Basic Shapes

Moon

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

Search words: crescent, night

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

NameDefaultRange
adj0.50 to 0.875

OPF units: fractions (most often of the shorter side) and degrees, for example "adjust": { "adj": 0.5 }.
