Class FileInspector

Namespace: LMKit.Inspection

Assembly: LM-Kit.NET.dll

Universal file metadata inspection: identifies ANY file from its leading magic bytes and extracts its metadata - image EXIF/GPS, video and audio stream summaries, PDF and Office document properties - into one stable FileInspection envelope.

Fast by construction: extractors perform bounded, header-only reads (chunk and box walks, targeted seeks), never a full decode - inspecting a multi-gigabyte video touches kilobytes. Every image format is parsed by the native imaging library (the same per-format parsers the codecs use), which probes headers and metadata without decoding pixels. PDF is routed through the SDK's existing pdfium metadata surface (PdfInfo).

Never throws on content: an unrecognized format still yields the identity layer, and malformed files yield whatever was readable plus Warnings. Only null arguments throw.

FileInspection info = FileInspector.Inspect(File.ReadAllBytes("photo.jpg"), "photo.jpg");
Console.WriteLine($"{info.Format} {info.Image?.Width}x{info.Image?.Height}");
foreach (MetadataProperty p in info.Properties)
    Console.WriteLine($"[{p.Group}] {p.Key} = {p.Value}");

Methods

Inspect(Attachment): Inspects an Attachment (the SDK's common input abstraction).

Inspect(byte[], string): Inspects in-memory content. fileName is optional and used only as an identification fallback for signature-less formats.

Inspect(Stream, string): Inspects a stream. A seekable stream is read in place with bounded, targeted reads; a non-seekable stream is buffered first.

Inspect(string): Inspects a file on disk.
