-Subject: Potential TIFF library additions
-
-Delivery-Date: Fri, 01 Aug 1997 19:21:06 -0700
-
-Sam,
-
-You probably don't remember me, but I sent in a couple of bug fixes
-regarding the TIFF library about a 16 months ago or so...
-
-I just wanted to send you two other additions that I have made to our
-local version of the TIFF library in hopes that you will want to
-incorporate them into your next major release of the TIFF library.
-(These additions are based on TIFF version 3.4beta31, but they sit on
-top of the library so they shouldn't be much trouble to incorporate them
-into any more recent version.) They are internally documented to a
-reasonable extent and we've been successfully using them in our code
-here for over a year. If you think they would make good additions to the
-TIFF library, I'd be happy to clean them up more, document them more,
-and/or integrate them with the latest version of the TIFF library, but I
-figured I'd see if you were interested in using them before I went to
-all that trouble.
-
-TIFF Image Iterator
--------------------
-Your ReadRGBA() routine works well for reading many different formats
-(TILED, STIP, compressed or not, etc.) of the most basic types of data
-(RGB, 8-bit greyscale, 8-bit colormapped) into an SGI-style data array,
-and serves as a good template for users with other needs. I used it as
-an exmaple of how to make an iterator which, rather than fill a data
-array, calls an arbitrary user-supplied callback function for each
-"chunk" of data - that "chunk" might be a strip or a tile, and might
-have one sample-per-pixel or two, and might be 8-bit data or 16-bit or
-24-bit. The callback function can do whatever it wants with the data -
-store it in a big array, convert it to RGBA, or draw it directly to the
-screen. I was able to use this iterator to read 16-bit greyscale and 32-
-and 64-bit floating point data, which wasn't possible with ReadRGBA().
-
-I have tested this routine with 8- and 16-bit greyscale data as well as
-with 32- and 64-bit floating point data. I believe nearly all of our
-data is organized in strips, so actually I'd appreciate it if you had
-some tiled images that I could test it with.
-
-It should certainly be possible and would be cleanest to reimplement
-ReadRGBA() in terms of the image iterator, but I haven't done that.
-
-
-Private Sub-Directory Read/Write
---------------------------------
-TIFF-PL is a Phillips Laboratory extension to the TIFF tags that allows
-us to store satellite imaging-specific information in a TIFF format,
-such as the satellite's trajectory, the imaging time, etc. In order to
-give us the flexibility to modify the tag definitions without getting
-approval from the TIFF committee every time, we were given only three
-TIFF tags - a PL signature, a PL version number, and PL directory
-offset, which lists the position in the file at which to find a private
-sub-directory of tags-value pairs. So I wrote two routines:
-TIFFWritePrivateDataSubDirectory(), which takes a list of tags and a
-"get" function and writes the tag values into the TIFF file, returning
-the offset within the file at which it wrote the directory; and
-TIFFReadPrivateDataSubDirectory(), which takes an offset, a list of
-tags, and a "set" function and reads all the data from the private
-directory. The functions themselves are pretty simple. (The files are
-huge because I had to basically copy all of the tif_dirread.c and
-tif_dirwrite.c files in order to access the various fetching routines
-which were all declared static and therefore inaccessible in the TIFF
-library.)
-
-
-I'm including the four source files (tif_imgiter.h, tif_imgiter.c,
-tif_pdsdirread.c, tif_pdsdirwrite.c) in case you want to take a look at
-them. I can also send you some sample code that uses them if you like.
-If you're interested in having them incorporated into the standard TIFF
-library, I'd be happy to do that integration and clean up and document
-the routines. (For example, I've already realized that instead of
-limiting the SEP callback function to three bands (R,G,B) it should take
-an array to enable the handling of n-banded multi-spectral data...) If
-not, I'll just leave them as they are, since they work fine for us now.
-
-Holler if you have any questions.

- * Written by Conrad J. Poelman, PL/WSAT, Kirtland AFB, NM on 26 Mar 96.
- *
- * This file contains code to allow a calling program to "iterate" over each
- * pixels in an image as it is read from the file. The iterator takes care of
- * reading strips versus (possibly clipped) tiles, decoding the information
- * according to the decoding method, and so on, so that calling program can
- * ignore those details. The calling program does, however, need to be
- * conscious of the type of the pixel data that it is receiving.
- *
- * For reasons of efficiency, the callback function actually gets called for
- * "blocks" of pixels rather than for individual pixels. The format of the
- * callback arguments is given below.
- *
- * This code was taken from TIFFReadRGBAImage() in tif_getimage.c of the original
- * TIFF distribution, and simplified and generalized to provide this general
- * iteration capability. Those routines could certainly be re-implemented in terms
- * of a TIFFImageIter if desired.

- * actual writing of data into the structure is handled by the setFieldFn(),
- * which is passed to TIFFReadPrivateDataSubDirectory() as a parameter. The idea is to
- * enable any application wishing to store private subdirectories to do so
- * easily using this function, without modifying the TIFF library.
- *
- * The astute observer will notice that only two functions are at all different
- * from the original tif_dirread.c file: TIFFReadPrivateDataSubDirectory() and
- * TIFFFetchNormalSubTag(). All the other stuff that makes this file so huge
- * is only necessary because all of those functions are declared static in
- * tif_dirread.c, so we have to totally duplicate them in order to use them.
- *
- * Oh, also note the bug fix in TIFFFetchFloat().

- * March 20-21, 1996.
- *
- * The entire purpose of this file is to provide a single external function,
- * TIFFWritePrivateDataSubDirectory(). This function is intended for use
- * in writing a private subdirectory structure into a TIFF file. The
- * actual reading of data from the structure is handled by the getFieldFn(),
- * which is passed to TIFFWritePrivateDataSubDirectory() as a parameter. The
- * idea is to enable any application wishing to read private subdirectories to
- * do so easily using this function, without modifying the TIFF library.
- *
- * The astute observer will notice that only two functions are at all different
- * from the original tif_dirwrite.c file: TIFFWritePrivateDataSubDirectory()and
- * TIFFWriteNormalSubTag(). All the other stuff that makes this file so huge
- * is only necessary because all of those functions are declared static in
- * tif_dirwrite.c, so we have to totally duplicate them in order to use them.

- * Oh, also please note the bug-fix in the routine TIFFWriteNormalSubTag(),

-/* This function will write an entire directory to the disk, and return the
- offset value indicating where in the file it wrote the beginning of the
- directory structure. This is NOT the same as the offset value before
- calling this function, because some of the fields may have caused various
- data items to be written out BEFORE writing the directory structure.
-
- This code was basically written by ripping of the TIFFWriteDirectory()
- code and generalizing it, using RPS's TIFFWritePliIfd() code for
- inspiration. My original goal was to make this code general enough that
- the original TIFFWriteDirectory() could be rewritten to just call this
- function with the appropriate field and field-accessing arguments.
-
- However, now I realize that there's a lot of code that gets executed for
- the main, standard TIFF directories that does not apply to special
- private subdirectories, so such a reimplementation for the sake of
- eliminating redundant or duplicate code is probably not possible,
- unless we also pass in a Main flag to indiciate which type of handling
- to do, which would be kind of a hack. I've marked those places where I
- changed or ripped out code which would have to be re-inserted to
- generalize this function. If it can be done in a clean and graceful way,
- it would be a great way to generalize the TIFF library. Otherwise, I'll
- just leave this code here where it duplicates but remains on top of and
- hopefully mostly independent of the main TIFF library.
-
- The caller will probably want to free the sub directory structure after
- returning from this call, since otherwise once written out, the user
- is likely to forget about it and leave data lying around.
