Preview helps you inspect images and files without leaving the current workflow.
Open Preview
- Select an item in the file list.
- Double-click its thumbnail, or press Space after selecting it.
- Use the preview window to inspect the content.
- Press Esc or click the close button to exit.
What You Can Do in Preview
- View a larger version of the image.
- Zoom and pan to inspect details.
- Rotate when needed.
- Switch between nearby images.
- Check file information and image details.
- Set ratings or color labels.
Use Fit to Window to see the whole image, 1:1 for original-size detail, and the zoom slider to adjust magnification. Rotation changes the viewing direction temporarily. Compare places two images side by side. Available controls depend on the material being previewed.
Previewing Video Files
Select a video and use the Play Video action in the right details panel to open the in-app video player.
Common Cases
- If preview opens the wrong item, check the current selection.
- If Space does not open preview, first click to select one file.
- If a large image takes time to load, wait for the preview to finish loading.
- If video playback fails, first check that the original file is still accessible and has not been moved or deleted.
Multi-image files and keypoint details
From 3.13.31, image details follow the current preview page in multi-image files such as Excel and PDF. Wait for keypoint, color or pose details to load; a read failure is not evidence that parsing was never performed.
