Optimization Notice

The Intel® Integrated Performance Primitives (Intel® IPP) library contains functions that are more highly optimized for Intel microprocessors than for other microprocessors. While the functions in the Intel® IPP library offer optimizations for both Intel and Intel-compatible microprocessors, depending on your code and other factors, you will likely get extra performance on Intel microprocessors. While the paragraph above describes the basic optimization approach for the Intel® IPP library as a whole, the library may or may not be optimized to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include Intel® Streaming SIMD Extensions 2 (Intel® SSE2), Intel® Streaming SIMD Extensions 3 (Intel® SSE3), and Supplemental Streaming SIMD Extensions 3 (Intel® 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. Intel recommends that you evaluate other library products to determine which best meets your requirements.

Opening a BMP file and saving as JPEG using the settings: Bas, 444, Huffman, RGB, quality=75 results in a grayscale and distorted JPEG file.

DPD200134360 - ippiDecodeHuffman8x8_Direct_JPEG_1u163_C1 read beyong input data
An issue with the above function when decoding a JPEG file under certain conditions; the function reads beyond the input data. This is reported by Valgrind or when using the Electric Fence tool. This has been tested on Linux both 32-bit and 64-bit. The "unoptimized" variants (i.e. 'px' and 'mx') do not exhibit this problem. Although not tested, the problem may also occur on Windows.

DPD200134372 - read error in 'ippiDCTQuantInv8x8To2x2LS_JPEG_16s8u_C1R' for JPEG decoding
A problem in the above function exists when reducing JPEG images to a lower resolution. The problem occurs when 'ippiDCTQuantInv8x8To2x2LS_JPEG_16s8u_C1R' and an inverse DCT, inverse quantization and level-shifting is focused on the upper-left 2x2 part of an 8x8 block. The function reads "too far" in the *destination* buffer. This can cause a read access violation. Observed on *both* Linux and Windows and both 32-bit and 64-bit optimizations. The "unoptimized" 'px' (32-bit) and 'mx' (64-bit) variants do not exhibit the problem.

DPD200134376 - bug in colors for planar destinations at lower resolution option in 'JPEGView'
Not a bug but a request for a new mode: decoding of reduced resolution for planar output image format. When choosing to decode to smaller resolutions and extract native data in planar YCbCr format, the color planes seem to be wrongly handled as the resulting image shows color errors. Only the left half of image contains color, that is incorrect.

DPD200133366 - resolution not saved in JPEG
The sample code encoder/decoder does not pass Image Resolution (DPI) for JPEG.
