Detailed Description

All functions and classes that are used for image processing by Nuke Plugins are in this namespace. Some utility and cross-platform compatibility functions are not in this namespace.

Typedef Documentation

typedef unsigned DD::Image::GeometryMask

Geometry part mask. Each bit represents a logical geometric component.

typedef SignalLock DD::Image::SlowSignalLock

This is for back compatibility only

Enumeration Type Documentation

enum DD::Image::AttribType

Attribute data type enumerations.

Enumerator:

INVALID_ATTRIB	Data type not set.
FLOAT_ATTRIB	1 float
VECTOR2_ATTRIB	Vector2(2 floats)
VECTOR3_ATTRIB	Vector3(3 floats)

enum DD::Image::Channel

Channel ID numbers. These are used to index arrays of pixel data, such as in the DD::Image::Row object.

A plugin can use these pre-defined ones. Nuke will also create new ones that are outside this set. DD::Image::getName() will return a string name of these.

A plugin can create channels by using DD::Image::getChannel(). DD::Image::findChannel() looks up channels by name but without creating them.

See also the class DD::Image::ChannelSet.

Enumerator:

Chan_U	used mostly for 2d ops, 1/distance (so, 0 = infinitely far away)
Chan_DeepBack	used mostly for deep ops, distance to front of sample (0=at camera, inf=infinitely far away)
Chan_Mask_PlanarTrack	used mostly for deep ops, distance to front of sample (0=at camera, inf=infinitely far away)

enum DD::Image::ChannelSetInit

Bitmasks of various combinations of the predefined Channel numbers. These values can be used in most places a ChannelSet is expected. They will be cast to ChannelSet or used directly by the code.

Enumerator:

Mask_All

Special value that makes the ChannelSet contain all possible channels.

Enumerator:

Mask_Px	Point x.
Mask_Py	Point y.

Mask_Attributes	Attribute list.

enum DD::Image::RenderMode

Value for render_mode.

enum Display3DMode [related, inherited]

Value for GeoOp::display3d() and ViewerContext::display3d()

enum DD::Image::LookupCurvesType

Type for the lookup curves editor. Mostly affects background and framing. On the hue types the first and last keyframes will be synchronised.

anonymous enum

Transform-space enumerations for shaders. These numbers are used by the MatrixArray class to index the in/out space parameters.

Enumerator:

LOCAL_SPACE	Point in locally defined space.

enum DD::Image::MotionVectorType

Scene motion vector types.

Enumerator:

eDisableMotionVector	the motion vector is disable
eClassicMotionVector	classic and old way to do motion vector
eVelocityMotionVector	store velocity in motion vector channel
eDistanceMotionVector	store distance in motion vector channel

enum DD::Image::StringExpandFlags

"expand" the string by replacing tcl portions of the string with the final text. Returns true if successful, false otherwise.

This function is not thread-safe.

"[command]" is replaced with the result of executing that command, and "$variable" is replaced with the tcl variable.

The flags controls what is replaced. The following substitutions are done:

If the flag eStringExpandFilename is set, a leading "~/" is replaced by the value of $env(HOME), and a leading "~foo" is replaced by a guess of the user foo's home directory done by replacing the end of $env(HOME) (nuke does not bother with the passwd file). And the result is passed through filename_fix, if the command is defined.

If the flag eStringExpandFileNumber is set, a nd and ### sequences are replaced by the frame number from the ScriptContext argument, and V and v are replaced with the name and initial of the view.

"\x" (where x is any character including backslash) is replaced by "x". However the backslash prevents x from being interpreted in any way, so you can get square brackets or %% or other characters into the output.

enum DD::Image::DrawHandleType

The types of drawing handle that Nuke recognises. Geometry handles are always drawn, regardless of the selection mode; all other types are only drawn when the Nuke viewer is in the appropriate selection mode. The default mode is node selection, which corresponds to the original Nuke behaviour.

enum DD::Image::SelectionOptions3D

Selection options for the 3D viewer. These options appear in the same menu as the Selection modes above, so it's important that the first option's ID is

anonymous enum [related, inherited]

Value for ViewerContext::what_to_draw(). This is a bunch of checkmarks on the viewer. The viewer will implement some of these (such as transparency or lighting) by initializing the OpenGL state, but it may still be useful to check if they are off.

