==Application Details==
*Description: libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, AVX2, NEON, AltiVec) to accelerate baseline JPEG compression .
*Version: 1.5.1 (compiled with gcc)
*Module: gcc/1.5.1
*Licence: GNU

==Usage Examples==

===Module===
<pre style="background-color: #000000; color: white; border: 2px solid black; font-family: monospace, sans-serif;">
[username@login01 ~]$ module add libjpeg-turbo/gcc/1.5.1
</pre>

===Compilation===

''Libjpeg-turbo'' is a library for use either with a compiled binary that requires it, or it could be required at compilation time also.

A typical code snippet (C++) requiring is shown below:

<pre style="background-color: #f5f5dc; color: black; font-family: monospace, sans-serif;">

#include <turbojpeg.h>

const int JPEG_QUALITY = 85;
const int COLOR_COMPONENTS = 3;
int _width = 640;
int _height = 720;
long unsigned int _jpegSize = 0;
unsigned char* _compressedImage = NULL;
unsigned char buffer[_width*_height*COLOR_COMPONENTS];

tjhandle _jpegCompressor = tjInitCompress();

tjCompress2(_jpegCompressor, buffer, _width, 0, _height, TJPF_RGB,
&_compressedImage, &_jpegSize, TJSAMP_444, JPEG_QUALITY,
TJFLAG_FASTDCT);

tjDestroy(_jpegCompressor);

//to free the memory allocated by TurboJPEG

tjFree(&_compressedImage);

</pre>

Compilation is carried out below, in this example the '''gcc''' compiler is used. However, the applies similarly to the Intel compiler too.

<pre style="background-color: #000000; color: white; border: 2px solid black; font-family: monospace, sans-serif;">

gcc -o tjIMAGE tjIMAGE.cpp -lm -ljpeg

</pre>

+*Description: libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, AVX2, NEON, AltiVec) to accelerate baseline JPEG compression. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.
