This layer (duplicate_objects) clones figures of required classes.

{
  "dst": "$sample2",
  "src": [
    "$sample1"
  ],
  "action": "duplicate_objects",
  "settings": {
    "classes_mapping": {
      "bitmap-one": "bitmap-two"
    }
  }
}

For the settings above, each figure of class "bitmap-one" will be cloned with class "bitmap-two", leaving the source figure unchanged. This will not create new sample (new image), so both source and resulting figures will belong to the same image.

Settings

• classes_mapping — dict where keys are existing classes, and values are new names of classes.
