In the following code, when I attemp to load a 24bit, 320*200 file and place
on the screen it returns after puting only about 750 pixles.  Also I know
this because if I skip the eof() test it will make 90% of the screen white.
(could be lightest gray).  The file that I am loading is one saved by PSP 4
in the RAW format ( 24bit, ordered, not flipped RRGBRGBR...)

Any help would be greatly preciated :-)

#include <fstream.h>

void Raw::Load(char * Name, int dx = 320, int dy = 200, int tx=0, int ty=0)
{
        char r,g,b,rgb;

        ifstream temp(Name);

        if(!temp) exit(3);

        for(int ly = 0; ly < dy; ly++)
        {
          for(int lx = 0; lx < dx; lx++)
          {
                        if(temp.eof()) return;

                        r=temp.get();
                        g=temp.get();
                        b=temp.get();


                        r=(r>>5);
                        g=(g>>5);
                        b=(b>>6);


                        rgb= (r<<5)+(g<<2)+b;

          PutPixel(rgb,lx+tx,ly+ty);
}
 }

 temp.close();
}
