Declared In: |
Defines the functions the application provides to retrieve parameter values.
getGradientSamples:numSamples:depth:fromParm:atTime: |
Gets the Gradient parameter settings.
- (BOOL)getGradientSamples:(void *)samples numSamples:(UInt32)numSamples depth:(UInt32)sampleDepth fromParm:(UInt32)parmId atTime:(double)time;

parmId
time
Returns YES if the value is successfully retrieved; NO otherwise.
Depending on the host application, the time value may be relative to the start of the timeline or to the start of the clip. See the header file FxPlug/FxHostCapabilities.h.
