Using Pyre

Pyre is the interactive registration tool. Install it with Installing Pyre on Windows, or run a developer build with Pyre development.

Open a registration with File → Open STOS, or File → New STOS for a new pair. Open a mosaic with File → Open Mosaic.

Control points

These bindings apply to STOS registration views. Triangulation transforms can add and delete points. A refined grid cannot; convert or use a triangulation transform if you need to edit the mesh.

Click to select a point.
Shift+Click to add a point.
Alt+Shift+Click to add a point and auto-align it.
Drag a point to move it.
Ctrl+drag to translate the mapped (source) image.
Alt+Click to move the selected point to the cursor.
Shift+right-click to delete a point (triangulation only).
Right-drag to pan.

Alignment keys

Rigid: Space runs a local brute-force refine (±5° at 1° steps) and keeps scale. Shift+Space also refines scale.
Mesh / RBF: Space auto-aligns the selected control point. Shift+Space auto-aligns all points.
Grid: Space auto-aligns the selected control point. Shift+Space runs one grid-refine pass (settings dialog, then a live preview). The Refine w/ Grid menu runs the chosen number of iterations as one job and updates the view after each pass. Several Shift+Space presses are not the same as that multi-pass job.

Navigation

WASD pans. Right-drag also pans.
The mouse wheel zooms.
Shift+scroll scales the transform about the cursor when the transform supports it.
Ctrl+scroll rotates the mapped section when the transform supports it. Ctrl+Shift+scroll uses finer steps. On a rigid transform, rotation is in the Composite view.
Page Up / Page Down changes magnification.
M matches Source, Target, and Composite to the focused window’s center and magnification.
L shows or hides mesh lines.
F flips the source (mapped) image.
Tab toggles how the source image is drawn (registered versus the alternate display) on the shared transform. It applies to Source, Target, and Composite.
Ctrl+Z undoes. Ctrl+X redoes.

Save with File → Save STOS.

If the window is blank, update the graphics driver. A developer build can try PYOPENGL_PLATFORM=software. Session logs for the installer build are under %LOCALAPPDATA%\Nornir\Pyre\logs.
