i am using libtiff latest version and got image which have EXIF IFD, but i dont thing that libtiff handles EXIF IFD.
i got one function TIFFReadCustomDirectory(TIFF* tif, toff_t diroff, constTIFFFieldInfo info, size_t n) for custom directory..I modified it and some
how it's working. but there no one funtion for writing custom directory like EXIF.
Could anyone suggest me what i have to do?
How do i parse EXIF IFD by using libtiff??
Some functionality got added to LibTiff not too long ago, that could help you do that. Unfortunately, it is not yet documented. If I remember correctly, Andrey did one or two posts about it in this mailing list, and I think one had an example code snippet attached to it.
But I can't seem to find it.
See if you have more luck and/or more persistence. The archive search page is http://www.awaresystems.be/imaging/tiff/tml.html. Obvious search termes that come to mind are 'andrey' 'exif' 'ifd' '"private ifd"'... Remember this is Google, so putting those double quotes around a search term like 'private ifd' means you instruct Google to find exact occurences of that that two-word term.
If you do find it, post the URL in this mailing list as a follow-up to this answer. Google takes the number of pointers to a message into account when attributing value to it, so from that point on the message should be easier to find.
