- effectcraft-psd (L1): PSD/PSB reader from Adobe's published file format spec (layers, groups, masks, blend modes, text engine data, lfx2 effects, fill/adjustment layers, vector masks; 1/8/16/32-bit, RGB/CMYK/Gray/Lab/Indexed, raw/RLE/ZIP) and a minimal writer for fixtures. - File > Import: importAs footage|composition|compositionLayerSizes, layer (Choose Layer); groups -> precomps (pass-through collapses), text -> editable text, styles -> Layer Styles, adjustments -> adjustment layers with effects; UI asks the Import Kind for Photoshop files. - effectcraft-svg (L2): SVG parser (shapes, paths, transforms, use, CSS, gradients) and rasteriser; .svg imports as footage, continuously rasterised when the switch is on. - layer.create: shapesFromVector, shapesFromText, masksFromText, editableText (stub removed). - Disk cache (render::disk_cache): LZ4 content-keyed frames and layer buffers, LRU size limit from prefs, atomic writes, restart persistence; edit.purge clears it, cache.diskStats query; viewer frames read/write it and the timeline shows disk-only frames in blue.

# effectcraft-psd
|
|
|
|
Reads Photoshop documents (`.psd`, and `.psb` large documents) for File ▸ Import (as footage, as a
|
|
composition, or as a composition with layer sizes retained), and writes a minimal subset (used to
|
|
generate test fixtures).
|
|
|
|
Implemented from Adobe's public **Adobe Photoshop File Formats Specification** (November 2019
|
|
edition): file header, colour mode data, image resources, layer and mask information (layer
|
|
records, channel image data, layer mask data, additional layer information: `luni`, `lsct`/`lsdk`,
|
|
`lyid`, `iOpa`, `TySh`, `lfx2`, `SoCo`, `nvrt`, `brit`, `hue2`, `levl`, `expA`, `vmsk`/`vsms`,
|
|
`Lr16`/`Lr32`), the descriptor (action) structure, and the merged image data. Raw, RLE (PackBits)
|
|
and ZIP (with and without prediction, inflated with `miniz_oxide`) compression; 1/8/16/32-bit;
|
|
Bitmap, Grayscale, Indexed, RGB, CMYK (naive conversion) and Lab colour modes.
|
|
|
|
Text engine data (`EngineData`) is read best-effort for the font, size, fill colour and
|
|
justification of the first style run. No Adobe code, sample files or assets were used; test
|
|
fixtures are generated in-test by the writer in this crate ([`write`](src/write.rs)).
