PhotoCraft reads GIMP's .xcf (and .xcf.gz) files, read only, through a new
reader in photocraft-io written from the public XCF specification: versions
0 to 26, uncompressed, RLE and zlib tiles, 8/16/32-bit integer and
16/32/64-bit float precisions (linear precisions get a linear profile),
pixel layers at any position, groups by item path with pass-through,
layer masks applied or disabled, opacity, visibility, locks, colour tags,
the 2.10 and legacy blend modes mapped to Photoshop's (modes without an
equivalent open as Normal with a note), the ICC profile, resolution,
guides, the comment, extra channels and the saved selection; indexed
images open as RGB. Text, vector and link layers open as their pixels;
layer effects, paths and floating selections are reported.
Fixtures are written by GIMP 3.2 itself (scripts/xcf_fixtures.py), each
with GIMP's merged rendering as a PNG. In gamma-encoded blend and
composite spaces our composite matches GIMP within 0.5/255; GIMP's
linear-light default, its Clip to backdrop and its clamp-after-alpha
for unbounded modes are documented and measured in docs/xcf.md.
Calls storytold/craft-common-actions/.github/workflows/sonarcloud.yml@main
with secrets: inherit. Adds SonarCloud badge to README where missing and
removes the redundant sonar-project.properties (config now passed by the
reusable workflow).
- Replace whole-region Vec<f32> read_region/write_region in CutParts::new
with tile-parallel cut_piece + try_fill_surface/try_clear_surface,
sharing interior Arc<Tile> allocations in O(1) and activating the
solid_tile hole-fill fast path on Background and mask targets.
- Cache piece_bounds on CutParts so CutParts::place avoids scanning tile
content bounds on every drag frame.
- Parallelize composite_over across top tiles with Rayon and share fully
opaque top tiles by Arc<Tile> clone in O(1), preserving COW tile
identity for GPU canvas uploads.
- Parallelize Surface::translated across target tiles with Rayon and
prune cleared tiles in-place inside edit_tiles.
- Skip zero-offset floating preview generation on pointer-down in
move_ui::floating_doc.
- Exclude SnapKind::Selection when moving selected pixels with the Move
tool so small initial drags do not snap back to (0, 0).
- Keep navigator_plain active during Move/Brush/Patch drags on a GPU
canvas so navigator_gpu is not evicted into a synchronous full-document
CPU thumbnail composite on the first drag frame.
- Parallelize row normalization in compose::render_reduced_in_bands and
add a direct read_rgba_into fast path for unmasked Normal layers over
an empty backdrop.
#7125 keeps existing type's pixel size across Image Size, so the #6491 test's 12 pt layer, made before the change to 144 ppi, became 6 pt. The test now creates its layer at 144 ppi; its assertions are unchanged.
