* craft-cms: the changes PhotoCraft made to its copy since extraction PhotoCraft kept editing crates/cms after craft-cms was extracted from it at storytold/photocraft@b3222ee8. This ports its 41 commits up to storytold/photocraft@0143b148 with a three-way merge per file, keeping the changes craft-cms made on its own (Result-returning API, white preservation, FOGRA39, named colours, profile ID). Ported: the .3dl shaper, Mesh header, UTF-16 and .look fixes in lutfile; the checked ICC offsets and the per-profile curve sample budget; same_bytes and the byte-confirmed transform cache; the blocked matrix/TRC path and the 8-bit first-stage table; GpuMatrixShaper; cicp_rgb; the ACEScg and Dot Gain 20 % built-ins (the latter now the default gray); bisection for a table's flat ends; PhotoCraft spelled with a capital C in the built-in descriptions, with the shipped coated CMYK profile's bytes as PhotoCraft regenerated them. Not taken, because craft-cms already does it another way: Curve::inverse_table (inverse64_many), the effective-dimension loop in multilinear interpolation, the curve-count and mluc checks, and the .cube DOMAIN writer. The 8-bit first-stage table checks device white as the exact path does. Refs #779 * craft-cms: Lut3d::from_fn PhotoCraft's proof and HDR display tables are built from a chain of several transforms, which it wrote into Lut3d's fields. Those are private here, so from_fn samples any RGB function, with the same size bounds as from_transform. Refs #779 * craft-cms: README names Lut3d::from_fn * craft-cms: a UTF-8 byte-order mark before a .cube or .3dl file is skipped A LUT file saved with a UTF-8 BOM failed to parse: the mark stayed on the first keyword. decode_text now strips it, as it already handles UTF-16. Ported from storytold/photocraft#9776. * craft-cms: a .cube data line with a field that is not a number is an error A data line's fields after the first were parsed with filter_map, so '0.25 nope 0.5 0.75' silently became the three numbers that did parse. Every field must now parse. Ported from storytold/photocraft#10112. * craft-cms tests: .look data is pinned to hand-written little-endian bytes The test built its input with the same to_le_bytes the parser mirrors, so a wrong byte order on both sides would pass. The bytes are now written out. Ported from storytold/photocraft#10389. * craft-cms: a 1D .cube whose domain the 33-point bake cannot hold is refused A 1D LUT is resampled onto a fixed 33-point grid. A steep curve over a narrow DOMAIN_MIN/DOMAIN_MAX (or LUT_1D_INPUT_RANGE) does not survive that: a two-node ramp over 0.24..0.26 baked 42 RGB8 levels off. The parser now measures the baked table against the exact curve for a non-default domain and refuses one that shifts by more than two RGB8 levels, naming the channel. Default-domain tables and gentle curves are unchanged. Ported from storytold/photocraft#9101. * craft-cms: only a quote that opens a .cube TITLE protects '#' A quote anywhere on a TITLE line made the text up to the next quote part of the title, so 'TITLE Look # "draft"' took its comment into the title. Only a quote at the start of the value opens a quoted title now; an unterminated one is an error, and an unquoted title ends at '#' like any other line. Ported from storytold/photocraft#8506 (its lutfile.rs part). * craft-cms: GamutCheck::mask_rgba computes a whole gamut-warning mask in parallel A caller building a gamut-warning mask made one delta_e call per pixel on one thread. mask_rgba fills the mask (255 where alpha > 0 and the pixel is out of gamut) in 16K-pixel chunks on the rayon pool, serial below that and on wasm, and returns the count. The result is identical to out_of_gamut per pixel. A check not built from an RGB source profile is refused before anything is written, since an RGBA pixel cannot stand for a CMYK, gray or Lab colour. Ported from storytold/photocraft#9748. --------- Co-authored-by: NetterSilver <133535268+Silvertree2010@users.noreply.github.com> Co-authored-by: Max Mittelstädt <62167861+TheGalitube@users.noreply.github.com> Co-authored-by: smittie2000 <smittie2000@gmail.com> Co-authored-by: bfenty <1398236+bfenty@users.noreply.github.com> Co-authored-by: FredApps <153173854+FredApps@users.noreply.github.com> Co-authored-by: vangel76 <vangel1976@googlemail.com>
