  1. Select Try example to see a complete photo horizon and vertical guide workflow. Open supported still PNG, JPEG or WebP images. Geometry and source markers can be edited in the workspace.
  2. Adjust the labelled controls or open Input/Geometry to change the evidence. Run workflow applies the current input; undo and redo restore text/settings decisions.
  3. Inspect Original and Result, using source markers where supported. Findings describe cases that need review; missing evidence remains unknown.
  4. Open Export for task artifacts, JSON/CSV results or a complete ZIP. Save project keeps input/settings; projects with local binary files need their original files to be reselected when reopened.
