  \brief    Data class containing the relevant additional informations needed in
Toshihiro Shimizu 890ddd

Toshihiro Shimizu 890ddd
Shinya Kitaoka 120a6e
  \details  This class stores most of the data required by Toonz and single fxs
Shinya Kitaoka 120a6e
  to
Shinya Kitaoka 120a6e
            perform a render. While a good part of this data group is used
Shinya Kitaoka 120a6e
  internally
Shinya Kitaoka 120a6e
            by Toonz to deal with global aspects of a rendering process, another
Shinya Kitaoka 120a6e
  part
Toshihiro Shimizu 890ddd
            must be actively referenced when rendering an fx.
Toshihiro Shimizu 890ddd
Shinya Kitaoka 120a6e
            The most important member of this class is \p m_affine, which
Shinya Kitaoka 120a6e
  specifies
Shinya Kitaoka 120a6e
            the affine transform that must be applied by an fx if it were to
Shinya Kitaoka 120a6e
  render
Toshihiro Shimizu 890ddd
            on the default reference.

Shinya Kitaoka 120a6e
/*!
Shinya Kitaoka 120a6e
  A standard Toonz Fx is roughly composed of 2 parts: one providing the
Shinya Kitaoka 120a6e
necessary
Shinya Kitaoka 120a6e
  interface for access by a GUI interface (covered by the TFx class, which this
Shinya Kitaoka 120a6e
class
Toshihiro Shimizu 890ddd
  inherits), the other for the actual computation of the fx - which is the focus
Toshihiro Shimizu 890ddd
  of the TRasterFx interface.
Toshihiro Shimizu 890ddd
\n\n
Shinya Kitaoka 120a6e
  So, the essential part of this class lies in the compute() and doCompute()
Shinya Kitaoka 120a6e
methods that
Shinya Kitaoka 120a6e
  are invoked to perform an fx computation. The former method is the publicly
Shinya Kitaoka 120a6e
accessed one, while
Shinya Kitaoka 120a6e
  the latter is the one that fx writers must reimplement to supply their
Shinya Kitaoka 120a6e
rendering code.
Toshihiro Shimizu 890ddd
\n
Shinya Kitaoka 120a6e
  The allocateAndCompute() method can be used to automatically allocate the tile
Shinya Kitaoka 120a6e
to be rendered
Toshihiro Shimizu 890ddd
  right before invoking compute().
Toshihiro Shimizu 890ddd
\n\n
Shinya Kitaoka 120a6e
  The dryCompute() / doDryCompute() methods are required by Toonz to perform
Shinya Kitaoka 120a6e
predictive caching
Shinya Kitaoka 120a6e
  in order to minimize needless recomputations of the same fx. Fx writers must
Shinya Kitaoka 120a6e
reimplement
Shinya Kitaoka 120a6e
  doDryCompute() to mimic the behaviour of doCompute() in terms of compute()
Shinya Kitaoka 120a6e
invocations for children
Toshihiro Shimizu 890ddd
  fx nodes. Those compute() invocations must be replaced with dryCompute().
Toshihiro Shimizu 890ddd
\n\n
Shinya Kitaoka 120a6e
  The getBBox() / doGetBBox() methods are used to obtain the geometry of the
Shinya Kitaoka 120a6e
maximal output that an
Shinya Kitaoka 120a6e
  fx can produce with similar inputs to compute(). Again, doCompute() is the
Shinya Kitaoka 120a6e
method to reimplement
Shinya Kitaoka 120a6e
  by subclasses. Observe that, unlike doCompute() and doDryCompute(), in this
Shinya Kitaoka 120a6e
case the affine supplied
Shinya Kitaoka 120a6e
  with the render settings must be \b ignored (see the method itself for further
Shinya Kitaoka 120a6e
details).
Toshihiro Shimizu 890ddd
\n\n
Shinya Kitaoka 120a6e
  The canHandle() / handledAffine() methods are used by the compute() function
Shinya Kitaoka 120a6e
to separate the part of
Shinya Kitaoka 120a6e
  an affine that the doCompute() can apply to the result on its own from the
Shinya Kitaoka 120a6e
rest (which is automatically
Toshihiro Shimizu 890ddd
  applied on the fx result using TRasterFx::applyAffine() ).
Shinya Kitaoka 120a6e
  Note that every Toonz fx should be able to handle at least the scale part of
Shinya Kitaoka 120a6e
an affine (applying
Shinya Kitaoka 120a6e
  TRasterFx::applyAffine() on image enlargements typically hampers image
Shinya Kitaoka 120a6e
quality).
Toshihiro Shimizu 890ddd
\n\n
Shinya Kitaoka 120a6e
  Further methods whose reimplementation depends on the fx itself are
Shinya Kitaoka 120a6e
getAlias(), which must return
Shinya Kitaoka 120a6e
  a string uniquely descripting a rendered object, and getMemoryRequirement() to
Shinya Kitaoka 120a6e
declare the amount of
Toshihiro Shimizu 890ddd
  memory that will be used by the fx.
