Capture History
The History Window (700 × 500) holds every capture Tex has taken, as a grid of thumbnails in reverse chronological order. Open it from the History button in the main toolbar.
Browsing and Loading
- Thumbnails are laid out newest-first.
- Click any thumbnail to load that capture into the main editor — annotations, OCR, save, everything.
- The window is resizable; the grid reflows to the width.
Captures are added to history automatically as they happen — no explicit save step.
Stored Metadata
Each history item keeps:
| Field | Notes |
|---|---|
| Id | Internal GUID. |
| Timestamp | Capture time. |
| Filename | Original filename if saved to disk. |
| Size | Byte size. |
| Format | PNG / JPEG / BMP / WebP. |
| Dimensions | Width × height in pixels. |
| OCR results | Any OCR runs attached to this capture (04.04). |
Persistence Settings
Setting — History.PersistToDisk (default true). When on, history survives app restart. Setting — History.MaxItems (default 50). Maximum number of captures to keep. Setting — History.MaxSizeMB (default 200). Maximum total size on disk.
The history file lives at:
%APPDATA%\Tex\capture_history.jsonThumbnails are stored alongside it. Deleting this file is safe — Tex will recreate it on next launch.
Rolling Eviction
Warning — When MaxItems or MaxSizeMB is reached, Tex drops the oldest captures first to make room for new ones. There is no undo and no prompt. If a capture is important, save it to disk (Ctrl+S) or pin it (07.03) so you don't lose it to eviction.
Sensible tuning:
| Usage pattern | MaxItems | MaxSizeMB |
|---|---|---|
| Light — a few captures per day | 50 (default) | 200 (default) |
| Heavy — dozens per session | 200 | 1000 |
| Memory-tight machine | 25 | 100 |
