//  * This file documents the configuration options that are required to
//  * customize the JPEG software for a particular system.
//  *
//  * The actual configuration options for a particular installation are stored
//  * in jconfig.h.  On many machines, jconfig.h can be generated automatically
//  * or copied from one of the "canned" jconfig files that we supply.  But if
//  * you need to generate a jconfig.h file by hand, this file tells you how.
//  *
//  * DO NOT EDIT THIS FILE --- IT WON'T ACCOMPLISH ANYTHING.
//  * EDIT A COPY NAMED JCONFIG.H.


//  * These symbols indicate the properties of your machine or compiler.
//  * #define the symbol if yes, #undef it if no.

//  Does your compiler support function prototypes?
//  * (If not, you also need to use ansi2knr, see install.doc)
#define HAVE_PROTOTYPES

//  Does your compiler support the declaration "unsigned char" ?
//  * How about "unsigned short" ?
#define HAVE_UNSIGNED_CHAR
#define HAVE_UNSIGNED_SHORT

//  Define "void" as "char" if your compiler doesn't know about type void.
//  * NOTE: be sure to define void such that "void *" represents the most general
//  * pointer type, e.g., that returned by malloc().
// #define void char 

//  Define "const" as empty if your compiler doesn't know the "const" keyword.
// #define const 

//  Define this if an ordinary "char" type is unsigned.
//  * If you're not sure, leaving it undefined will work at some cost in speed.
//  * If you defined HAVE_UNSIGNED_CHAR then the speed difference is minimal.
#define CHAR_IS_UNSIGNED

//  Define this if your system has an ANSI-conforming <stddef.h> file.
#define HAVE_STDDEF_H

//  Define this if your system has an ANSI-conforming <stdlib.h> file.
#define HAVE_STDLIB_H

//  Define this if your system does not have an ANSI/SysV <string.h>,
//  * but does have a BSD-style <strings.h>.
#undef NEED_BSD_STRINGS

//  Define this if your system does not provide typedef size_t in any of the
//  * ANSI-standard places (stddef.h, stdlib.h, or stdio.h), but places it in
//  * <sys/types.h> instead.
#undef NEED_SYS_TYPES_H

//  For 80x86 machines, you need to define NEED_FAR_POINTERS,
//  * unless you are using a large-data memory model or 80386 flat-memory mode.
//  * On less brain-damaged CPUs this symbol must not be defined.
//  * (Defining this symbol causes large data structures to be referenced through
//  * "far" pointers and to be allocated with a special version of malloc.)
#undef NEED_FAR_POINTERS

//  Define this if your linker needs global names to be unique in less
//  * than the first 15 characters.
#undef NEED_SHORT_EXTERNAL_NAMES

//  Although a real ANSI C compiler can deal perfectly well with pointers to
//  * unspecified structures (see "incomplete types" in the spec), a few pre-ANSI
//  * and pseudo-ANSI compilers get confused.  To keep one of these bozos happy,
//  * define INCOMPLETE_TYPES_BROKEN.  This is not recommended unless you
//  * actually get "missing structure definition" warnings or errors while
//  * compiling the JPEG code.
#undef INCOMPLETE_TYPES_BROKEN


//  * The following options affect code selection within the JPEG library,
//  * but they don't need to be visible to applications using the library.
//  * To minimize application namespace pollution, the symbols won't be
//  * defined unless JPEG_INTERNALS has been defined.

#ifdef JPEG_INTERNALS

//  Define this if your compiler implements ">>" on signed values as a logical
//  * (unsigned) shift; leave it undefined if ">>" is a signed (arithmetic) shift,
//  * which is the normal and rational definition.
#undef RIGHT_SHIFT_IS_UNSIGNED


#endif // JPEG_INTERNALS 


//  * The remaining options do not affect the JPEG library proper,
//  * but only the sample applications cjpeg/djpeg (see cjpeg.c, djpeg.c).
//  * Other applications can ignore these.

#ifdef JPEG_CJPEG_DJPEG

// These defines indicate which image (non-JPEG) file formats are allowed. 

#define BMP_SUPPORTED		// BMP image file format 
#define GIF_SUPPORTED		// GIF image file format 
#define PPM_SUPPORTED		// PBMPLUS PPM/PGM image file format 
#undef RLE_SUPPORTED		// Utah RLE image file format 
#define TARGA_SUPPORTED		// Targa image file format 

//  Define this if you want to name both input and output files on the command
//  * line, rather than using stdout and optionally stdin.  You MUST do this if
//  * your system can't cope with binary I/O to stdin/stdout.  See comments at
//  * head of cjpeg.c or djpeg.c.
#undef TWO_FILE_COMMANDLINE

//  Define this if your system needs explicit cleanup of temporary files.
//  * This is crucial under MS-DOS, where the temporary "files" may be areas
//  * of extended memory; on most other systems it's not as important.
#undef NEED_SIGNAL_CATCHER

//  By default, we open image files with fopen(...,"rb") or fopen(...,"wb").
//  * This is necessary on systems that distinguish text files from binary files,
//  * and is harmless on most systems that don't.  If you have one of the rare
//  * systems that complains about the "b" spec, define this symbol.
#undef DONT_USE_B_MODE

//  Define this if you want percent-done progress reports from cjpeg/djpeg.
#undef PROGRESS_REPORT
