# `Etcher.Annotation`
[🔗](https://github.com/alexdont/etcher/blob/v0.1.0/lib/etcher/annotation.ex#L1)

Ecto schema for the bundled `etcher_annotations` table.

Used by `Etcher.Storage.Default`. Consumers who implement their own
`Etcher.Storage` adapter against a custom table can ignore this
schema entirely.

## Fields

  * `:uuid` — UUIDv7 primary key
  * `:target_type` — string identifying the kind of resource the
    annotation is on (e.g. `"file"`, `"document"`, `"product"`)

  * `:creator_uuid` — UUID of the user who drew it (nullable)
  * `:kind` — `"rectangle"` | `"circle"` | `"polygon"` | `"freehand"`
  * `:geometry` — JSONB; shape-specific coordinates in image pixels
      * rectangle: `%{"x" => x, "y" => y, "w" => w, "h" => h}`
      * circle: `%{"cx" => cx, "cy" => cy, "r" => r}`
      * polygon: `%{"points" => [[x1, y1], [x2, y2], ...]}`
      * freehand: `%{"points" => [[x1, y1], [x2, y2], ...]}`
  * `:style` — JSONB; optional stroke color / line width
