RGB Image Formats

In addition to the 24-bit-per-pixel RGB/BGR image formats, the Intel IPP color conversion functions support 32-bit-per-pixel RGB/BGR formats, which include three RGB channels plus alpha channel. For 24-bit formats, each color is one byte, every pixel is three bytes. For 32-bit formats, each color is one byte and alpha component is one byte, which yields four bytes per pixel. Memory layout for these formats is given in Table
“Pixel-Order Image Formats”
.
For 16-bit formats, every pixel is two bytes and each color occupies a specified number of bits.
The figure below
shows all the supported 16-bit-per-pixel formats and their memory layout (bit order):

Product and Performance Information

1

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