Enumerator:

SHOW_POINT_NORMALS	draw point normals
SHOW_VERTEX_NUM	draw vertex normals
SHOW_VERTEX_NORMALS	draw vertex normals
SHOW_PRIMITIVE_NUM	draw primitive number
SHOW_PRIMITIVE_NORMAL	draw primitive normal
SHOW_BBOX	draw bounding box around things
SHOW_TRANSPARENCY	transparency checkmark from viewer
SHOW_LIGHTING	lighting checkmark from viewer

anonymous enum [related, inherited]

Function Documentation

void DD::Image::SetValueProvider	(	Knob_Callback	f,
		ArrayKnobI::ValueProvider *	valueProvider
	)

set the valueProvider on the most recently made Knob. if f.makeKnobs() is not true, or the that knob is not an ArrayKnobI, is a no-op. For calling from knobs(Knob_Callback) like calls to SetFlags()

void DD::Image::incr ( Channel & c ) [inline]

Adds one to the Channel and returns it.

Referenced by DD::Image::Row::offset().

std::ostream & DD::Image::operator<<	(	std::ostream &	o,
		Channel	channel
	)

This prints getName(channel), but prints the number if the name is null.

References getName().

Channel DD::Image::getChannel	(	const char *	name,
		bool	sort = `true`
	)

Find or create a channel with this name. Plugins can call this to get the number for any channels they want to output.

For instance if you output something called "shadow" for each pixel, you may want to call this with "shadow" as an argument in order to get what channel to write to. All calls to get "shadow" will return the same number. If you output an xyz triplet called "position" you may want to call this with "position.x", "position.y", and "position.z".

Text before the last period is used to create or find the layer. If there is no period, it makes a layer called "other" (this may change in future versions). If sort is true, then the channel is insertion-sorted into the layer so that r,g,b,a are first and then the rest of the channels are in alphabetical order. If sort is false then the channel is appended to the end of the layer. (this sorting was needed because the exr library produces the channels in a random order due to the use of a hash table).

Referenced by DD::Image::Iop::channel().

Channel DD::Image::findChannel ( const char * name )

Find a channel with this name. Plugins can call this to get the number for any channels they want to output.

const char * DD::Image::getName ( Channel channel )

Returns a string name to print for the channel, or NULL if it cannot figure it out. This is a full "layer.chan" name.

Referenced by DD::Image::Iop::channel_name(), operator<<(), and DD::Image::Memory::register_allocator().

const char * DD::Image::getLayerName ( Channel channel )

Returns the name of the layer this channel belongs to, or NULL if it can't find a layer.

unsigned DD::Image::colourIndex	(	Channel	channel,
		const char *	layer = `0`
	)

Returns 0 if this channel is "red", 1 if it is "green", 2 if it is "blue", and 3 for all other possibilities.

Referenced by DD::Image::DrawIop::pixel_engine().

Channel DD::Image::brother	(	Channel	channel,
		unsigned	index
	)

Return a channel such that colourIndex(n) returns the given index, and it belongs to the same layer as channel. This is used to find the related colours. You can also use this to find all the channels in a layer by incrementing the index until this returns Chan_Black.

Returns Chan_Black if no such channel exists.

Also see DD::Image::ChannelSet::addBrothers().

bool DD::Image::compareChannels	(	Channel	a,
		Channel	b
	)

Compares two channels to determine ordering based on purpose. For example, a channel with purpose Chan_Red will order before one with purpose Chan_Green, regardless of the actual channel map ordering.

const Version& DD::Image::version ( ) [inline]

Returns a structure that you can query to get the DDImage version in various forms, such as text or numbers.

