Class CMTimeRoundingMethod

  • public final class CMTimeRoundingMethod
extends java.lang.Object
    [@enum] CMTimeRoundingMethod Rounding method to use when computing time.value during timescale conversions. [@constant] kCMTimeRoundingMethod_RoundHalfAwayFromZero Round towards zero if abs(fraction) is < 0.5, away from 0 if abs(fraction) is >= 0.5. [@constant] kCMTimeRoundingMethod_Default Synonym for kCMTimeRoundingMethod_RoundHalfAwayFromZero. [@constant] kCMTimeRoundingMethod_RoundTowardZero Round towards zero if fraction is != 0. [@constant] kCMTimeRoundingMethod_RoundAwayFromZero Round away from zero if abs(fraction) is > 0. [@constant] kCMTimeRoundingMethod_QuickTime Use kCMTimeRoundingMethod_RoundTowardZero if converting from larger to smaller scale (ie. from more precision to less precision), but use kCMTimeRoundingMethod_RoundAwayFromZero if converting from smaller to larger scale (ie. from less precision to more precision). Also, never round a negative number down to 0; always return the smallest magnitude negative CMTime in this case (-1/newTimescale). [@constant] kCMTimeRoundingMethod_RoundTowardPositiveInfinity Round towards +inf if fraction is != 0. [@constant] kCMTimeRoundingMethod_RoundTowardNegativeInfinity Round towards -inf if fraction is != 0.
