*
* Main function calls:
* l_int32 fmorphautogen()
* l_int32 fmorphautogen1()
* l_int32 fmorphautogen2()
*
* Static helpers:
* static SARRAY *sarrayMakeWplsCode()
* static SARRAY *sarrayMakeInnerLoopDWACode()
* static char *makeBarrelshiftString()
*
*
* This automatically generates dwa code for erosion and dilation.
* Here's a road map for how it all works.
*
* (1) You generate an array (a SELA) of structuring elements (SELs).
* This can be done in several ways, including
* (a) calling the function selaAddBasic() 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 fmorphautogen() on this SELA. This in turn calls
* fmorphautogen1() and fmorphautogen2(), which use the text
* files morphtemplate1.txt and morphtemplate2.txt, respectively,
* for building up the source code. See the file
* prog/fmorphautogen.c for an example of how this is done.
* The output is written to files named fmorphgen.*.c
* and fmorphgenlow.*.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 fmorphautogen() 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 files back to your src
* directory for compilation. Put their names in the
* Makefile, regenerate the allheaders.h prototype file,
* and recompile the library. Look at the Makefile to see how
* morphgen.1.c and fmorphgenlow.1.c are included. These files
* provide the single high-level interface for erosion, dilation,
* opening and closing, and the lower-level functions to
* do the actual work, for all 58 SELs in the SEL array.
*
* (4) In an application, you now use this interface. Again
* for the example files in the library, using integer "1":
*
* PIX *pixMorphDwa_1(PIX *pixd, PIX, *pixs,
* l_int32 operation, char *selname);
*
* where the operation is one of {L_MORPH_DILATE, L_MORPH_ERODE.
* L_MORPH_OPEN, L_MORPH_CLOSE}, and 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 fmorphgen.1.c.
*
* N.B. Although pixFMorphopGen_1() is global, you must NOT
* use it, because it assumes that 32 or 64 border pixels
* have been added to each side, and it will crash without those
* added pixels.
*
* For examples of use, see the file prog/binmorph_reg1.c, which
* verifies the consistency of the various implementations by
* comparing the dwa result with that of full-image rasterops.
