Single Image File (Ctrl+I): Supports importing various formats such as *.jpg, *.png, *.bmp, *.webp, and *.tif.
Single Video File (Ctrl+O): Supports importing video formats such as *.mp4, *.avi, *.mov, *.mkv, *.wmv, and *.flv.

1.2 Data Deletion

X-AnyLabeling provides data deletion functionalities as follows:

Delete Label File (Ctrl+Delete): Deletes the current annotation file. This operation cannot be undone, so please proceed with caution.
Delete Image File (Ctrl+Shift+Delete): Deletes the current image file, moving it to the _delete_ folder within the current image directory.

1.3 Image Switching

In X-AnyLabeling, in addition to regular image switching operations, the following methods are also supported:

Shortcut	switch_to_checked	Description
Ctrl+Shift+A	true	Jump to the previous annotated image
Ctrl+Shift+D	true	Jump to the next annotated image
Ctrl+Shift+A	false	Jump to the previous unannotated image
Ctrl+Shift+D	false	Jump to the next unannotated image

You can determine the switching mode by modifying the switch_to_checked field in the user configuration file.

Additionally, you can jump to a specific image by entering the image name in the file search bar at the bottom right of the interface and pressing Enter.

1.4 Saving Label Data

X-AnyLabeling has an auto-save feature enabled by default. Upon initial startup, users can check if the Auto Save option is selected from the File dropdown menu.

Label files are saved in the current image directory in *.json format, with the following template:

{
  "version": "${version}",
  "flags": {},
  "shapes": [
    {
      "label": "${label}",
      "score": null,
      "points": [...],
      "group_id": null,
      "description": null,
      "difficult": false,
      "shape_type": "${shape_type}",
      "flags": null,
      "attributes": {}
    }
  ],
  "imagePath": "${filename}",
  "imageData": null,  // base64
  "imageHeight": -1,
  "imageWidth": -1
}

Locate the shape_color field and set its value to "manual" to manually set label colors.
Find the label_colors section, which contains the labels and their corresponding colors.
Locate the label you want to modify, such as "person," "car," "bicycle," etc.
Set the color using RGB values, e.g., [255, 0, 0] for red, [0, 255, 0] for green, and [0, 0, 255] for blue.
Replace the color values for the corresponding label, save the file, and close the editor.

Example configuration:

...
default_shape_color: [0, 255, 0]
shape_color: manual  # null, 'auto', 'manual'
shift_auto_shape_color: 0
label_colors:
  person: [255, 0, 0]
  car: [0, 255, 0]
  bicycle: [0, 0, 255]
  ...
...

After completing these steps, the custom label colors will be applied. The next time you use these labels during annotation, they will display in the colors you set.

In X-AnyLabeling v2.4.0+, label colors can be directly set through the GUI. Navigate to Tools -> Label Manager in the menu bar. Note that these changes are only effective for the current session.

7.3 Loading Predefined Labels

To load predefined labels, you can modify the labels field in the configuration file. When defining label names with pure numbers, be sure to enclose them in single quotes ''. Example:

...
labels:
- car
- '1'
- apple
- _phone

7.4 Auto-Switch to Edit Mode
