vImageBuffer_GetSize(_:)
Returns the size, in pixels, of a vImage buffer.
Declaration
func vImageBuffer_GetSize(_ buf: UnsafePointer<vImage_Buffer>) -> CGSizeParameters
- buf:
The vImage buffer to query.
Return Value
The size of the buffer.
Discussion
The vImage library defines a buffer’s width and height as vImagePixelCount values that may be larger than greatestFiniteMagnitude. This function rounds down the buffer’s dimensions to the nearest representable CGFloat values that are less than, or equal to, the size of the buffer.
