sprite_sheet_slice — GFX2D `sprite` op

• Data kinds: rgba → sprites

• Call: import gfx2d; gfx2d.sprite_sheet_slice(sheet, tile_height, tile_width, margin=0, spacing=0, count=None) (or opsgfx2d.get("sprite_sheet_slice"))

Usage

Cut a sprite atlas into a list of equal `rgba` frames, row-major.

`margin is the border around the whole sheet, spacing` the gap between

neighbouring cells — the two numbers that every atlas exporter writes and

that every hand-rolled slicer gets wrong by one.

Returns a `list of (tile_height, tile_width, 4)` arrays. With

`margin=spacing=0 it is the exact inverse of :func:tilemap_render`.

Raises ValueError: a sheet that does not contain a whole number of cells

(a partial cell means the margin/spacing are wrong, and silently dropping it

hides that), a `count` larger than the grid, more than

:data:MAX_SPRITES cells.
