Primitives

If a function operates on source and destination images that have different data types, the respective data
type identifiers are listed in the function name in order of source and destination as follows:
= [src2Datatype][dstDatatype]
Intel ® Integrated Performance Primitives Concepts 2
For example, the function that converts 8-bit unsigned source image data to 32-bit floating point destination
image data has the 8u32f value for the datatype field.
NOTE
In the lists of function parameters (arguments), the Ipp prefix is written in the data type. For
example, the 8-bit unsigned data is denoted as Ipp8u type. These Intel IPP-specific data types are
defined in the respective library header files.
Descriptors
The descriptors field further describes the operation. Descriptors are individual characters that indicate
additional details of the operation.
The following descriptors are used in image and video processing functions:
Descriptor Description Example
A
A0
C1, C2, C3, C4
C
I
M
P2, P3, P4
R
Sfs
s
Image data contains an alpha channel as the last
channel, requires C4, alpha-channel is not processed
Image data contains an alpha channel as the first
channel, requires C4, alpha-channel is not processed
Image data is in pixel order and made up of 1, 2, 3 or
4 discrete interleaved channels
Channel of interest (COI) is used in the operation
Operation is performed in-place - that is result of
operation is written back into the source (default is notin-place)
Operation uses a mask to determine pixels to be
processed
Image data is in planar order and made up of 2, 3 or 4
discrete planar (non-interleaved) channels, with a
separate pointer to each plane
Function operates on a defined region of interest (ROI)
for each source image
Saturation and fixed scaling mode is used
Saturation and no scaling (default)

If more that one descriptor is used, they are presented in the function name in alphabetical order.
Every function that operates on image data has a channel count descriptor Cn (for interleaved image) or Pn
(for planar). No default channel count is defined.
If input and output channel layouts are different, both source and destination layouts are listed. For example,
the function ippiHLSToBGR_8u_C3P3R converts three-channel interleaved HLS image to the three-plane BGR
image.
