VideoToolbox.h
This file contains the necessary prototypes for use of all the VideoToolbox
files except Luminance.c, which has its own header file, Luminance.h, and
GDInfo.c and GDTestClut.c, which use GDInfo.h.
Precompilation of this header, producing VideoToolbox????.pre,
will reduce your compilation time tenfold. See VideoToolbox.pch (if you're
using Metrowerks CodeWarrior) or VideoToolbox.c (any other compiler) for
instructions.
My convention is to assign different names to the precompiled header depending
on the compile-time options: use of ppc/68k, 68881, and size of int.
The precompilation depends on the sizeof(double) and sizeof(int)
because most functions use or return such values and the external interface must
allow the appropriate amount of space. THINK C supports a 12-byte "universal"
format double that works well both with the 68881 fpu (which uses the top two
bytes and the bottom 8 bytes) and with SANE (which uses the bottom 10 bytes).
Thus in THINK C it is easy to mix modules compiled with (e.g. your code) and
without (e.g. the ANSI library) the 68881 option. Unfortunately that excellent
feature is unique to THINK C. In MPW and CodeWarrior C you must use 10-byte
doubles when you use SANE (i.e. don't use the 68881 fpu), so when you use these
compilers you'll need separate pre-compiled headers, with and without the 68881
option, if you want to compile for each environment: to use the 68881 fpu, or
run on machines that lack it.
Metrowerks CodeWarrior project names end in ".µ", and indicate which cpu they
support by "68k" or "ppc". THINK C projects support only the 68k and have names
ending in ".π".
My naming convention for pre-compiled headers indicates the size of int, "2i" or
"4i", and, if the 68881 is required, "881". Metrowerks pre-compiled headers
indicate which cpu they support by "68k" or "ppc"; THINK C supports only the
68k. The THINK C pre-compiled header that I use is "VideoToolbox.pre", which
uses 2-byte ints and "universal" 12-byte doubles that work with or without the
68881. (The THINK C ANSI library requires 2-byte ints.) The Metrowerks
CodeWarrior C pre-compiled headers that I use are called,
"VideoToolbox.68k.4i.pre", "VideoToolbox.68k.4i.881.pre", and
"VideoToolbox.ppc.pre".
As of June 14, 1995, the VideoToolbox #includes <assert.h>, or, if MATLAB
is true, defines a MATLAB-compatible version of assert(). If your source file
#includes <assert.h> then it will be included again, undoing the work
done here, including the MATLAB compatibility. For that reason you should NOT
#include <assert.h> in your source files.
MAC_C:
Defining the symbol MAC_C as 0 before this file is compiled will leave only the
stuff that is written in pure Standard C, which will work on any computer.
The Apple Macintosh header files use some extensions to C that are not part of
Standard C, e.g. "pascal", "short double", enums larger than ints, and function
prototypes that specify absolute addresses. These keywords and constructions
cannot be compiled in Standard C. The macro MAC_C is defined as true, below,
only on Macintosh C compilers that incorporate these extensions, and is false
otherwise. The MAC_C symbol is used to prevent inclusion of all the
Macintosh-dependent header files and prototypes when the compiler doesn't
support them. However, lacking any general test for these extensions, a test
must be added, below, for each new compiler. At present we test for Symantec C
THINK C, Apple MPW C, and Metrowerks CodeWarrior C.
MATLAB:
If you want to use the VideoToolbox from within MATLAB then you'll be happy
to know that all the work's been done for you. Get yourself a copy of the
Psychophysics Toolbox:
<http://www.psych.ucsb.edu/~brainard/software/>
The VideoToolbox sources can be linked to create a stand-alone C application, or
a MATLAB external code resource (a "MEX" file), to be invoked by typing the
function name from within MATLAB. In that case we call the THINK C project a
"MATLAB project". A MATLAB project must #define the symbol MATLAB as true for
every C file and must #include the VideoToolbox.h header at the beginning of every
C file. You can simply "#define MATLAB 1"; VideoToolbox.h will redefine the
"MATLAB" symbol to correspond to the version of MATLAB defined by the MATLAB
header files, currently version 3, 4, or 5.
Don't #define MATLAB within your C file; use the Edit:Options:THINK C:Prefix
window instead. E.g. you could type
#define MATLAB 1
into the Prefix window.
You must have the file "mex.h" in order to compile this file when "MATLAB" is true.
"mex.h" is distributed by MathWorks as part of MATLAB.
If you're using THINK C to create your MEX file, and you use QuickDraw, then
you'll need PsychLibSources.h and CheckConfig.c from the Psychophysics Toolbox.

HISTORY: (omitting changes documented in C files)
2/20/93 dhb Added various commonly used headers.
Restructured so that only VideoToolbox.h has to be included,
whether one is creating stand-alone THINK C or code resources
to be called by MATLAB. Everything that cares is properly conditioned
by the symbol MATLAB.