Referenced by DD::Image::GeoOp::synchronize_cache().

const Version& DD::Image::applicationVersion ( ) [inline]

Returns a structure that you can query to get the Nuke version in various forms. This does not work if DDImage is not being used by Nuke.

double DD::Image::scriptVersion ( ) [inline]

This is a version of Nuke that was used to write the currently loading script, encoded as M.mr where M is the major number and m is the minor, and r is a revision. If a script is not being currently loaded this is set to applicationVersion().majorMinorReleaseDouble() which is the number that will be saved when a script is written. This can be used to preset back-compatibility knobs in an Op.

void DD::Image::CombineOverlappingSamples	(	const ChannelMap &	channels,
		const DeepPixel &	deepPixel,
		DeepSampleVector &	pixels
	)

combines overlapping samples from within /deepPixel/ into a number of non-overlapping samples, output in /pixels/ will omit any samples after a sample with alpha 1.

bool DD::Image::RenameTempToFinal	(	const char *	lpTempName,
		const char *	lpFinalName,
		Op *	lpOp
	)

Renames a temporary file to its final name. On failure, it sets an appropriate error message on the supplied op.

Returns:: True iff the rename succeeded. If false, an error message will be set.

const AttribContext* DD::Image::GetGeoInfoAttribContext	(	const GeoInfo *	info,
		const char *	attribName,
		AttribType	attribType
	)		`[inline]`

Get a valid and not empty attribute context from GeoInfo

References DD::Image::AttribContext::name, and DD::Image::AttribContext::type.

void DD::Image::glColor ( unsigned c )

Set the current OpenGL color to a color specified by the bytes of the unsigned value. The highest byte is red, the next green, then blue, then alpha. For instance 0xff00ff00 is purple (red+blue). This is the same form the Nuke and fltk use to identify GUI colors. Currently the alpha value is ignored.

	)

Call glVertex2f with points on a 2-D bezier curve. x,y are the initial point, which is not drawn (this is done so several curves join together, you should draw the point yourself for the first curve in the sequence. The curve goes to x3,y3. x1,y1 and x2,y2 are the bezier handles.

Enough points are drawn so that the error of the curve is less than one pixel anywhere and the straight edges should not be visible. To to this it needs to know how big one unit is in pixels, this can be passed as scale.

This should not be used for curves that are way bigger than the viewport. The algorithim would normally divide the line into millions of pieces and waste a huge amount of time drawing the clipped pieces. This version does a maximum of 100 segments, so the machine does not lock up, but the result is then inaccurate.

void DD::Image::gl_drawTextTopLeftOrthogonal	(	const std::string &	text,

draws text in the top left of the ViewerWindow tied to the ViewerContext. By default draws it in red text, if you want another colour, set redColour to false and set the colour before calling this then pop the attribute after calling this.

void DD::Image::SetFlags	(	Knob_Callback	f,
		Knob::FlagMask	n
	)

In an Op::knobs() function, this turns on some flags on the previous knob. The initial setting of the flags is done by the knob-creating function, depending on the type of knob and the arguments to that function, but you can modify it with this. Warning: not all flag combinations are supported!

Values that work for any knob:

Knob::DISABLED Set by disable(), cleared by enable().
Knob::NO_ANIMATION Prevent the value from being animated. This removes any animation or view buttons, and it stops tcl expressions from being evaluated in string knobs, and may make it ignore attempts to set expressions or key frames (nyi).
Knob::HIDE_ANIMATION_AND_VIEWS Prevent animation and view buttons from being displayed. Animation is still possible, unless NO_ANIMATION is specified of course.
Knob::DO_NOT_WRITE Don't ever save this knob to a script (including copy & paste!)
Knob::INVISIBLE The knob does not appear in the panels. No widgets are created. This is not the same as hide(), and show() will not undo it!
Knob::RESIZABLE The knob can stretch in the panel so that it fills up all the remaining space in the line. Defaults to true for most of the complex knobs, but off for buttons, checkmarks, and pulldown lists.
Knob::STARTLINE This knob starts a new row in the panel. The default is true unless a zero-length (not NULL) string is passed as the label. Currently the default is false for checkmarks and buttons but this may change in future versions.
Knob::ENDLINE This knob will end a row, acts exactly like STARTLINE was set on the next knob. Set true for divider lines.
Knob::NO_RERENDER This knob does not contribute to the hash value for the op. This should be used on knobs that have no effect on the op's output.
Knob::NO_HANDLES Don't draw anything in the viewer, this is useful if the Op draws it's own indicators.
Knob::HANDLES_ANYWAY makes the handles appear in the viewer when the panel is open even if a different tab is selected.
Knob::HIDDEN Set by hide(), cleared by show().
Knob::NO_UNDO Don't undo/redo any changes to this knob. May be replaced with "output knob" in the future.
Knob::NO_KNOB_CHANGED: Don't bother calling Op::knob_changed() with this knob. This is turned on automatically if the knob_changed() returns false.
Knob::KNOB_CHANGED_ALWAYS will call node()->knob_changed() every time the value of the knob changes. Normally it is only called if the user changes the value with the panel open. This allows you to track all changes to the value. Be careful as knob_changed() will be called without storing the new values into your structure.
Knob::ALWAYS_SAVE save the knob to a script even if not_default() returns false. Deprecated, instead override not_default() and make it return true!
Knob::NODE_KNOB is used by Nuke internally for controls on the DAG appearance such as xpos and ypos.
Knob::MODIFIES_GEOMETRY should be set for any knob that modifies geometry, either by affecting the internal geometry directly or by changing its transform

