[Openexr-user] Woen't Compile no matter what.

[Thomas Lock]

Hi Everyone

                 I would like to expose the reading and writing of EXR files
to other languages that i use, but nothing i have tried works as of yet. So
here is my problem. I'm using Visual C++ 2005 EE. As i am still pretty new
to C++ what headers do i need to call, i'm just guessing cause i can't find
a single document that tells me this. All i want to do is be able to read
and write Rgba files for now, and make it a simple as possible.

my code for reading. Writing is simple the reverse function of this.

extern "C" void WINAPI writeOpenEXR (char *filename, int width, int height,
float* Bits128)
{
    using namespace  Imf;
    using namespace  Imath;

    int i=0;
    const char fileName[]=&filename[0];
    int bitcount=width*4*height;
    int LineWidth=width*4;
    Array2D<Rgba> p2 (width, height);
    for(int h=0;h<height;h++)for(int b=0;b<width;b++)
    {
        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]);
        //Still have to fix alpha to be precalculated but don't care about
that at this time since i can't do anything yet.
        p2[b][h].a=half::half(Bits128[i + 3]);
    }

    // ALL CODE FROM THIS POINT ON JUST CAUSES APPS TO CRASH TEST BY REMING
OUT THE LAST THREE LINES
    RgbaOutputFile file ("c:\foo.exr", width, height, WRITE_RGBA); // 1

    //EVEN WHEN THESE LAST FUNCTION ARE REMOVED IT STILL FAILS
    file.setFrameBuffer (&p2[-height][0], 1, width); // 2
    file.writePixels (height); // 3
}