7/9/93 dgp Changed our convention for the MATLAB symbol, defining it as
1 or 0 instead of defining or leaving undefined. The advantage of
this approach is that "MATLAB" can now be used as an argument in an
ordinary if statement, which is much more readable than #if.
8/21/93 dhb Added undefs in #if MATLAB so that memory allocation goes through THINK C
library, not as callback. Callbacks would be OK except that the Mathworks
forgot to give us one for realloc. This leads to mixing memory managers
on the same pointers -- bad bad bad.
9/2/93 dhb commented out #include <TranslateLinefeeds.h> since it's
not presently compatible with MATLAB.
9/2/93 dgp Moved the NL and NEWLINE macros from Assign.c into this file.
9/8/93 dgp Mention VideoToolbox.c.
9/11/93 dhb,dgp Define STDIO_INT and STDIO_DOUBLE.
9/12/93 dhb Change STDIO_... to PRINTF_... and SCANF_...
Insert conditional for MATLAB 3.5 vs. 4.x
9/14/93 dhb Conditional for MATLAB changed to make symbol match major version number.
Removed traces of old trying to force 4 byte ints for MATLAB.
9/14/93 dgp Moved up inclusion of QuickDraw.h before MATLAB stuff, since cmex.h
requires it. Fixed typo, changing "#elseif" to "#elif".
9/15/93 dgp Edited the comments above, referring to VideoToolbox.c and the new
VideoToolboxMATLAB.c. (Deleted VideoToolboxMATLAB.c on 9/16/96.)
9/16/93 dgp Added contents of former Assign.h.
Defined MAC_C so that the VideoToolbox.h header may be used with
Standard C.
9/16/93 dhb Removed prototype for obsolete GetDateTimeString.
10/2/93 dgp Added #include <Errors.h>.
12/1/93 dgp Now always write "MATLAB" in all caps, since that's the trademarked name.
12/16/93 dhb Somewhere things got munged. Conditional for MATLAB version appeared
before inclusion of cmex, which won't work. I fixed the order.
12/16/93 dhb Commented out inclusion of TranslateLineFeeds.h down below. This
generates a link error from MATLAB.
12/29/93 dgp added #include <Packages.h>
6/12/94 dgp added definition of Apple's new BlockMoveData, for compatibility with
Apple's old pre-Universal header files.
6/12/94 dgp #include Strings.h if Universal header files are used.
7/28/94 dgp Added test for Metrowerks CodeWarrior C.
9/2/94 dgp #include MacMemory.h
9/5/94 dgp changed "int" to "short int" in definitions of PRINTF_INT and SCANF_INT for
MATLAB 4. This is based on common sense, not testing or detailed knowledge.
3/31/95 dgp As a gesture of support for Symantec THINK C 8, now define THINK_C.
5/26/95 dgp Formerly header files whose precompilation depends on the mc68881 or
mc68020 THINK C compiler options (i.e. math.h and mc68881.h) were omitted
from VideoToolbox.h so that the resulting precompiled header file could be
used in projects regardless of those options. However, for Metrowerks CodeWarrior
there's no advantage to omitting those headers, and a significant increase in
compile time, as fp.h is recompiled for each file. Since I've switch to
CodeWarrior, and expect most other users to switch as well, VideoToolbox.h now
includes math.h or fp.h.
5/27/95 dgp removed fp.c prototypes because Apple's fp.h now supports both 68k and ppc.
6/6/95 dgp discarded all references to TranslateLinefeeds.c and TranslateLinefeeds.h, since
I never got them to work properly, and I don't think they're needed with Metrowerks
CodeWarrior.
6/8/95 dgp Made sure that the MATLAB struct "Matrix" is always native aligned.
6/13/95 dgp define GENERATING68K, GENERATINGPOWERPC, and GENERATING68881 if not already
defined (as in Apple's latest universal headers). Define GENERATING68020.
6/14/95 dhb & dgp redefine the assert() macro, redirecting it to PrintfExit, which
in turn uses mex_error() to report the error. This is needed to get MEX files
to link properly.
6/16/95 dhb Fixed MATLAB's SCANF_INT etc. for __MWERKS__.
6/16/95 dgp moved the definitions of GENERATING68K to the top of this file, so that
the MATLAB conditionals can use them.
6/16/95 dhb & dgp now #include <assert.h>, unless MATLAB is defined, in which case
we define a MATLAB-compatible version of the assert macro. Just in case,
leave NDEBUG defined to disable the standard assert macro which may be
brought in if the user's source files #include <assert.h>.
6/16/95 dhb Fixed longstanding bug (in SCANF_INT??).
6/23/95 dhb Include prototypes for AfterDark.c and IsFileSharingOn.c.
