Detailed Description

Base class for an Iop which strongly wishes to output planar data, possibly with striping. This implements PlanarI to hint as to how the data should be accessed, and adds ImagePlaneCache (privately) to provide a cache.

Member Function Documentation

virtual void DD::Image::PlanarIop::getRequests ( const Box box,
const ChannelSet channels,
int  count,
RequestOutput reqData 
) const
inlinevirtual

The function _request() on Iops is eventually going to be deprecated, because it is stateful.

For PlanarIops you should never override it. Instead, please implement this getRequests() function. It should place the regions to be requested to the RequestOutput passed in. This will be used for more complex render management in future.

Overrides of this function should have no side-effects other than filling in reqData.

References DD::Image::RequestOutput::request().

virtual void DD::Image::PlanarIop::renderStripe ( ImagePlane plane)
pure virtual

This is the actual rendering function that subclasses should implement.

The subclass is responsible for filling plane to the extent of its bbox and channels. It is guaranteed that the plane will never have more than 4 channels, and that its bounding box will be one of those that getStripeBox() returns. The ChannelSet will be a full layer, but no more than one layer. It might be packed or not depending upon the results of negotiation.

It will only be called for channels in the out_channels as set by _validate.

Implemented in DD::Image::Read.

DD::Image::ChannelSet DD::Image::PlanarIop::expandChannelsToFullPlanes ( const ChannelSet channelSet)

This expands a channel set to include all channels in the planes that contain any of the channels passed in, not just those that have been requested.

DD::Image::PlanarI::PlaneSet DD::Image::PlanarIop::expandToFullPlanes ( ChannelSet  channelSet)

This expands a channel set to include all channels in the planes that contain any of the channels passed in, not just those that have been requested, and returns them as a plane set.

void DD::Image::PlanarIop::EnablePlaneInterests ( )
static

Function to be called by Nuke before the image is rendered (e.g. in Viewer_Image and Execute) to enable plane interests so that the planar cache is not cleared while rows are reading from it.

void DD::Image::PlanarIop::DisablePlaneInterests ( )
static

Function to be called by Nuke after the image is rendered to make sure that the planar cache's memory can be released (e.g. in Viewer_Image and Execute).

void DD::Image::PlanarIop::doFetchPlane ( ImagePlane plane)
overrideprotectedvirtual

Private implementation of this Iop function. Calls renderStripe to do actual work, which is the one that subclasses should implement.

Reimplemented from DD::Image::Iop.

Reimplemented in DD::Image::Read.

size_t DD::Image::PlanarIop::getStripeCount ( ) const
overrideprotectedvirtual

Implementation of this function based on useStripes() and stripeHeight().

calculate the number of stripes. if striping is used this will be the height of the bbox divided by the stripe height (rounded up)

Implements DD::Image::PlanarI.

References DD::Image::IopInfoOwner::h(), DD::Image::IopInfoOwner::info(), stripeHeight(), and useStripes().

DD::Image::Box DD::Image::PlanarIop::getStripeBox ( int  idx) const
overrideprotectedvirtual

Implementation of these functions based on useStripes() and stripeHeight().

calculate the size of stripe /idx/.

the last stripe shouldn't go any higher than the top of the bbox (this is not a problem for the first stripe, as it starts at the bottom of the bbox always)

Implements DD::Image::PlanarI.
