Comment on Passing MTLTexture to Metal Core Image Kernel

Correct. But it also creates a Metal context by default if you just use CIContext(). You would need to have a Metal-based context anyways if you want to use Metal Core Image kernels.

Comment on Create Tone Curve Filter in CoreImage

To sample in the middle of the pixel. For instance, if your sampler would use linear sampling, the coordinate 1.0 would return a mix of the first and the second pixel since it's between those pixels. 1.5 would only return the color value of the second pixel.

Comment on Is OpenEXR supported

Can you please try creating a larger image (16x16, for instance) and try again? I was also observing strange behavior (see above) for small EXR images. It would be interesting if these issues are related.

Comment on PHPicker: handle missing internet connection

Thanks for the reply! You are right, but it will unfortunately still just stay at 0% until the timeout kicks in after 5 minutes. There is no way to detect that it's simply not possible to download the item due to a missing connection or the cellular option being disabled.
