Detailed Description

MungeSamplesInfo structure width number of pixels numChannels number of channels to skip extraChannels number of channels to strip alphaIndex if >= 0 and alphaType is kPMAlphaAssociated, zero-based index of extra channel to use as the alpha. If alphaType is kPMAlphaUnassociated, zero-based index of extra channel to keep. colorSpace kPMGrayColorSpace, kPMRGBColorSpace, kPMCMYKColorSpace, kPMICCLabColorSpace alphaType type of data in the extra channels - either kPMAlphaAssociated or kPMAlphaUnassociated. kPMAlphaAssociated will leave the color channels unchanged. kPMAlphaUnassociated will multiply the color channels by the white alpha
