int DD::Image::ValueStuffI::value_stuff | ( | int | what, |
ValueStuffArg * | user = 0 |
||
) | const [virtual] |
Used to pass most of the get/set value functions to the Array_Knob subclass implemented inside Nuke. You may be able to make your knob act like Array Knob by overriding this. The default version returns false.
bool DD::Image::ValueStuffI::set_value | ( | double | v, |
int | channel = -1 |
||
) | [inline] |
bool ValueStuffI::set_value(double value, int index);
Change the value of the knob to this value. If the knob stores multiple channels, index is which one to change, or use -1 to change them all. If the channel is animated this will set a keyframe. Returns true if this value is different than the old one.
Referenced by DD::Image::Write::set_file_type().
bool DD::Image::ValueStuffI::set_value_at | ( | double | v, |
double | time, | ||
int | channel = -1 |
||
) | [inline] |
bool ValueStuffI::set_value_at(double value, double time, int index);
Change the value of the knob at the given time. If the knob is not animated this is the same as set_value(). If you want to make sure the knob is animated call set_animated() first.
bool ShapeKnob::set_key | ( | int | channel = -1 , |
int | view = -1 |
||
) | [inline] |
If at_key() is true this will change it by calling set_key(int) and return false.
If at_key() is false this will call add_key() and return true.
bool DD::Image::ValueStuffI::remove_key | ( | int | channel = -1 | ) | [inline] |
bool ValueStuffI::remove_key(int index) Removes a keyframe, if it exists, at the current frame. Does nothing if the knob is not animated. If the knob stores multiple channels, then index picks which one, or use -1 to do all channels. Returns true if any keyframes were deleted.
bool DD::Image::ValueStuffI::remove_key_at | ( | double | time, |
int | channel = -1 , |
||
int | view = -1 |
||
) | [inline] |
bool ValueStuffI::remove_key_at(double time, int index) Removes all keyframes at time.
void DD::Image::ValueStuffI::set_range | ( | double | a, |
double | b, | ||
bool | force = false |
||
) | [inline] |
void ValueStuffI::set_range(double a, double b, bool force=false); Set the range displayed by the GUI slider to a..b. force turns on the FORCE_RANGE flag.
void DD::Image::ValueStuffI::set_animation | ( | const char * | a, |
int | channel = -1 |
||
) | [inline] |
void ValueStuffI::set_animation(const char *, int index); Turn on the animation and replace the curve and expression with a new one parsed from the string. See Animation::from_script() for the format of the string. If index is -1 it puts the same curve on all channels.
bool DD::Image::ValueStuffI::is_key_at | ( | double | time, |
int | channel = -1 , |
||
int | view = -1 |
||
) | const [inline] |
bool ValueStuffI::is_key_at(double time, int index); Return true if there is a keyframe at time.
bool DD::Image::ValueStuffI::is_key | ( | int | channel = -1 | ) | const [inline] |
bool ValueStuffI::is_key(int index) Returns true if there is a keyframe at the current frame. If there are multiple channels then index picks which to check, or use -1 for all channels.
double DD::Image::ValueStuffI::get_value | ( | int | channel = 0 | ) | const [inline] |
double ValueStuffI::get_value(int index); Return the numeric value. If it is animated the value at the current frame is returned. If the knob stores multiple channels then index indicates which one (defaults to 0).
Referenced by DD::Image::Read::append(), DD::Image::RenderScene::build_handles(), DD::Image::Write::isWrite(), DD::Image::Executable::skipForContext(), and DD::Image::InternalOCIOOp::updateColorManagementSetting().
double DD::Image::ValueStuffI::get_value_at | ( | double | time, |
int | channel = 0 |
||
) | const [inline] |
double ValueStuffI::get_value_at(double time, int index); If it is animated, return the value at the given time. If not animated this is the same as get_value().
bool DD::Image::ValueStuffI::set_expression | ( | const char * | v, |
int | channel, | ||
int | view = -1 |
||
) | [inline] |
void ValueStuffI::set_expression(const char *expr, int index); Turn on the animation if it is not on, and replace the expression with a new one. If index is -1 it puts the same expression in all channels.
double DD::Image::LookupCurves::getNthDerivative | ( | int | n, |
double | time, | ||
int | channel = 0 , |
||
int | view = -1 |
||
) | const [inline] |
Return the n'th derivative of the curve at x. If n is zero this acts like evaluate()
bool DD::Image::ValueStuffI::set_animated | ( | int | channel = -1 | ) | const [inline] |
void ValueStuffI::*set_animated(int index); Turn on the animation. Does nothing and returns false if already animated. If there are multiple channels, index picks which to animate, or use -1 for all of them.
bool DD::Image::ValueStuffI::is_animated | ( | int | channel = -1 | ) | [inline] |
bool ValueStuffI::is_animated(int index); Return true if the knob is animated. Use index to only check a certain channel, or use -1 for all of them.
bool DD::Image::ValueStuffI::clear_animated | ( | int | channel = -1 | ) | [inline] |
void ValueStuffI::clear_animated(int index); Delete the animation, if any. The knob is left at a constant value equal to whatever value the animation had at the current frame. Use index to only delete a channel, or -1 to delete all of them.
