        "description": "# Package *bbx*\n\nSimple operations over bounding boxes.\n_Bounding boxes_ are represented in XYWH format where `(X,Y)` is coordinate of top-left corner, and `(W,H)` its size. I.e. `bb = [0,0,64,16]` represents a rectangle of size 64x16 located at coordinate `(0,0)`. The units are always abstract - the interpretation is left for the user (usually _pixels_ are used).\n\nThe package defines several common operations - resize, aspect ratio changes, randomization.\n\n```python\nimport bbx\n\nbb = (-5,-5,10,10)   # Center at (0,0)\nbb = bbx.set_aspect_ratio(bb, 2, bbx.KEEP_WIDTH)\nprint(bb)  # Prints [[-5.0, -10.0, 10, 20]]\n```\n\n# Installation\n\nThe package is in PyPI so just use `pip`\n```\npip install bbx\n```\n\n# Documentation\n\nBounding boxes are defined in x,y,w,h format, but they can hold any additional information (e.g. ignore flag). All functions always work on first four elements.\n\n## `bbx.set_aspect_ratio(bbs, ar, type)`\nSet aspecr ratio `ar` to all bounding boxes in `bbs` using `type` method. The `type` can be one of:\n* `bbx.EXPAND`\n* `bbx.SHRINK`\n* `bbx.KEEP_WIDTH`\n* `bbx.KEEP_HEIGHT`\n* `bbx.KEEP_AREA`\n\nFor unknown type, the function raises `NotImplementedError`\n\n\n## `bbx.resize(bbs, scale)`\nResize `bbs` by `ratio` without moving center. The `ratio` can be:\n* scalar - all boxes are resized by the same factor\n* tuple of two scalars - resize all boxes with different scale for width and height\n\n## `bbx.scale`\n\n## `bbx.move`\n\n## `bbx.center`\n\n## `bbx.overlap`\n\n## `bbx.dist_matrix`\n\n## `bbx.nms`\n\n## `bbx.groups`\n\n## `bbx.randomize`\n\n\n# TODOs\n* Documentation\n* Tests\n\n# License\n\nThis code is published under [MIT License](LICENSE)",
