Need help with fstream

Hi, having trouble getting this to work with a .raw file...
When the texture is mapped it displays the image all in black.
Can someone please give me a hint as to what im doing wrong?

This is the image reading function:

Code:

//some previous declarations:
//typedef 	GLubyte pixel;
//pixel image[MAXROW][MAXCOL][3];
//int charin;
//int r,c;
//ifstream in;

void InputImage(void)
{
	printf("Enter the name of the input file: ");
	gets(inf_name);

	in.open(inf_name,ios::binary);
    
	if(in.fail())  /* open failed */
        {
         puts("*** Can't open input file - please check file name typed!\n ");
         charin = getchar();
         exit(1);
        }

  	for ( r = 0;  r < MAXROW; r++ )
      	       for ( c = 0;  c < MAXCOL; c++)  {
			if(in.eof()) {
				
			    printf("*** End of file reached!\n ");
			    in.close();    /* close input file  */
			    charin = getchar();
			    exit(1);
			}
			else {
			
			    in >> charin;
			    image[r][c][0] = image[r][c][1] = image[r][c][2] = charin;
			}
                }
	in.close();    /* close input file  */
	printf("\nImage input completed!\n");
 }	/* end InputImage */

Any help would be great, thanks.

You need to read and write using the read and write functions in fstream since you are working with binary data. The operator>> does formatted input and skips over whitespace.