7/19/95 dgp Added changes suggested by Stefan Treue, streue@bcm.tmc.edu, for compatibility
with Symantec C. Eliminated use of //-style comments. Now include math.h
when compiling for Standard C, i.e. MAC_C is false.
8/10/95 dgp Include MacMemory.h ONLY for THINK C, not for Symantec C, since I don't
have any reason to think that Symantec C memory management is bad.
8/13/95 dgp Removed definition of THINK_C for SYMANTEC_C. It seems better to leave
the compiler's macros alone. Changed conditionals throughout the VideoToolbox
to deal with all the special cases: THINK_C, THINK_CPLUS, and SYMANTEC_C.
3/5/96 dhb Add conditional to prevent inclusion of <fp.h> and instead include <math.h>
when THINK_C is true. This is needed to compile under THINK_C 8. I suspect
that this used to work because the universal headers variable was < 2.
4/1/96 dgp removed "MAC_C" requirement for inclusion of fp.h. Tried to make VideoToolbox.h
more consistent with q_include.h, so both will work separately or together, in
either order, but I haven't checked whether I succeeded.
8/29/96 dhb & dgp updated for compatibility with MATLAB 5.
8/31/96 dhb At dgp's suggestion, added macro mexFunctionEntry, which properly declares the
routine mexFunction according to which MATLAB version is being compiled. Note that
prhs is declared as inprhs so that you can set prhs = inprhs and then modify it
when compiling under version 5. This assignment needs to be done in all source files.
9/5/95 dgp if !UNIVERSAL_HEADERS, typedef UInt32 and UnsignedWide, and prototype Microseconds.
11/96 dgp changed argument name from "explicit" to "isExplicit" since "explicit" is keyword in C++.
12/23/96 dgp now set MATLAB to MATLAB_VERSION, if defined (i.e. version 5 on).
1/22/97 dhb Added prototype for IsAfterDarkEnabled.
1/25/97 dgp if MATLAB==4 #define mexWarnMsgTxt printf
2/17/97 dgp if MATLAB==4 #define mexWarnMsgTxt printf("%s",s)
3/4/97 dhb mexWarnMsgTxt conditionally uses TranslateEOL.
dhb Conditional macro for mexErrMsgTxt.
dhb Prototype for TranslateEOL.
3/5/97 dgp added Printf prototype. Polished the conditionals for THINK C MATLAB.
3/5/97 dgp as suggested by david brainard, removed the obsolete NL and NEWLINE stuff.
3/13/97 dgp I upgraded to the latest THINK C, from the Symantec C++ 8 release 5 CD-ROM.
(THINK Project Manager 7.05; "translator" THINK C 8.0 or 8.1d1.)
Symantec has announced that they will no longer develop C or C++, so this is
probably the LAST version of THINK C. In this release, Symantec changed math.h:
removing "pi", and screwing up the definition of "long double" so that <math.h>
generates a compiler error when you use the "native floating point" and "8 byte double"
settings that are required to generate a MEX resource file for MATLAB.
With David Brainard's help, I've added conditionals to VideoToolbox.h to
work around both limitations. Unfortunately this new version of VideoToolbox.h
may not be compatible with the <math.h> included by Symantec with earlier versions
of THINK C. Sorry, please blame Symantec, not me. Over the past year,
David and I have worked with three different versions of THINK_C, all with
different versions of <math.h>, that nevertheless all identify themselves by
setting the preprocessor symbol THINK_C to 7. That makes it really hard for a
simple header file to provide version-specific fixs. (The conditionals are
specific to THINK_C so other compilers won't be affected.)
3/19/97 dgp enhanced the VBLTaskAndA5 struct, removing the obsolete timer field, and adding
a new "seconds" field, as documented in VBLInstall.c
3/22/97 dgp the definition of mex_qd, used solely by THINK C MEX projects, has been moved from
here to CheckConfig.c in the Psychophysics Toolbox, which may be obtained from:
<http://www.psych.ucsb.edu/~brainard/software/>
3/27/97 dgp Updated the code defining GENERATING68881 to work with Apple's latest Universal Headers,
which now define that symbol, though they don't support THINK C. It now seems pointless
to retain support for Apple's pre-universal headers, so I've started stripping out
such code.

FIXED POINT ARITHMETIC
Apple defines a handy data type called Fixed that is stored in a long, but is
assumed to have a decimal point in the middle. Many operations, e.g. adding two
Fixed numbers or multiplying or dividing a Fixed by an integer, can be performed
directly. To multiply or divide two Fixed numbers use Apple's FixMul() and
FixDiv(). FixRatio(n,m) returns the Fixed ratio of two integers. Macintosh C
compilers define double in various ways, depending on whether a floating point
unit is to be used. The Apple-provided routines for doing type conversion to and
from Fixed are only appropriate if you are NOT using the floating point unit.
The ones defined below are faster and work with or without the FPU.
