The colour-profile struct and the maths over it: the derived matrix/LUT engine.
Layer 2: nothing here mentions dt_develop_t, dt_dev_pixelpipe_t or dt_iop_module_t, and the four forward declarations that used to sit here – the only reason this header reached two layers up – went with the pipeline-facing half to develop/iop_profile.h.
pixel/rgb_norms.h and pixel/colorequal_shared.h consume this half, which is why it could not simply move up to develop/ with the rest. (pixel/eaw.c was named here too, but as of this writing it includes nothing from colorprofiles/ and names no type declared below.)
Two things live here, and only these two:
cmsHPROFILE once, so that the pixel loop never calls lcms2 per pixel. Extracting them is expensive (two 65536-entry passes) and is a pure function of (type, filename), so dt_colorspaces_add_profile() memoises the result process-wide;No cmsHPROFILE and no cmsHTRANSFORM ever crosses this header, by design. There is no cmsDupProfile in lcms2 – the only true deep copy is serialise-and-reopen (~0.005 ms for a built-in, but 1.02 ms for a real colord display profile), and copying a prepared transform means rebuilding it (2.2-38 ms, not amortised). So the lifetime of an lcms2 handle is answered by a lock, not by a copy: dt_colorspaces_lock_profiles() / dt_colorspaces_unlock_profiles() in colorprofiles/colorspaces.h. The functions below that need one take that lock themselves, internally, and only for the one profile that can change under them (DT_COLORSPACE_DISPLAY).
Definition in file colorprofiles/iop_profile.h.
The three colorspace kernels, compiled once and held by common/opencl.c.
Built from colorspaces.cl (program 23 in data/kernels/programs.conf) by dt_colorspaces_init_cl_global(), reached from the pixel loops as a file-static in colorprofiles/iop_profile.c. Members are kernel handles, not pointers.
The device-side view of a dt_iop_order_iccprofile_info_t: the scalar fields only.
Flattened for upload as a constant buffer. The two matrices are stored as 9 contiguous floats, NOT as the host struct's 4x4 padded dt_colormatrix_t; the curves are not here at all – they travel separately as a float image built by dt_ioppr_get_trc_cl(). The host identity (type, filename, intent) is dropped: the kernels only do arithmetic.
dt_colorspaces_iccprofile_info_cl_t in data/kernels/colorspaces.cl – there is no compile-time check on either side. A profile reduced to the arithmetic the pixel loop can run: two matrices and six tone-curve LUTs, plus the identity they were derived from.
This is the DERIVED form of a profile, not the profile. It is produced once by dt_colorspaces_add_profile() from the cmsHPROFILE that colorprofiles/colorspaces.c owns, and from then on it is self-contained: nothing in it points back at lcms2, so the pixel loops below need no lock and no lcms2 call per pixel.
lut_in[3] + lut_out[3]), see dt_ioppr_init_profile_info(). develop/blend.c shallow-memcpys the struct onto the stack (dt_develop_blendif_init_masking_profile()), which ALIASES those six pointers into a second struct. Such a copy is read-only borrowed state: it must never be handed to dt_ioppr_cleanup_profile_info(), and the original must outlive it. Only the allocator of an instance may free it.isnan(matrix_in[0][0]) means "not a matrix-shaper profile, use lcms2" (dt_ioppr_mark_as_nonmatrix_profile()), and lut_x[c][0] < 0.0f means "channel c has no
tone curve, treat it as linear" (dt_ioppr_clear_lut_curves()). Code that memsets or calloc's one of these structs instead of calling dt_ioppr_init_profile_info() gets the opposite meaning for both.

Evaluate the power-law continuation of a tone curve past white: b * (a*x)^c.
Apply one channel's tone curve to each of the three colour channels, or pass the channel through untouched when it has none.
| coeff | the {a, b, c} fit from dt_ioppr_init_unbounded_coeffs(), i.e. one row of unbounded_coeffs_in/_out. |
| x | input value, expected >= 1.0. |
| rgb_in | source pixel. |
| rgb_out | destination pixel. Only channels 0..2 are written – the 4th lane is left alone, which is what preserves alpha through an in-place conversion. |
| lut | the profile's lut_in or lut_out. A NULL entry, or one whose [0] is negative, means "channel is linear" and is copied straight through. |
| unbounded_coeffs | the matching unbounded_coeffs_in/_out. |
| lutsize | entry count. |
Sample a tone curve, with linear interpolation between entries.
| lut | curve, lutsize entries spanning [0,1]. |
| v | input value. |
| lutsize | entry count. |
v is clamped into the table, so everything above 1.0 returns the last entry. Extrapolation past white is eval_exp()'s job, and dt_ioppr_eval_trc() is the one that picks between them. Evaluate a tone curve over the whole real line: table below white, power law above.
| x | input value. |
| lut | the curve, one of lut_in[c]/lut_out[c]. |
| coeff | the matching unbounded_coeffs_*[c] fit. |
| lutsize | entry count. |
lut[0] < 0 "linear channel" sentinel – callers must, or a linear channel gets read as a curve whose first entry is -1. _apply_trc() and the loops in the .c do that test. | dt_iop_order_iccprofile_info_t * dt_colorspaces_add_profile | ( | const dt_colorspaces_color_profile_type_t | profile_type, |

