From 11455e0fe9f7f74a1411065ccab815293de149c0 Mon Sep 17 00:00:00 2001 From: loyet Date: Fri, 16 Oct 2026 10:44:29 +0200 Subject: [PATCH 1/3] M1: .fig import reads images carried in the message (image.dataBlob) Copies written by plugins and tools carry their image bytes in the message: a paint's image.dataBlob indexes the message's blobs. A bare canvas (what the clipboard holds, see #647) has no images/, so these fills came in as grey placeholders. The importer now falls back to the embedded bytes, keyed by image hash, after the archive's images/. Blobs over the image size cap and indexes past the blobs are skipped and stay placeholders. Tests: a bare canvas carrying its image in a blob, and a dataBlob past the blobs. --- crates/format/src/fig/mod.rs | 43 ++++++++++++++++++++++++++--- crates/format/src/fig/tests.rs | 49 +++++++++++++++++++++++++++++++++- docs/file-format-parity.md | 5 ++-- 3 files changed, 91 insertions(+), 6 deletions(-) diff --git a/crates/format/src/fig/mod.rs b/crates/format/src/fig/mod.rs index ec2a0e23..091492da 100644 --- a/crates/format/src/fig/mod.rs +++ b/crates/format/src/fig/mod.rs @@ -6,7 +6,8 @@ //! zstd: a binary schema in the kiwi format ([`kiwi`]), then a message encoded with it.
