Import images
Basics
Ansel backbone is a library of images, saved as an SQLite database into ~/.config/ansel/library.db. Since Ansel is a non-destructive photo editor, editings are saved as histories of settings, along with image metadata, as text1 into the library database. The application of editing histories over raw images, as to produce output raster images, is the export step.
The library is also used to keep track of image collections (by tags, folders, EXIF, editing time, etc.). Because of this, we need to make the library aware of new images : it is the import step. This will initialize a new database entry with metadata and a virgin history for each imported picture.
