CImg: jpg file unknown format.

[lcym]

Hi,
I wrote a small program using CImg library and g++ compiler and I installed imagemagick v6.5.6.

The code is as follows

#include "CImg.h"
using namespace cimg_library;

int main(){
     CImg <unsigned char> img("train.jpg");
     img.display("Train");

     return 0;
}

The program passes compliation but when I run the program, an error message

"CImg <unsigned char>:: load() "train.jpg", format not recognized" prompts me.

What could be cause? Thanks.

Hi,
I have a similar problem for the format .tiff
The error displayed is the following:

sh: convert: not found
sh: gm: not found
sh: convert: not found
sh: gm: not found
sh: convert: not found
sh: gm: not found
terminate called after throwing an instance of 'cimg_library::CImgIOException'
what(): [instance(0,0,0,0,(nil),non-shared)] CImg<float>::load() : Failed to recognize format of file './Train/8008_024.tiff'.

I'm going crazy searching a solution at this error.

Please help!

I have also faced the same problem, but found a solution, after few tries.

Download CImg.h from the website - http://cimg.sourceforge.net/download.shtml
and place it in the same folder as the cpp file.


if the below errors are still found
------------
sh: 1: convert: not found
sh: 1: gm: not found
sh: 1: convert: not found
sh: 1: gm: not found
sh: 1: convert: not found
sh: 1: gm: not found
--------------
Run the command in ubuntu, or install imagemagick
>sudo apt-get install imagemagick libmagickcore-dev

Hopefully, this should solve the prob