Values that work for knobs that store numbers:

Knob::MAGNITUDE If there are several numbers, this enables a button to only show a single number, and all are set equal to this number. Default is true for WH_knob() and Color_knob().
Knob::SLIDER Turns on the slider. Currently this only works if the size is 1 or MAGNITUDE is enabled and it is set to single numbers. Defaults to on for most non-integer numerical controls.
Knob::LOG_SLIDER Tick marks on the slider (if enabled with SLIDER) are spaced logarithmically. This is turned on for WH_knob() and Color_knob(), and if the range has both ends greater than zero. If you turn this on and the range passes through zero, the scale is actually the cube root of the number, not the logarithim.
Knob::TINY_SLIDER Modifies SLIDER. The slider is shown as a thin strip underneath the LineEdit/SpinBox.
Knob::STORE_INTEGER Only integer values should be displayed or stored.
Knob::FORCE_RANGE Clamps the value to the range when storing.
Knob::ANGLE Turn on a little widget depicting this number as an angle.
Knob::NO_PROXYSCALE disables proxy scaling for XY or WH knobs. Useful if you just want two numbers called "x" and "y" that are not really a position. You probably also want to do NO_HANDLES.

Values that work for Enumeration_knob():

Knob::SAVE_MENU writes the contents of the menu to the saved script. Useful if your plugin modifies the list of items.

Values that work for BeginGroup():

Knob::CLOSED True for a BeginGroup knob that is closed

Values that work for ChanneSet_knob() and Channel_knob():

Knob::NO_CHECKMARKS Get rid of the individual channel checkmarks.
Knob::NO_ALPHA_PULLDOWN Get rid of the extra pulldown that lets you set the 4th channel to an arbitrary different layer than the first 3.

Values that work for Format_knob():

Knob::PROXY_DEFAULT makes the default value be the root.proxy_format rather than the root.format.

Knob* DD::Image::Obsolete_knob	(	Knob_Callback	f,
		const char *	linkto,
		NAME	name,
		const char *	script
	)		`[inline]`

Obsolete_Knob is used to throw away the values saved in scripts for knobs that are no longer in use. This knob will not be listed in lists of knobs or saved to files. But if you know it's name, scripting language or loading files can still set the knob or query it's value.

linkto, if not null, is the name of a knob to link to. Attempts to set or get information from the knob will instead act on this linked knob. If this is null only from_script() will work, all other calls will produce errors. This is very similar to Link_knob().

script, if this is not null, is a tcl script that is called instead of calling from_script() on the linked-to knob. This script is executed in the context of the node, and the text attempting to be stored into the knob is put in $value.

If both are null then the knob is ignored, attempts to set it are thrown away without any error.

Be careful with the argument order. It is set up to match the Link_knob() arguments and there is some back-compatibility problems.

Knob* DD::Image::WH_knob	(	Knob_Callback	f,
		double *	p,
		NAME	n,
		LABEL	l = `0`
	)		`[inline]`

Stores a width and height. The user can change the slider to two input fields so they can make the width and height different. When stored the horizontal value (the first one) is divided by the incoming format's pixel aspect ratio, so if the user sees equal values the result is square in the viewer. The sizes are also scaled to account for the difference between the full size and proxy formats.

