static char *makeBarrelshiftString()This automatically generates dwa code for the hit-miss transform. Here's a road map for how it all works.
(1) You generate an array (a SELA) of hit-miss transform SELs.
This can be done in several ways, including
(a) calling the function selaAddHitMiss() for
pre-compiled SELs
(b) generating the SELA in code in line
(c) reading in a SELA from file, using selaRead()
or various other formats.(2) You call fhmtautogen1() and fhmtautogen2() on this SELA. This uses the text files hmttemplate1.txt and hmttemplate2.txt for building up the source code. See the file prog/fhmtautogen.c for an example of how this is done. The output is written to files named fhmtgen.*.c and fhmtgenlow.*.c, where "*" is an integer that you input to this function. That integer labels both the output files, as well as all the functions that are generated. That way, using different integers, you can invoke fhmtautogen() any number of times to get functions that all have different names so that they can be linked into one program.
(3) You copy the generated source code back to your src
directory for compilation. Put their names in the
Makefile, regnerate the prototypes, and recompile
the libraries. Look at the Makefile to see how I've
included fhmtgen.1.c and fhmtgenlow.1.c. These files
provide the high-level interfaces for the hmt, and
the low-level interfaces to do the actual work. (4) In an application, you now use this interface. Again
for the example files generated, using integer "1":PIX *pixHMTDwa_1(PIX *pixd, PIX *pixs, const char *selname);
or
PIX *pixFHMTGen_1(PIX *pixd, PIX *pixs, const char *selname);
where the selname is one of the set that were defined
as the name field of sels. This set is listed at the
beginning of the file fhmtgen.1.c.
As an example, see the file prog/fmtauto_reg.c, which
verifies the correctness of the implementation by
comparing the dwa result with that of full-image
rasterops.

| [in] | sela | |

Notes:
(1) This function generates all the code for implementing
dwa morphological operations using all the sels in the sela.
(2) See fhmtautogen1() and fhmtautogen2() for details.

| const char * | filename | ||
| ) |
| [in] | sela | array |
| [in] | fileindex | |
| [in] | filename | [optional]; can be null |
Notes:
(1) This function uses hmttemplate1.txt to create a
top-level file that contains two functions that carry
out the hit-miss transform for any of the sels in
the input sela.
(2) The fileindex parameter is inserted into the output
filename, as described below.
(3) If filename == NULL, the output file is fhmtgen.[n].c,
where [n] is equal to the 'fileindex' parameter.
(4) If filename != NULL, the output file is [filename].[n].c.
(5) Each sel must have at least one hit. A sel with only misses
generates code that will abort the operation if it is called.

Notes:
(1) This function uses hmttemplate2.txt to create a
low-level file that contains the low-level functions for
implementing the hit-miss transform for every sel
in the input sela.
(2) The fileindex parameter is inserted into the output
filename, as described below.
(3) If filename == NULL, the output file is fhmtgenlow.[n].c,
where [n] is equal to the fileindex parameter.
(4) If filename != NULL, the output file is [filename]low.[n].c.
