# vImageConvert_PlanarFToRGBXFFFF Interleaves three 32-bit planar buffers into a floating-point 32-bit-per-channel, 4-channel interleaved RGBX buffer with the specified constant alpha value. ``` #define vImageConvert_PlanarFToRGBXFFFF(_red, _green, _blue, _alpha, _dest, _flags) ``` ## Parameters `_red` The source vImage buffer that contains the red channel. `_green` The source vImage buffer that contains the green channel. `_blue` The source vImage buffer that contains the blue channel. `_alpha` The constant destination alpha value. `_dest` A pointer to the destination vImage buffer structure. You’re responsible for filling out the [`height`](/documentation/Accelerate/vImage_Buffer/height), [`width`](/documentation/Accelerate/vImage_Buffer/width), and [`rowBytes`](/documentation/Accelerate/vImage_Buffer/rowBytes) fields of this structure, and for allocating a data buffer of the appropriate size. On return, the data buffer this structure points to contains the destination image data. When you no longer need the data buffer, deallocate the memory to prevent memory leaks. `_flags` The options to use when performing the operation. If your code implements its own tiling or its own multithreading, pass [`kvImageDoNotTile`](/documentation/Accelerate/kvImageDoNotTile); otherwise, pass [`kvImageNoFlags`](/documentation/Accelerate/kvImageNoFlags). ## Return Value [`kvImageNoError`](/documentation/Accelerate/kvImageNoError); otherwise, one of the error codes in . ## Discussion This routine cannot be used in place. --- Copyright © 2026 Apple Inc.
