How can one find out how many bytes were written out for a TIFF image? If I use no compression, then it is just width * height * 3 + H, were H is some amount of TIFF header (tag) information. Anyone know what H is?
What if I do use packbits compression; how long is the file then? I guess what would be great is some function I can call after TIFFClose that tells me how many bytes were written out. When I looked at the code for PackBitsEncodeI do not see any magical global keeping track of how many bytes are being written out with each encoded strip. So I do not see an easy modification to get at this information. Anyone ever look into this? Anyone else need this?
(file size after writing TIFF) - (file size before adding TIFF)
If the file is closed and re-opened, you could use O/S calls to retrieve the file size (i.e., _stat); if the file is open, you can use _seek on the fd.