Stores four numbers representing the x, y, right, and top of a rectangle selected by the user. The values are scaled by the current proxy settings. Draws this rectangle on the viewer that the user can manipulate.

The parent is an optional XY_knob() return value. The stored values are then relative to the point stored by that knob, and moving the XY_knob will move the box with it.

Knob* DD::Image::Format_knob	(	Knob_Callback	f,
		FormatPair *	p,
		NAME	n,
		LABEL	l = `0`

User chooses a format, which is stored in p.full_size_format. Also the current proxy scaling is used to produce another format that is stored in p.format.

Normally you should use p.format for any calculations. However since the bottom and top values are rounded to the nearest integer, you may want to use outputContext().to_proxy() on the full_size_format values to get exact vertical positions.

The FormatPair structure also contains space for making the p.format if necessary.

		int	np,
		NAME	n,
		LABEL	l = `0`
	)		`[inline]`

Store np numbers, but show a single slider with multiple moving slider handles. Values will always be in sorted because the user cannnot move the sliders through each other.

Knob* DD::Image::Transform2d_knob	(	Knob_Callback	f,
		Matrix4 *	p,
		NAME	n,
		int	type = `0`
	)		`[inline]`

This knob stores into a Matrix4 a 2-D transformation (although a Matrix4 is 4x4, this will only set 6 a00,a01,a03,a10,a11,a13 to values other than the identity). The user is presented with a "transform jack" in the viewer.

This creates named child knobs. If the name of the knob ends with "_" then these names are instead appended to this overall name, which allows more than one of these to be used in a node.

type modifies how the transform knob works. Known types are:

TRANSFORM (0) = Used by Transform operator. Initializes to the identity and initializes the center to put itself in the middle of the image. The stored matrix will transform pixel positions.

TO_PROXY = Same as TRANSFORM but when it calculates the matrix when Nuke is in proxy mode, it also stores the conversion from full-size to proxy format. This can be used by a knob like the Bezier that wants to store a set of x/y positions specified by the user.

POSITIONER = Used to place objects, such as Text, where location 0,0 is of some importance to the user. Hides the "center" control from the user (though the user can still move it with ctrl+drag) The passed matrix is used to initialize the transform. Currently only scale and translate is deduced from it.

POSITIONER|TO_PROXY = Does both.

T2D_GAUGE adds a little angular handle that outputs a value between 0 and 1 in bottom right corner of the matrix. Be sure to reset this value to 1 before using the matrix! Example use is transparency in the 'wipe' UI of the viewer.

Knob* DD::Image::LookupCurves_knob	(	Knob_Callback	f,
		LookupCurves *	p,
		DD::Image::LookupCurvesType	type,

double DD::Image::noise	(	double	x,

	)

3D Perlin noise function.

Unlike some shader libraries, this produces a signed range centered on zero. The absolute maximum range is from -1.0 to 1.0. Doing (noise(x,y,z)+1)/2 will return values that are used by some other libraries. This produces zero at all integers, so you should rotate the coordinates somewhat (add a fraction of y and z to x, etc) if you want to use this for random number generation.

This uses a compiled random table and thus will produce exactly the same results on all platforms for the same xyz values.

int DD::Image::plugin_count ( )

Return how many plugins have been loaded. This is incremented by every successful plugin_find().

const char * DD::Image::plugin_name ( )

Return the name of the plugin being currently loaded. This is set when reading binary or tcl plugins. A blank string is returned if no such plugin is currently being loaded. The directory of this name will affect the locations searched by plugin_find().

Referenced by plugin_find(), and plugin_load().

const char * DD::Image::plugin_name ( int n )

Return the filename of the Nth plugin that was found.

const char * DD::Image::plugin_find	(	const char *	name,
		const char const	extensions = `0`
	)

Find and return the filename of a plugin. If the file is found, the full filename is copied to permanent storage and that permanent copy is returned. If the file is not found zero is returned.

If name contains any slashes, then it is expanded relative to the directory that is in plugin_name(), and that single filename (with any possible extensions) is checked. Note that only forward slashes work.

