Converts a Planar1 image to a Planar8 image.


func vImageConvert_Planar1toPlanar8(_ src: UnsafePointer<vImage_Buffer>, _ dest: UnsafePointer<vImage_Buffer>, _ flags: vImage_Flags) -> vImage_Error



A pointer to the source vImage buffer object. Because the source pixel format is smaller than a byte, there are multiple pixels in each byte of the data buffer. These pixels are interpreted as being in big endian order (that is, the low-indexed pixel is in the high-order bits of the byte).

Sub-byte indexing of scanlines is unsupported, because the data and rowBytes fields of the buffer are specified in whole bytes.

Widths, however, are measured in pixels, so a scanline may end in the middle of a byte. If this occurs, the contents of any unused bits of the final byte are ignored.




The options to use when performing the operation. If you plan to perform your own tiling or use multithreading, pass kvImageDoNotTile.

Return Value



For each pixel in the destination image, the resulting value is the corresponding pixel value from the source image multiplied by 255.
