planarBuffers()
Returns four 8-bit planar pixel buffers that contain the deinterleaved channels of the 32-bit buffer.
Declaration
func planarBuffers() -> [vImage.PixelBuffer<vImage.Planar8>]Return Value
An array of planar pixel buffers.
Discussion
This function treats 32-bit floating point pixels represented by the range 0 ... 1 as the Pixel_8 range `0 … 255`.
Use this function to deinterleave a buffer and create four new planar buffers that contain copies of each source channel. For example, the following code generates four 1 x 1 planar buffers from an vImage.InterleavedFx4 pixel buffer:
let src = vImage.PixelBuffer<vImage.InterleavedFx4>(
pixelValues: [0.125, 0.25, 0.5, 1] as [Float],
size: vImage.Size(width: 1, height: 1))
let planarBuffers: [vImage.PixelBuffer<vImage.Planar8>] = src.planarBuffers()
// Prints "[32] [64] [128] [255]"
for planarBuffer in planarBuffers {
print(planarBuffer.array)
}
