destinationAlpha
Premultiplication description for the destination texture.
Declaration
var destinationAlpha: MPSAlphaType { get }Discussion
Color space conversion operations produce non-premultiplied data. Use this property to tag cases where premultiplied results are required. If the MPSAlphaType.alphaIsOne value is used, the alpha channel will be set to 1. The default value is MPSAlphaType.alphaIsOne.
