Module lightbox 

Lightbox image viewer: full-screen preview with zoom, pan, EXIF details, and keyboard navigation.

Loads preview or original resolution images with pinch-zoom and swipe navigation. Displays an EXIF metadata panel and provides download-to-folder and delete-to-trash actions.

Structs

LocalProbe 🔒

Everything we can learn about a local file off the main thread before handing the data back to GTK. exif is the cached EXIF parse; dims comes from a pixbuf header-only read; mtime_iso falls back when the file has no DateTimeOriginal so we always show some date.

Functions

accent_row 🔒

apply_lightbox_zoom 🔒

Apply zoom to a lightbox Picture. Zoom is fit-relative: 1.0 = the size the texture would occupy inside viewer under Contain layout. >1.0 overflows the viewer for panning. Returns the computed content dimensions when zoomed.

build_camera_group 🔒

build_image_group 🔒

build_location_group 🔒

drag_export_path 🔒

Create a properly-named export copy of a cached file for drag-out.

exif_from_local 🔒

Project local-file metadata into the API EXIF shape so the existing renderer handles both sources uniformly.

fill_exif_box 🔒

Populate the details sidebar with sectioned EXIF metadata.

format_bytes 🔒

Format a byte count value into a human-readable size string (e.g. KB, MB, GB).

format_camera 🔒

format_datetime_display 🔒

Format an ISO 8601 timestamp for display, converting from UTC to the user’s local timezone.

format_exposure 🔒

format_location 🔒

open_lightbox 🔒

Construct and present the fullscreen lightbox view for a selected asset.

original_preview_cache_path 🔒

systemtime_to_rfc3339 🔒

Render a SystemTime as an RFC3339 string in the local timezone so the existing format_datetime_display pipeline can format it consistently with EXIF-derived timestamps.

truncate_filename 🔒

Truncate a filename to a maximum character limit, appending an ellipsis if needed.
