how to convert jpeg byte array to bitmap byte array using visual studio C++

Question

I've processed a jpeg byte array from a camera. Now I need to convert this jpeg byte array to bitmap byte array using visual studio C++

Answer 1

You'll need a library for that. Eg jpeg-compressor . Using jpeg-compressor, "conversion" to bitmap is straightforward:

#include "jpeg-compressor/jpgd.h"

int width = 0, height = 0, actual_comps = 0;
jpgd::decompress_jpeg_image_from_memory(
    static_cast<unsigned char*>(myJPEGdata), myJPEGdataLength,
    &width, &height, &actual_comps, 3 );
