# Annotate Your First Images – LumiScan Annotation Web

This guide takes you from signing in to your first saved annotations. You need the address of the server (for example `https://annotation.example.com`) and an account; your administrator gives you both.

## 1. Sign in

1. Open the address in Chrome, Edge or Firefox.
2. Sign in:
   - with your user name and password, or
   - with **Sign in with …** when your company uses single sign-on.
3. At the first sign-in with a local account you choose your own password (at least 10 characters).

## 2. Open a project and an image

1. In the top bar, choose the **Project**. Only projects you take part in are listed; with only one, the list is hidden.
2. Choose the **Folder**, usually one folder per day of recording.
3. Click an image in the list on the left. Images with a filled dot have boxes already.

## 3. Draw a box

Boxes are drawn as a [center-line rectangle](https://docs.hdvisionsystems.com/en/lumiscan-annotation-web/2.3.0/annotating-images.html#center-line-rectangle): the center line from bottom to top, then the width.

1. Choose the label first: click it in the **Labels** list on the right, or press its number key.
2. Double-click the image where the **bottom** of the object is (or press `N` and click).
3. Click where the **top** of the object is. This draws the center line and sets the height and the angle.
4. Move the mouse sideways and click again. This sets the width on both sides of the center line.

| Click bottom, move to the top | Click top, move sideways | Click: the box is finished |

The green edge is the **bottom** of the box. Draw every object of a kind in the same direction, for example bottom always where the part lies flat. The network learns this direction.

> [!TIP]
> The magnifier next to the mouse pointer shows the pixels under it, enlarged, with the position to 0.1 pixel. Switch it off and on with `M`.

## 4. Correct a box

- Drag the box to move it, drag an edge to resize it, drag a corner to rotate it.
- Keys: arrow keys move by 1 pixel (with `Shift` 10 pixels); see [Keyboard Shortcuts](https://docs.hdvisionsystems.com/en/lumiscan-annotation-web/2.3.0/keyboard-shortcuts.html).
- Number keys 1 to 9 change the label of the selected box.
- Right-click or `Delete` deletes the selected box. `Ctrl+Z` undoes.

## 5. Save and continue

- **Save** (`S`) writes the boxes. The status in the top bar confirms it, for example **Saved part_002.png**.
- **Save and copy to next** (`Alt+S`) saves, opens the next image and copies the boxes onto it: useful for image series where the parts barely move.
- `A` and `D` open the previous and the next image. If you have unsaved changes, you are asked first.
- **Only images without boxes** shows what is left to do.
