Here's mail with > prefix, I was using "Indent original messages on replies and forwards" but it seems that not all can see that indent. I wasn't sure how much to remove from the original post so I mailed the whole messages.

Now my question:

I read the libtiff tutorial which suggests using (tsize_t)-1) as it will read in the whole tile/strip by default. It seems to work okay for me.

I'm now writing out the extrasamples tag but still IMAGINE can't open the file for viewing.

This is how I get/set in the tags is this correct?

 TIFFGetField(tif, TIFFTAG_EXTRASAMPLES, &tags->extra, &tags->extraTypes);
 TIFFSetField(wtif, TIFFTAG_EXTRASAMPLES, wtags.extra, wtags.extraTypes);

Where tag members are:

   uint16 extra;
   uint16 *extraTypes;

Thanks,
