Compositor for Windows 0.1.7
Pre-releaseThis independent Windows 11 x64 preview continues from 0.1.6. It is based on Compositor 1.0.4 by Robbie Tilton at a19db9011282399785dc18efcfded904627bdcc2. The port does not imply upstream endorsement, and full Mac equivalence is not claimed.
Navigator
When zoom or pan leaves part of the document off-screen, a navigator appears at the bottom-right of the canvas. It shows the whole composite and a rectangle for the visible area. Click or drag inside it to move the view. The picture updates shortly after editing pauses. A brush or retouch stroke keeps the current picture until the stroke ends. Fit (Ctrl+0) hides it when the whole document is on screen.

The mouse wheel pans, including with Ctrl. Alt and rolling the wheel forward zooms in, and backward zooms out, around the pointer. One notch multiplies or divides the zoom by 1.25.
Layers and Camera Raw
Dragging a layer keeps that layer on screen while its preview finishes. A later drag does not reuse the previous layer's preview. Auto-select layer starts checked.
Camera Raw guided-upright lines stay visible on the preview, aligned with the image while zooming or panning, including a moved, rotated, or flipped layer. Clear Guides, Cancel, and OK remove them. The upright calculation is unchanged.
Limits
Downloads are unsigned. Updates are manual. Full Mac equivalence, reciprocal .comp exchange, and Photoshop compatibility remain unverified. Keep a copy of each complete .comp directory. See KNOWN-ISSUES.md for brush performance, background removal, and the checks that have not been run on a fresh Windows install.
