2 Intel ® Integrated Performance Primitives Developer Reference, Volume 2: Image Processing Status Code Message ippStsEpsValErr Negative epsilon value. ippStsScaleRangeErr Scale bounds are out of range. ippStsThresholdErr Invalid threshold bounds. ippStsWtOffsetErr Invalid offset value for the wavelet filter. ippStsAnchorErr Anchor point is outside the mask. ippStsMaskSizeErr Invalid mask size. ippStsShiftErr Shift value is less than zero. ippStsSampleFactorErr Sampling factor is less than, or equal to zero. ippStsResizeFactorErr Resize factor(s) is less than, or equal to zero. ippStsDivByZeroErr An attempt to divide by zero. ippStsInterpolationErr Invalid interpolation mode. ippStsMirrorFlipErr Invalid flip mode. ippStsMoment00ZeroErr Moment value M(0,0) is too small to continue calculations. ippStsThreshNegLevelErr Negative value of the level in the threshold operation. ippStsContextMatchErr Context parameter does not match the operation. ippStsFftFlagErr Invalid value of the FFT flag parameter. ippStsFftOrderErr Invalid value of the FFT order parameter. ippStsMemAllocErr Not enough memory for the operation. ippStsNullPtrErr Pointer is NULL. ippStsSizeErr Wrong value fopr the data size. ippStsBadArgErr Invalid or bad argument. ippStsNoErr No errors. ippStsNoOperation No operation has been executed. ippStsMisalignedBuf Misaligned pointer in operation in which it must be aligned. ippStsSqrtNegArg Negative value(s) of the argument in the function Sqrt. ippStsInvZero INF result. Zero value was met by InvThresh with zero level. ippStsEvenMedianMaskSize Even size of the Median Filter mask was replaced by the odd number. ippStsDivByZero Zero value(s) of the divisor in the function Div . ippStsLnZeroArg Zero value(s) of the argument in the function Ln. ippStsLnNegArg Negative value(s) of the argument in the function Ln. ippStsNanArg Argument value is not a number. ippStsDoubleSize Sizes of image are not multiples of 2. ippStsJPEGMarker JPEG marker in the bitstream. ippStsResFloor All result values are floored. ippStsAffineQuadChanged The fourth ertex of destination quad is not equal to the customer's one. ippStsWrongIntersectROI Incorrect ROI that has no intersection with the source or destination image. No operation. ippStsWrongIntersectQuad Incorrect quadrangle that has no intersection with the source or destination ROI. No operation. ippStsSymKernelExpected The kernel is not symmetric. ippStsEvenMedianWeight Even weight of the Weighted Median Filter was replaced by the odd one. ippStsNoAntialiasing The mode does not support antialiasing. ippStsAlgTypeErr The algorithm type is not supported. ippStsAccurateModeNotSupported Accurate mode is not supported. The status codes ending with Err (except for the ippStsNoErr status) indicate an error; the integer values of these codes are negative. When an error occurs, the function execution is interrupted. The status code ippStsNoErr indicates no error. All other status codes indicate warnings. When a specific case is encountered, the function execution is completed and the corresponding warning status is returned. For example, if the function ippiDiv meets an attempt to divide a positive value by zero, the function 30
Intel ® Integrated Performance Primitives Concepts 2 execution is not aborted. The result of the operation is set to the maximum value that can be represented by the source data type, and the user is warned by the output status ippStsDivByZero. See appendix A Handling of Special Cases for more information. Platform-Aware Functions for Image Processing Intel ® Integrated Performance Primitives (Intel ® IPP) library provides so-called platform-aware functions. These functions use the special data type IppSizeL for object sizes. The IppSizeL data type represents memory-related quantities: it can be 32- or 64-bit wide depending on the target architecture. While the rest of Intel IPP functions support only objects of 32-bit integer size, platform-aware functions can work with 64-bit object sizes if it is supported by the platform. The API of platform-aware functions is similar to the API of other Intel IPP functions and has only slight differences. You can distinguish platform-aware functions by the L suffix in the function name, for example, ippiAdd_8u_C1RSfs_L. Currently, the following image processing functions have platform-aware APIs: Function Group Header Function Name Arithmetic Functions ippi.h/ippi_l.h Add AddC Sub SubC Mul MulC Div Linear Filters ippi.h/ippi_l.h FilterBilateralBorderGetBu fferSize FilterBilateralBorderInit FilterBilateralBorder Resize Transform Functions ippi.h/ippi_l.h ResizeGetSize ResizeGetBufferSize ResizeGetBorderSize Resize{Nearest|Linear| Cubic|Lanczos|Super}Init Resize{Nearest|Linear| Cubic|Lanczos|Super} ResizeAntialiasing{Nearest |Linear|Cubic|Lanczos| Super}Init ResizeAntialiasing{Nearest |Linear|Cubic|Lanczos| Super} Support Functions ippi.h/ippi_l.h Malloc Intel IPP platform-aware functions are documented as additional flavors to the existing functions declared in standard Intel IPP headers (without the l suffix). The ippi_l.h header is included into ippi.h. Threading Layer Functions Intel ® Integrated Performance Primitives (Intel ® IPP) library provides threading layer (TL) functions for image processing. It is a set of functions that are implemented as wrappers over Intel IPP platform-aware functions by using tiling and multithreading with OpenMP*. For implementation details, please see the corresponding source code files. The API of TL functions is similar to the API of other Intel IPP functions and has only slight differences. You can distinguish Intel IPP TL functions by the _LT suffix in the function name, for example, ippiAdd_8u_C1RSfs_LT. 31
