Detailed Description

Return an image from the outside world. The image is identified by the filename (which may just be a string interpreted by one of the reader implementations and not an actual file on the disk), and by the frame() if it is a movie file.

If the filename is null a black frame of the expected_format() (or video if no format is given) is produced. This is done so that a new Read in Nuke will not produce an error.

All the work is done by the various subclasses of Reader. Read just chooses what subclass to instantiate and returns the output from it, and correctly destroys and instantiates new ones as needed.

void Read::make_format ( const char * fileName )

protected

Open the file and create the Reader object.

References DD::Image::ReaderDescription::names.

const MetaData::Bundle & Read::_fetchMetaData ( const char * key )

protectedvirtual

We can't return this directly, because the Reader might get deleted (thus invalidating the reference) when the Read is closed.

So, let us make a local copy to store it in, which is guaranteed to be around for as long as we need it. We can put some non-reader specific things in this, also.

Reimplemented from DD::Image::Op.

References DD::Image::ReaderDescription::label.

void Read::_validate ( bool for_real )

protectedvirtual

validate() will destroy any previous Reader and open a new one if the filename has changed or the version number has changed (the version number is incremented by the reload button).

After opening the file, it copies the info_ from the Reader object. This will have been initialized with expected_first_frame(), expected_last_frame(), expected_format(), and expected_full_size_format(), but the Reader subclass may have changed this information.

For Nuke, this may be called with for_real set to false. In this case it does not try to open the file. Instead it assumes everything is at the expected settings. Anything that actually needs the data will open the file.

Reimplemented from DD::Image::Iop.

void Read::_open ( )

Calls open() on the reader object.

void Read::engine	(	int	y,
		int	x,
		int	r,
		ChannelMask	channels,
		Row &	row

protectedvirtual

Calls Reader::engine()

bool Read::useStripes ( ) const

size_t Read::stripeHeight ( ) const

protectedvirtual

implementation of PlanarIop::stripeHeight()

PlanarI::PackedPreference Read::packedPreference ( ) const

protectedvirtual

implementation of PlanarIop::packedPreference()

void Read::renderStripe ( ImagePlane & imagePlane )

protectedvirtual

implementation of PlanarIop::renderStripe

Implements DD::Image::PlanarIop.

References DD::Image::ImagePlane::fillChannel(), and DD::Image::ImagePlane::makeWritable().

void Read::doFetchPlane ( ImagePlane & imagePlane )

protectedvirtual

implementation of Iop::packedPreference(). Calls Iop::doFetchPlane() or PlanarIop::doFetchPlane() depending on whether the reader supports planar.

Reimplemented from DD::Image::PlanarIop.

PlanarI * Read::getPlanarI ( )

protectedvirtual

implementation of PlanarIop::getPlanarI

Reimplemented from DD::Image::PlanarIop.

PlanarI::PlaneID Read::getPlaneFromChannel ( Channel chan )

protectedvirtual

implementation of PlanarI::getPlaneFromChannel

this is only defined for channels that the reader actually supports, otherwise return plane consisting of individual layer.

Reimplemented from DD::Image::PlanarI.

void Read::_close ( )

protectedvirtual

Call this to close any current file. This will free up resources. Nuke calls this automatically after a timeout.

open() will reopen the file, but it assumes the file is the same one. You must call invalidate() if there is a possibility the existence, readability, or dimensions of the file has changed.

Reimplemented from DD::Image::Iop.

const Format * DD::Image::Read::expected_full_size_format ( ) const

inline

This is the Format the Read will output as full_size_format(). If it is NULL or is equal to expected_read_format() then the format() is returned.

const Format * DD::Image::Read::expected_format ( ) const

inline

If not NULL then this is the proxyfied version of the expected_full_size_format and will be used as the output format(). If this is NULL then the read format is used and you better not try to set any proxy scaling.

const Format * DD::Image::Read::expected_read_format ( ) const

inline

This is the format to assume file is in if it has the correct dimensions. If the dimensions are wrong then Format::find() is used to locate or create a correct format, but the pixel_aspect from this format is used as a hint.

If this is NULL (the default value) then Format::find() is always called with a pixel aspect of 1.

void Read::append ( Hash & hash )

virtual

Indicate that the frame number, view, autoAlpha, and LUT may affect the output.

Reimplemented from DD::Image::Op.

References DD::Image::ValueStuffI::get_value(), DD::Image::Op::knob(), and DD::Image::root_real_fps.

void Read::setIgnoreCachedErrors ( bool ignoreCachedErrors )

Setter for ignoreCachedErrors flag which is used by the renderFrames() function to force-invalidate read ops which depend on previous writes in the op tree.

void Read::expectedFrameRange	(	int	first,
		int	last
	)

virtual

Set the frame range returned if the image file itself does not contain a frame range.

Implements DD::Image::ReadFileKnobOwner.

void DD::Image::Read::colorspace ( int v )

inline

Make the Reader use LUT::builtin(v) to convert the data, unless v is zero in which case the Reader chooses the LUT itself (for most Readers the default LUT is sRGB). Zero is the default value.

void DD::Image::Read::raw ( bool v )

inline

Sets the LUT to LUT::LINEAR (overriding the colorspace() setting). Some Reader types may examine this setting and use it to turn off other processing, such as conversion from YUV space.

void DD::Image::Read::premult ( bool v )

inline

Indicates that data should be divided by the alpha channel before being run through the LUT, and then multiplied again afterwards. This will convert data that was premultiplied in the file's colorspace into data that is premultiplied in linear colorspace.

This makes a difference if the LUT is anything other than LUT::LINEAR for any pixels where the alpha is greater than zero and less than one.

void DD::Image::Read::output_type ( int v )

inlinevirtual

Sets exactly what is in the pixels that the Read produces. This is used by Nuke to produce results with the correct size and channels for missing frames, such as out-of-range frame numbers, or missing files in the middle of the range. This is done by setting the filename to an actual existing file, but using this to make the read produce black or a checkerboard.

IMAGE returns the data from the file.
BLACK returns zero in all channels and sets the bounding box to 1x1.
CHECKERBOARD produces a box pattern for all channels and sets the bounding box to the format.

Implements DD::Image::ReadFileKnobOwner.

void DD::Image::Read::force_near_frame ( bool b )

inlinevirtual

Force the read node to use near frame in case of error !

Implements DD::Image::ReadFileKnobOwner.

void DD::Image::Read::force_format ( bool b )

inline

Force the read node to output at the expected format !
