| /* |
| * fhmtauto.c |
| * |
| * Main function calls: |
| * l_int32 fhmtautogen() |
| * l_int32 fhmtautogen1() |
| * l_int32 fhmtautogen2() |
| * |
| * Static helpers: |
| * static SARRAY *sarrayMakeWplsCode() |
| * static SARRAY *sarrayMakeInnerLoopDWACode() |
| * 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, char *selname); |
| * |
| * or |
| * |
| * PIX *pixFHMTGen_1(PIX *pixd, PIX *pixs, 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. |
