Dear TIFF forum members,

Is there any possibility to let the following simple (modified) sample
from http://www.ibm.com/developerworks/linux/library/l-libtiff/ use the
tiffbuffer instead of writing the output.tif to the filesystem?

I'll need this, because I'm trying to write mxf files (single large  
file),
which will contain a sequence of DNG/TIFF images...

Thanks in advance
Johann

int main(int argc, char *argv[]){
  // Define an image
  char buffer[25 * 144] = { /* boring hex omitted */ };

  /* tiff output buffer, somewhat bigger than the original buffer */  
char
tiffbuffer[25*144*2];

  TIFF *image;

  // Open the TIFF file
  if((image = TIFFOpen("output.tif", "w")) == NULL){
    printf("Could not open output.tif for writing\n");
    exit(42);
  }

  // We need to set some values for basic tags before we can add any  
data
TIFFSetField(image, TIFFTAG_IMAGEWIDTH, 25 * 8);
