https://community.intel.com/t5/Intel-Integrated-Performance/questions-about-jpeg-lossless-compression/m-p/989492#M22113 Hello, You may look at some high level sample code: In the jpeg.cpp file, the function IM_ERROR SaveImageJPEG(..) shows how to encode the image into the lossless jpeg. The function support one mode on lossless JPEG encoding.

I'm not so good at C/C++. After I looked into the UIC sample source code and the IPP documents, I still could not figure out how to use function&nbsp;ippiEncodeHuffmanRow_JPEG_16s1u_P4C1. If I'm not wrong, I need to call this function for each row of the input image? And how to use the last input parameter&nbsp;bFlushState? Currently I set it to 1 after all the rows has been huff encoded. Could anyone give me some advice? Thanks in advance.</P> <P></P> <P>Guanshuo</P> Tue, 04 Sep 2012 15:12:51 GMT https://community.intel.com/t5/Intel-Integrated-Performance/questions-about-jpeg-lossless-compression/m-p/989491#M22112 Guanshuo_X_ 2012-09-04T15:12:51Z https://community.intel.com/t5/Intel-Integrated-Performance/questions-about-jpeg-lossless-compression/m-p/989492#M22113 Hello, You may look at some high level sample code: In the jpeg.cpp file, the function IM_ERROR SaveImageJPEG(..) shows how to encode the image into the lossless jpeg.
