parameters:

  value - boolean value

• getRemoveUnusedStreams

  public final boolean getRemoveUnusedStreams()

  If this flag set to true, every resource is checked on it's usage. If resource is never used, then resources is removed. This may decrease document size for example when pages were extracted from document.

  Returns:

  boolean value

• setRemoveUnusedStreams

  public final void setRemoveUnusedStreams(boolean value)

  If this flag set to true, every resource is checked on it's usage. If resource is never used, then resources is removed. This may decrease document size for example when pages were extracted from document.

  Parameters:

  value - boolean value

• getRemoveUnusedObjects

  public final boolean getRemoveUnusedObjects()

  If this flag is set to true, all document objects will be checked and unused objects (i.e. objects which does not have any reference) are removed from document.

  Returns:

  boolean value

• setRemoveUnusedObjects

  public final void setRemoveUnusedObjects(boolean value)

  If this flag is set to true, all document objects will be checked and unused objects (i.e. objects which does not have any reference) are removed from document.

  Parameters:

  value - boolean value
