3.2 Rendering Pipeline
- File Identification – The provider inspects the file’s magic number and extension to select the appropriate decoder.
- Decoder Invocation – ST employs a modular codec library (
STCodec) that bundles open‑source components (e.g., libjpeg‑turbo, libavcodec, Poppler for PDFs). The library is compiled with /MT to avoid runtime dependencies. - Pre‑Processing – For image files, EXIF orientation is applied; for videos, the mid‑frame (or user‑specified timestamp) is extracted.
- Scaling & Color Management – The image is transformed into a 32‑bit BGRA bitmap using WIC (Windows Imaging Component), then scaled with Lanczos‑3 filtering for the HQ mode. Color profiles are preserved via ICC conversion to the system display profile.
- Overlay Composition – Using GDI+, the overlay icons/text (duration, page count) are rendered onto the bitmap.
- Caching – The final thumbnail is stored in the per‑folder cache (a SQLite DB). The cache entry includes a hash of the file’s last‑write timestamp and a SHA‑256 of the first 1 KB to detect modifications.
