minieye-image-overlay

Shared PIL/numpy post-processing helpers for text, legends, and tile labels on already-rendered PNG images.

The package intentionally depends only on numpy and Pillow. OpenCV callers can use the BGR entrypoint without adding an OpenCV dependency to this package.

build_four_view_overlay_spec() supports lower-right panels with mode="field_range" and mode="key_values". A key/value panel accepts an optional title plus ordered {"label": ..., "value": ...} items:

right_panel = {
    "mode": "key_values",
    "title": "lidar -> ins extrinsic",
    "items": [
        {"label": "translation xyz (m)", "value": "[-2.77, 0.00, -1.95]"},
        {"label": "quaternion xyzw", "value": "[-0.007, -0.002, 0.003, 0.999]"},
    ],
}
