Database API¶

ClickPoints comes with a powerful API which enables access from within python to ClickPoints Projects which are stored in a .cdb ClickPoints SQLite database.

To get started reading and writing to a database use:

import clickpoints
db = clickpoints.DataFile("project.cdb")

This will open an existing project file called project.cdb.

Note

The Examples section demonstrates the use of the API with various examples and provides a good starting point to write custom evaluations.

Database Models¶

The .cdb file consists of multiple SQL tables in which it stores its information. Each table is represented in the API as a peewee model. Users which are not familiar can use the API without any knowledge of peewee, as the API provides all functions necessary to access the data. For each table a get (retrieve entries), set (add and change entries) and delete (remove entries) function is provided. Functions with a plural name always work on multiple entries at once and all arguments can be provided as single values or arrays if multiple entries should be affected.

The tables are: Meta, Path, Layer, Image, Offset, Track, MarkerType, Marker, Line, Rectangle, Mask, MaskType, Annotation, Tag, TagAssociation.
