Convert MfArray to UnsafeMutablePointer<Float32>?

[vtn98]

Hi @jjjkkkjjj
I have created an MfArray from UImage, now I want to convert it to UnsafeMutablePointer? in swift. How can I do that? Please help me. Thank you

When you convert UIImage into MfArray, you can access the pointer by withUnsafeMutableStartPointer

Matft/Sources/Matft/core/util/pointer/withptr.swift

Line 20 in d70047a

public func withUnsafeMutableStartPointer<T, R>(datatype: T.Type, _ body: (UnsafeMutablePointer<T>) throws -> R) rethrows -> R{

How about like this?

var image = Matft.image.cgimage2mfarray(self.swapImageView.image!.cgImage!)
image.withUnsafeMutableStartPointer(datatype: Float.Type) {
   ptr in
   // note: ptr is UnsageMutablePointer<Float>
}
