Hello Frank,
I am reading libtiff manual and it is possible to write different IFD
(directories, I do not know the correct word) in the same tiff file using
*TIFFWriteDirectory *function. Is it possible to use it in gdal library?
Jorge,
While in theory we could extend the GDAL library to write multi-image
TIFF files - at this time we do not have support for doing this.
Best regards,

Hello Frank,
TIFF 6.0 specifications has a sub-section in page 16 which is
called "Multiple Image per TIFF file" and there is only a description of
this issue but anything about its implementation:
"There may be more than one IFD in a TIFF file. Each IFD defines a subfile.
One potential use of subfiles is to describe related images, such as the
pages of a facsimile transmission. A Baseline TIFF reader is not required
to read any IFDs beyond the first one."
Is it possible to implement it?
