A single generation step.

A single generation step containing quadrants to generate together.

A position in the quadrant grid.

Builds template images for infill generation. Handles: - Optimal placement of infill region to maximize context - Validation of edge constra

A single step in the generation plan.

A complete generation plan for a rectangle.

Manages the state of quadrants in a tile generation grid. The grid tracks which quadrants are: - GENERATED: Already have pixel art generation

A bounding box in pixel coordinates.

A single item in the generation plan.

Bounding box defined by top-left and bottom-right corners.

In-memory grid of quadrant states. This class manages the state of all quadrants within a bounding box and helps construct generation plans.

Describes where to place the infill region within the template. The template is always 1024x1024. This specifies: - Where the infill region sh

A single item from the generation plan.

Per-image settings from CSV or defaults.

Handles positioning and validation of arbitrary rectangular infill regions. Rules: 1. Infill area must be ≤ 50% of template area 2. If infil

A complete generation plan with metadata.

Describes the context (generated pixels) available around an infill region. Each boolean indicates whether there are generated pixels in that di

A rectangular region to be infilled. Coordinates are in "world" pixel space, where: - (0, 0) is the top-left of quadrant (0, 0) - x increase
