@warrenm Super Thanks to your site and Book! however I am stuck trying to subclass #MPSUnaryImageKernel in objC do you have any examples?
-
@warrenm with the encodeToCommandBuffer method and how to deal with if the in place operation fails. The guard statement in your sample
@Jmade I would think that would just turn into if (copyAllocator == nil) return NO; unless your kernel can operate in-place w/o allocations.

@warrenm okay, that makes sense. Otherwise you would get the texture from the copyAllocator and send it to the other encode command?Thanks. Twitter will use this to make your timeline better. UndoUndo

@warrenm Thanks for the help. What do would “texture.memory = destTexture” look like in objC? -
@Jmade That would turn into an assignment to the out param, something like *texture = destTexture, I think. -
@warrenm It’s seems that Swift’s Optionals were throwing me for a loop. How can you tell If the in-place operation succeeds or fails? -
@Jmade Depends entirely on what you're doing; every operation has its own set of failure modes.
