-/*
- * Usage:
- ansi2knr [--filename FILENAME] [INPUT_FILE [OUTPUT_FILE]]
- * --filename provides the file name for the #line directive in the output,
- * overriding input_file (if present).
- * If no input_file is supplied, input is read from stdin.
- * If no output_file is supplied, output goes to stdout.
- * There are no error messages.
- *
- * ansi2knr recognizes function definitions by seeing a non-keyword
- * identifier at the left margin, followed by a left parenthesis, with a
- * right parenthesis as the last character on the line, and with a left
- * brace as the first token on the following line (ignoring possible
- * intervening comments and/or preprocessor directives), except that a line
- * consisting of only
- * identifier1(identifier2)
- * will not be considered a function definition unless identifier2 is
- * the word "void", and a line consisting of
- * identifier1(identifier2, <<arbitrary>>)
- * will not be considered a function definition.
- * ansi2knr will recognize a multi-line header provided that no intervening
- * line ends with a left or right brace or a semicolon. These algorithms
- * ignore whitespace, comments, and preprocessor directives, except that
- * the function name must be the first thing on the line. The following
- * constructs will confuse it:
- * - Any other construct that starts at the left margin and
- * follows the above syntax (such as a macro or function call).
- * - Some macros that tinker with the syntax of function headers.

- * The original and principal author of ansi2knr is L. Peter Deutsch
- * <ghost@aladdin.com>. Other authors are noted in the change history
- * that follows (in reverse chronological order):
-
- lpd 2000-04-12 backs out Eggert's changes because of bugs:
- - concatlits didn't declare the type of its bufend argument;
- - concatlits didn't recognize when it was inside a comment;
- - scanstring could scan backward past the beginning of the string; when
- - the check for \ + newline in scanstring was unnecessary.
-
- 2000-03-05 Paul Eggert <eggert@twinsun.com>
-
- Add support for concatenated string literals.
- * ansi2knr.c (concatlits): New decl.
- (main): Invoke concatlits to concatenate string literals.
- (scanstring): Handle backslash-newline correctly. Work with
- character constants. Fix bug when scanning backwards through
- backslash-quote. Check for unterminated strings.
- (convert1): Parse character constants, too.
- (appendline, concatlits): New functions.
- * ansi2knr.1: Document this.
-
- lpd 1999-08-17 added code to allow preprocessor directives
- wherever comments are allowed
- lpd 1999-04-12 added minor fixes from Pavel Roskin
- <pavel_roskin@geocities.com> for clean compilation with
- gcc -W -Wall
- lpd 1999-03-22 added hack to recognize lines consisting of
- identifier1(identifier2, xxx) as *not* being procedures
- lpd 1999-02-03 made indentation of preprocessor commands consistent
- lpd 1999-01-28 fixed two bugs: a '/' in an argument list caused an
- endless loop; quoted strings within an argument list
- confused the parser
- lpd 1999-01-24 added a check for write errors on the output,
- suggested by Jim Meyering <meyering@ascend.com>
- lpd 1998-11-09 added further hack to recognize identifier(void)
- as being a procedure
- lpd 1998-10-23 added hack to recognize lines consisting of
- identifier1(identifier2) as *not* being procedures
- lpd 1997-12-08 made input_file optional; only closes input and/or
- output file if not stdin or stdout respectively; prints
- usage message on stderr rather than stdout; adds
- --filename switch (changes suggested by
- <ceder@lysator.liu.se>)
- lpd 1996-01-21 added code to cope with not HAVE_CONFIG_H and with
- compilers that don't understand void, as suggested by
- Tom Lane
- lpd 1996-01-15 changed to require that the first non-comment token
- on the line following a function header be a left brace,
- to reduce sensitivity to macros, as suggested by Tom Lane
- <tgl@sss.pgh.pa.us>
- lpd 1995-06-22 removed #ifndefs whose sole purpose was to define
- undefined preprocessor symbols as 0; changed all #ifdefs
- for configuration symbols to #ifs
- lpd 1995-04-05 changed copyright notice to make it clear that
- including ansi2knr in a program does not bring the entire
- program under the GPL
- lpd 1994-12-18 added conditionals for systems where ctype macros
- don't handle 8-bit characters properly, suggested by
- Francois Pinard <pinard@iro.umontreal.ca>;
- removed --varargs switch (this is now the default)
- lpd 1994-10-10 removed CONFIG_BROKETS conditional
- lpd 1994-07-16 added some conditionals to help GNU `configure',
- suggested by Francois Pinard <pinard@iro.umontreal.ca>;
- properly erase prototype args in function parameters,
- contributed by Jim Avera <jima@netcom.com>;
- correct error in writeblanks (it shouldn't erase EOLs)
- lpd 1989-xx-xx original version

+Use merged upsample with scaled DCT sizes larger than 8.
+Thank to Taylor Hatala for inspiration.
+
+Check for excessive comment lengths in argument parsing in wrjpgcom.c.
+Thank to Julian Cohen for hint.
+
+Add makefile.b32 for use with Borland C++ 32-bit (bcc32).
+Thank to Joe Slater for contribution.
+
+Document 'f' specifier for jpegtran -crop specification.
+Thank to Michele Martone for suggestion.

* For most steps we can mathematically guarantee that the initial value
- * of x is within MAXJSAMPLE+1 of the legal range, so a table running from
- * -(MAXJSAMPLE+1) to 2*MAXJSAMPLE+1 is sufficient. But for the initial
- * limiting step (just after the IDCT), a wildly out-of-range value is
- * possible if the input data is corrupt. To avoid any chance of indexing
+ * of x is within 2*(MAXJSAMPLE+1) of the legal range, so a table running
+ * from -2*(MAXJSAMPLE+1) to 3*MAXJSAMPLE+2 is sufficient. But for the
+ * initial limiting step (just after the IDCT), a wildly out-of-range value
+ * is possible if the input data is corrupt. To avoid any chance of indexing
* off the end of memory and getting a bad-pointer trap, we perform the
* post-IDCT limiting thus:
- * x = range_limit[x & MASK];
+ * x = (sample_range_limit - SUBSET)[(x + CENTER) & MASK];
* where MASK is 2 bits wider than legal sample data, ie 10 bits for 8-bit
* samples. Under normal circumstances this is more than enough range and
* a correct output will be generated; with bogus input data the mask will
* cause wraparound, and we will safely generate a bogus-but-in-range output.
* For the post-IDCT step, we want to convert the data from signed to unsigned
* representation by adding CENTERJSAMPLE at the same time that we limit it.
- * So the post-IDCT limiting table ends up looking like this:
- * CENTERJSAMPLE,CENTERJSAMPLE+1,...,MAXJSAMPLE,
- * MAXJSAMPLE (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
- * 0 (repeat 2*(MAXJSAMPLE+1)-CENTERJSAMPLE times),
- * 0,1,...,CENTERJSAMPLE-1
- * Negative inputs select values from the upper half of the table after
- * masking.
- *
- * We can save some space by overlapping the start of the post-IDCT table
- * with the simpler range limiting table. The post-IDCT table begins at
- * sample_range_limit + CENTERJSAMPLE.
+ * This is accomplished with SUBSET = CENTER - CENTERJSAMPLE.
*
* Note that the table is allocated in near data space on PCs; it's small
* enough and used often enough to justify this.
