Hi. I did write code to write a simple tga file format file.

Unfortunately, it does not seem to work as expected. The resulting image is always black, not matter the color values I write on the file. Here is the code:

Code:
#include <fstream>

using namespace std;

main () {
   int a = 1024;
   int b = 768;
   int c = 24;
   ofstream ofs ("x.tga", ios::binary);
         ofs.put (0), ofs.put (0), ofs.put (2), ofs.put (0), ofs.put (0), ofs.put (0);
         ofs.put (0), ofs.put (0), ofs.put (0), ofs.put (0), ofs.put (0), ofs.put (0);
         ofs.put (a), ofs.put (a >> 8), ofs.put (b), ofs.put (b >> 8);
         ofs.put (c),   ofs.put (0);   
   for (int i=0; i<a; i++)
      for (int j=0; j<b; j++)
         ofs.put (1),          ofs.put (0),          ofs.put (0);         
   ofs.close ();   
}

Can you please provide which language you are using?

That is C++ code. It doesn't seem to be using anything recent, so any supported C++ dialect can probably parse it.
