_lib_snapshot_capture_state()

static int _lib_snapshot_capture_state ( dt_lib_snapshot_t *  snapshot, dt_develop_t *  source  )

static

Freeze the current darkroom develop state into one snapshot-local develop context.

This deep-copies the in-memory history stack and module order from the live darkroom context, so each snapshot remains stable even if the user later edits darktable.develop or rewrites history in the database.

Parameters

snapshot	destination snapshot slot.
source	live darkroom develop context.

Returns

int 0 on success, 1 on failure.

_lib_snapshots_refresh_pipe_image()

static int _lib_snapshots_refresh_pipe_image ( dt_lib_module_t *  self, dt_lib_snapshot_t *  snap  )

static

Recompute the selected snapshot image from a dedicated preview pipe at one history fence.

We intentionally process a preview-style full-image buffer and keep it in a cairo surface. This lets ROI pan/zoom updates reuse the same pixels through the darkroom transform only, so interactive navigation does not trigger expensive snapshot recomputations.

Parameters

self	snapshots lib module.
snap	selected snapshot metadata.

Returns

int 0 on success, 1 on failure.
