Detailed Description

   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 fmorphautogen1() and fmorphautogen2() on this SELA.
       These use the text files morphtemplate1.txt and
       morphtemplate2.txt 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 prototypes, and recompile
       the library.  Look at the Makefile to see how I've
       included morphgen.1.c and fmorphgenlow.1.c.  These files
       provide the high-level interfaces for erosion, dilation,
       opening and closing, and the low-level interfaces 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);

     or

PIX   *pixFMorphopGen_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.
       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.

Function Documentation

◆ fmorphautogen()

l_ok fmorphautogen	(	SELA *	sela,
		l_int32	fileindex,
		const char *	filename
	)

fmorphautogen()

Parameters

[in]	sela
[in]	fileindex
[in]	filename	[optional]; can be null

Returns: 0 if OK; 1 on error

Notes:
     (1) This function generates all the code for implementing
         dwa morphological operations using all the sels in the sela.
     (2) See fmorphautogen1() and fmorphautogen2() for details.

Definition at line 243 of file fmorphauto.c.

References fmorphautogen1().

◆ fmorphautogen1()

l_ok fmorphautogen1	(	SELA *	sela,
		l_int32	fileindex,
		const char *	filename
	)

fmorphautogen1()

Parameters

[in]	sela
[in]	fileindex
[in]	filename	[optional]; can be null

Returns: 0 if OK; 1 on error

Notes:
     (1) This function uses morphtemplate1.txt to create a
         top-level file that contains two functions.  These
         functions will carry out dilation, erosion,
         opening or closing 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 fmorphgen.[n].c,
         where [n] is equal to the fileindex parameter.
     (4) If filename != NULL, the output file is [filename].[n].c.
