dlib load jpeg files

Question

I am trying to implement a program using dlib library. I have already been able to use dlib's all other files except the ones related to jpeg and png.

#include "dlib\image_io.h"


#define DLIB_JPEG_SUPPORT


int main(){

    dlib::array2d<dlib::rgb_pixel> arr1;

    dlib::load_jpeg(arr1,"sailboat1234.jpeg");

}

I have included to my project the source.cpp file and the ones inside the dlib/external. Also i have included into c++ general the dlib-18.11 folder which contains the dlib folder. Lastly, the project is running on Visual studio 2012.

EDIT:

When I run the program the error: error C2027: use of undefined type 'dlib::compile_time_assert<value>' . Any ideas?

You forgot to ask a question. – Mark Ransom Jan 06 '15 at 16:57 — Mark Ransom, Jan 06 '15 at 16:57

You need to put the define before the headers for it to have any effect:

#define DLIB_JPEG_SUPPORT
#include "dlib\image_io.h"

For reference see this header:

image_loader\jpeg_loader.h
