// Little cms
3
4
// Chameleonic header file to instantiate different versions of the
5
// transform routines.
6
//
7
// As a bare minimum the following must be defined on entry:
8
//   FUNCTION_NAME             the name of the function
9
//
10
// In addition, a range of other symbols can be optionally defined on entry
11
// to make the generated code more efficient. All these symbols (and
12
// FUNCTION_NAME) will be automatically undefined at the end of the file so
13
// that repeated #includes of this file are made simple.
14
//
15
// If caching is wanted, define CACHED.
16
//
17
// If the representation/calculations are to be done using floating point
18
// define XFORM_FLOAT. In the absence of this it is assumed that the
19
// calculations will be done in 16 bit with appropriate unpacking/repacking.
20
//
21
// If you know the number of input/output channels, define NUMINCHANNELS and
22
// NUMOUTCHANNELS.
23
//
24
// If you know the number of bytes used for the packed version of input and/or
25
// output, define INPACKEDSAMPLESIZE and OUTPACKEDSAMPLESIZE.
26
//
27
// If you do not know the number of channels and/or the sample size, but you
28
// do know a maximum bound on the number of bytes used to represent the
29
// unpacked samples, then operation with CACHE can be accelerated by defining
30
// CMPBYTES to the number of bytes that should be compared to the cached result.
31
// Usually that is calculated from NUMINCHANNELS and INPACKEDSAMPLESIZE, so
32
// specifying it directly is only useful if either (or both) of those is not
33
// known in advance.
34
//
35
// For Premultiplied Alpha modes, you must define PREMULT. We only support
36
// premultiplied alpha where the alpha is the last 'extra' channel, and
37
// where both source and destination are packed in the same way.
38
//
39
// If you know the code to be used to unpack (or pack, or both) data to/from
40
// the simple 16 bit transform input/output format, then you can choose
41
// to this directly by defining UNPACK/PACK macros as follows:
42
//   UNPACK(T,TO,FROM,SIZE,AL) (Opt)   code to unpack input data (T = Transform
43
//                                     TO = buffer to unpack into, FROM = data,
44
//                                     SIZE = size of data, AL = Alpha)
45
//   PACK(T,FROM,TO,SIZE,AL)   (Opt)   code to pack transformed input data
46
//                                    (T = Transform, FROM = transformed data,
47
//                                    TO = output buffer to pack into,
48
//                                    SIZE = size of data, AL = Alpha)
49
//
50
// Ignore AL unless PREMULT is defined, in which case it will be in the packed
51
// format. AL is guaranteed to be non-zero.
52
//
53
// If UNPACKINCLUDESPREALPHA is defined, then UNPACK should undo the
54
// premultiplication by AL (i.e. divide by AL). Otherwise AL should be ignored
55
// and this routine will do it for you.
56
//
57
// If PACKINCLUDESPREALPHA is defined, then PACK should apply AL (i.e. multiply
58
// by AL). Otherwise AL should be ignored and this routine will do it for you.
59
//
60
// As an alternative to the above, if you know the function name that would
61
// be called, supply that in UNPACKFN and PACKFN and inlining compilers
62
// should hopefully do the hard work for you.
63
//   UNPACKFN          (Opt)   function to unpack input data
64
//   PACKFN            (Opt)   function to pack input data
65
//
66
// If the data happens to be in the correct input format anyway, we can skip
67
// unpacking it entirely and just use it direct.
68
//   NO_UNPACK         (Opt)   if defined, transform direct from the input
69
//                             data.
70
//
71
// UNPACK/PACK/UNPACKFN/PACKFN/NO_UNPACK are all expected to update their
72
// TO pointer to point to the next pixels data. This means for cases where
73
// we have extra bytes, they should skip the extra bytes too!
74
//
75
// If the data happens to be in the correct output format anyway, we can skip
76
// packing it entirely and just transform it direct into the buffer.
77
//   NO_PACK           (Opt)   if defined, transform direct to the output
78
//                             data.
79
//   COPY_MATCHED(FROM,TO)(Opt)if defined, copy output values from FROM to
80
//                             TO. Used in the case CACHED case where the
81
//                             cache matches and we have to copy forwards.
82
//
83
// GAMUTCHECK can be predefined if a gamut check needs to be done.
84
//
85
// If there are a known number of extra bytes to be dealt with, define EXTRABYTES
86
// to that number (such as 0 for none).
87
// If you want to provide your own code for copying from input to output, define
88
// COPY_EXTRAS(TRANS,FROM,TO) to do so.
89
// If none of these are defined, we call cmsHandleExtraChannels.
