<p>Image compression primitives. </p>
<p>The JPEG standard defines a flow of level shift, DCT and quantization for forward JPEG transform and inverse level shift, IDCT and de-quantization for inverse JPEG transform. This group has the functions for both forward and inverse functions.</p>
<p>These functions can be found in the nppicom library. Linking to only the sub-libraries that you use can significantly save link time, application load time, and CUDA runtime startup time when using dynamic libraries. </p>

<p>This function can be used in two ways, depending on how much control do you need:</p>
<ol type="1">
<li>Decode whole scan in one job. That is accomplished when the job.eKind is set to <a class="el" href="group__image__compression.html#gga186a8c2fbc29d26049b8ab79c4b79c83a7a37e7ce40d4e8089c70c2bbee871949">NPPI_JPEG_DECODE_SIMPLE</a>. Nppi function handless all in-scan synchronization (if needed). This is described in example.</li>
<li>Split decoding of scan into multiple jobs. In this case, caller is responsible necessary synchronizations. If multiple jobs from the same scan claim to use the same additional buffer, it means that the jobs are exchaning information throught this buffer and the buffer should not be reused or reallocated meanwhile, additionaly if the buffer is used first by PRE job, and then by CPU job, caller has to call cudaStreamSynchronize before CPU job. <a class="el" href="group__image__compression.html#ga186a8c2fbc29d26049b8ab79c4b79c83">NppiJpegDecodeJobKind</a> for more information.</li>
