Basic packing of two rectangles into a 100x100 bin using MaxRects BSSF algorithm.

from rectpack import Packer, MaxRectsBssf from rectpack import SORT_AREA packer = Packer() # Use a packing algorithm packer.add_bin(100, 100) packer.add_rect(50, 30, rid='rect1') packer.add_rect(20, 40, rid='rect2') packer.pack_algo = MaxRectsBssf() packer.sort_algo = SORT_AREA packer.pack() for rect in packer.rect_list(): print('Rectangle:', rect) # Alternatively, get a summary print('Bins:', packer.bins) # list of Bin objects print('Unpacked:', packer.unused_areas())

Debug

Known issues

gotchaThe library does not check if a rectangle fits before packing. If no bin can accommodate, the rectangle is silently left unpacked. Always check packer.rect_list() against your input.

fix

After packing, iterate packer.rect_list() and compare with input counts to detect unplaced rectangles.

affects: all

deprecatedThe attribute 'pack_algo' is being replaced by 'pack_algo' usage as a property. In older examples, they assigned the algorithm class directly; now use an instance.

fix

Use: packer.pack_algo = MaxRectsBssf() (with parentheses)

affects: <0.2.0

gotchaRectangles added without 'rid' will be assigned a default id (e.g., 'rect_0'). If multiple rectangles have the same rid, later ones overwrite earlier ones in internal dictionary. Use unique rid per rectangle to avoid data loss.

fix

Always provide unique rid strings, e.g., f'rect_{i}'.
