Export an existing image set as icons, free: every subject at the base size you name and at every density the web, iOS, Android and Flutter need, laid out as each expects (web files with @2x and @3x and an srcset line, an iOS asset catalog with one imageset per icon, Android res/ density buckets, Flutter asset folders with the pubspec lines), plus a viewer and a ledger. One export per call: one batch of a set (a set that grew over several calls is exported batch by batch; the trees merge by folder) at one base size (a second size is a second call; names carry the size, so two sizes never collide). The icons come from the set's full-resolution source, so an icon is the set as it is currently delivered, scaled: its size, canvas, sizing and margin all carry (edit_image_set changes them), while no pixel comes from a delivered image. Files up to 3x the 1x size (4x on Android) are always delivered; where a density would enlarge a subject past its source pixels the ledger says so per tree ("soft": some blur) and by how much, never withholding a file. Large base sizes cost real megabytes for files the ledger will mark soft; 48 to 128 is the usual range. How large a set's icons can be was fixed when it was generated, by its subject count: every generation result and list_recent_generations state the batch's crisp base size, and the ledger says where a larger size went past the source. Not available for illustrations, or for sets generated before editing existed (they have no source).