Find-or-build the derived matrix/LUT data for a profile identity, memoised.
Deriving matrices and curves from a profile costs two 65536-entry extractions and is a pure function of (type, filename, intent), so the result is kept in a process-wide memo. The lookup and the append are ONE critical section under the module's own mutex: this is reached from the pipeline worker (iop/lut3d.c and iop/tonecurve.c call it from process()/process_cl(), once per tile) and from the GUI thread (iop/colorin.c), and two threads missing the same key concurrently would otherwise each build an entry – 1.5 MB of tone-curve LUTs apiece – and append both. Building the DT_COLORSPACE_DISPLAY entry additionally takes dt_colorspaces_lock_profiles() internally, for the whole span from resolving the handle to the last extraction, because that handle is the one datum in the profile list that is replaced at runtime.
| profile_type | profile identity; half of the memo key. |
| profile_filename | ICC file name, "" for built-ins; the other half of the key. |
| intent | rendering intent; the third part of the key. It is stored in the entry and read back by the lcms2 transform path, so a memo that ignored it handed the second caller a transform built for the first caller's intent – silently, and depending on which module happened to commit first. Two intents for one profile now cost two entries, which is 1.5 MB each; that is the price of the answer being right. |
(type, "") they would all collide on one entry and stomp each other across images. They live on the pipe that built them instead (dt_dev_pixelpipe_t.owned_input_profile_info); see dt_ioppr_set_pipe_input_profile_info() in develop/iop_profile.c.

Convert a 4-channel float buffer between RGB and Lab through one profile.
THE entry point for the RGB <-> Lab leg of the pipeline, called by develop/pixelpipe_cpu.c around every module that wants a different working space than the one the pipe carries. It dispatches on the profile itself, not on a caller's request: if the profile reduced to real matrices (!isnan(matrix_in[0][0])) it runs dt_ioppr_transform_matrix() – our own vectorised matrix + tone-curve LUT loop, with power-law extrapolation above white; otherwise (a CLUT profile, a v4 parametric curve lcms2 will not reduce) it falls back to dt_ioppr_transform_lcms2(), which builds a cmsHTRANSFORM and runs cmsDoTransform. Callers do not choose, and do not see which ran except in the -d perf trace.
The lcms2 branch resolves and pins the profile handle itself – it takes dt_colorspaces_lock_profiles() around resolve-through-cmsCreateTransform when the profile is DT_COLORSPACE_DISPLAY – so callers neither take that lock nor need to know the branch exists.

OpenCL counterpart of dt_colorspaces_apply_profile(), same contract.
Same internal branch, different fallback cost: a matrix profile is uploaded (the scalar fields as a constant buffer, the six curves as a 256 x 1536 float image) and converted by the colorspaces_transform_* kernels; a non-matrix profile has no kernel, so the buffer is read back to host memory, run through dt_colorspaces_apply_profile() on the CPU in place, and written back to the device.

Drop the memoised DT_COLORSPACE_DISPLAY entry, whose source profile this module replaces on a monitor change.
Nothing invalidated it before, so a session kept the previous monitor's matrices and tone curves for as long as the memo lived. That was already wrong when the memo hung off one image; now that it is process-wide it would persist for the whole run. Dropped rather than rebuilt: the next caller that wants it will build it, and rebuilding here would mean deriving a profile under the memo lock from inside the profile-changed handler.

This owns the WHOLE teardown, not just the LUTs.

Convert a 4-channel float buffer between two RGB profiles.

Same internal dispatch, on all four matrices this time: when both profiles reduced to matrices, the two 3x3s are pre-multiplied ONCE into a single matrix so the loop costs one matrix product per pixel instead of two; otherwise both profiles go to lcms2 as a single RGB->RGB transform.

OpenCL counterpart of dt_ioppr_transform_image_colorspace_rgb().
Same dispatch: both profiles reduced to matrices means one pre-multiplied matrix and the colorspaces_transform_rgb_matrix_to_rgb kernel; otherwise the buffer is read back, converted on the CPU by dt_ioppr_transform_image_colorspace_rgb(), and written back.

The lcms2 branch of dt_colorspaces_apply_profile(): RGB <-> Lab via cmsDoTransform.
Resolves the profile by identity out of the shared list, builds a cmsHTRANSFORM, runs it over the buffer and deletes it – so the transform is rebuilt on EVERY call, which is why this is the fallback and not the default. It takes dt_colorspaces_lock_profiles() itself, across resolve-through-cmsCreateTransform, when the profile is DT_COLORSPACE_DISPLAY, because that handle can be closed and replaced by a monitor change mid-flight.
| op | module op string, for the -d dev trace only. |
| multi_name | module multi_name string, same. |
| image_in,image_out | 4-float pixels; may be the same buffer. |
| width,height | buffer geometry. |
| cst_from,cst_to | source and destination colorspaces. Only RGB <-> Lab is supported; anything else leaves *converted_cst == cst_from and logs to stderr. |
| converted_cst | out: cst_to on success, cst_from on refusal. |
| profile_info | profile identity to resolve. Only type, filename and intent are read – the matrices and LUTs are ignored on this path. A type of DT_COLORSPACE_NONE silently substitutes linear Rec2020 here, unlike dt_colorspaces_apply_profile(), which refuses it before ever getting this far. |

The vectorised branch of dt_colorspaces_apply_profile(): RGB <-> Lab by matrix and tone-curve LUT.
No lcms2, no lock, no per-call setup: it reads the matrices and curves already in profile_info and runs an OpenMP/SIMD loop. Preserves the 4th float of each pixel on the Lab -> RGB leg (some callers convert in place and rely on alpha surviving).