Otherwise every single directory in getPluginPath() is looked into.

extensions is an optional null-terminated list of filename extensions to try. These should start with a period. Each of them is added to the filename in each directory and the first match is returned. This is *only* done if name does not contain a period after the last slash. If you need to know which one was used, look at the end of the returned string (I don't return the index in order to force calling code to check extensions that are supplied in the plugin name).

The extension ".osx.bundle" is handled specially, if it is matched a whole lot more data is tacked on in order to produce the actual name of the shared object file that the plugin really is in.

const char * DD::Image::plugin_load	(	const char *	name,
		const char *	altname = `NULL`
	)

load a plugin with the basename 'name' (or 'altname' if specified and nothing by name can be found)

Try to load a shared-object or tcl plugin.

plugin_find() is done with the passed name. This means that if the name does not have any slashes in it, it is looked for in every directory in getPluginPath(). If it does have a slash in it, it is tried in one location, relative the the location of the current plugin if it does not start with slash.

If there is no period in the name after the last slash, then it tries the following extensions:

".$plugin_ext" (".so", ".dylib", ".dll" etc depending on platform). This is a compiled plugin. These extensions allow plugins compiled for different platforms to coexist in the same directory.
".tcl" and ".gizmo". Extensions for interpreted nuke scripts

If the plugin is found, it is loaded. If the resulting filename ends in ".tcl" or ".gizmo" then plugin_interpret() is called. Otherwise plugin_binary() is called. The filename found is returned. If the plugin fails to load due to some error you can retrieve the error message with plugin_error().

If no matching filename is found, null is returned. plugin_error() is set to an appropriate error message.

void * DD::Image::plugin_load	(	const char *	name,
		void ()(const char *)	test,
		const char *	arg,
		const char *	symbol = `0`
	)

Load a plugin and make sure it defines some object (such as a script command). The function test(arg) should search for the desired object. arg is typically the name of the object.

This calls test(arg) first and if it returns non-zero that is returned.

It then tries plugin_load(name). If that fails null is returned.

If the plugin does load, test(arg) is called again. If it returns non-zero it returns that value. This will happen if some constructor exectued by loading the plugin added the new object to the correct tables.

If test(arg) fails after loading the plugin, plugin_error() is set to a message with the filename of the plugin saying the plugin did not define symbol. If symbol is null then name is used.

Thus when this returns, either a pointer to the desired object is returned, or null is returned and a useful error message is in plugin_error().

References plugin_load(), plugin_name(), and snprintf().

const char * DD::Image::plugin_load_all ( const char * name )

Load the plugin from every directory in getPluginPath(). This may load several plugins, only the name of the last one is returned. The directories in getPluginPath() are tried in backwards order, so that "earlier" plugins may override later ones.

This is used by Nuke to load the init.py and menu.py plugins.

The name of the last plugin found is returned, or NULL if no plugin was found.

The last error produced by any of the plugins is reported by plugin_error(). However if no matching plugin was found this is not considered an error.

void DD::Image::plugin_addpath ( const char * name )

Add a directory to getPluginPath(). Nothing is done if the directory is already in the path (this is done with simple strcmp so an exact match is needed). name is copied to our own storage.

Normally the new directory is added to the start of the path, ie the most recently added directory is searched first.

However if we are currently inside a plugin_load_all/one() call the directory is inserted before the directory we are currently reading from. In addition if the filename does not start with a slash (or letter, colon, slash on NT) then it is appended to the current directory. This allows an init.tcl file to "plugin_addpath ./subdir" and make subdir be searched without knowing the current directory name. If there is an init.tcl in the subdirectory it will be sourced as well.

void * DD::Image::plugin_binary	(	const char *	name,

	)

plugin_load() calls this for a binary plugin. You can call it yourself to load dynamic objects in a portable way.

This returns zero and sets plugin_error() if there is any problem loading the file as a plugin.

If symbol is non-zero, it locates that symbol in the plugin and returns a pointer to it. If the symbol is not found this returns zero and sets plugin_error().

If symbol is zero, this just returns a non-zero value if the plugin successfully loads. Stuff in the init portions of the object will be executed, this is how all DDImage plugins initialize themselves.
