Basic Shapes

Pentagon

"shape": "pentagon" draws PowerPoint's pentagon preset. The PPTX export writes it as a native shape with its adjust values, so it stays editable in PowerPoint.

Search words: five, sides, regular, polygon

Frame

A shape block takes the largest frame of 1:1 (width to height) that fits its cell, centered; set aspectRatio for another. Text inside is fitted to the preset's text rectangle and never set below the readability floor.

Adjust Values

Name	Default	Range
hf	1.05146	unbounded to unbounded
vf	1.10557	unbounded to unbounded

OPF units: fractions (most often of the shorter side) and degrees, for example "adjust": { "hf": 1.05146 }.
