Hello Drew

                  Before i start using the latest build, i wanted to tryout
the compiled C version you gave me a link to little bit ago. I mostly did
this since i can get it to compile very quickly, but everytime i try to
excute this code from my other app the whole thing crashes. I'm not exacty
sure why but i believe everything upto "RgbaOutputFile" works, so
statementing out the last 3 calls and the app doesn't crash, but of course
doesn't output the exr. Oh ya compiling my AppEXR dll compiles pretty well.
I also added compiled warning messages at the bottom.

#include "stdafx.h"
#include "AppEXR.h"
#include <string.h>
#include <io.h>
#include <ImfRgbaFile.h>
#include <ImfArray.h>

using namespace  Imf;

BOOL APIENTRY DllMain(HANDLE hModule, DWORD  ul_reason_for_call, LPVOID
lpReserved)
{
    return TRUE;
}

extern "C" void WINAPI writeOpenEXR (char *filename, int width, int height,
float* Bits128)
{
 int LineWidth=width*4;
 Header header (width, height);
const char fileName[] = "c:\foo2.exr";
 Array2D<Rgba> p2 (width, height);
 for(int h=0;h<height;h++)for(int b=0;b<width;b++)
 {
  int i=h*LineWidth+(b<<2);
  p2[b][h].b=half::half(Bits128[i]);
  p2[b][h].g=half::half(Bits128[i + 1]);
  p2[b][h].r=half::half(Bits128[i + 2]);
  p2[b][h].a=half::half(Bits128[i + 3]);
 }

 RgbaOutputFile  file (fileName, header, WRITE_RGBA); // 1
 file.setFrameBuffer (&p2[-height][0], 1, width); // 2
 file.writePixels (height); // 3
}
