Network activity

Tools exposed (18)

• preflight

  Check that Aseprite is connected and report what this session can do. Call this FIRST in any pixel-art task and stop if `ready` is false — every editing tool writes into the user's open Aseprite window ('live') or into a batch Aseprite this server owns ('headless'), and there is no useful fallback w

• sprite_info

  Full structured state of a sprite: dimensions, colour mode, palette, every layer (with opacity, blend mode, visibility, group nesting), every frame with its duration, animation tags, slices and the current selection. Read this before editing — guessing at layer names or frame counts is the most comm

• sprite_manage

  Open, create, focus, resize, save and close sprites in the running Aseprite session. Ops: 'list' (open documents), 'new', 'open', 'activate', 'save', 'save_as', 'close', 'resize_canvas', 'set_properties', 'slice_create', 'slice_update', 'slice_delete'. Canvas resize keeps existing pixels — pass an a

• look

  See what is actually on the canvas. Ops: • 'preview' — a nearest-neighbour upscaled PNG of the active frame (~1024px long edge). Use for overall read: silhouette, colour, whether it looks like the thing. • 'ascii' — an exact text grid, one glyph per pixel with a colour legend and coordinate rulers.

• read_pixels

  Read a rectangular region as structured data: a list of distinct colours plus a row-major index grid. Use this when you need to compute over pixels (sample a palette from art, find a silhouette edge, copy a region) rather than just look at them. For eyeballing, 'look' is cheaper.

• draw

  Apply a batch of drawing operations to one cel, as a single undoable action. Ops: pixels, line, polyline, rect, ellipse, fill, replace, dither, gradient, clear, blit, text, grid. Batch aggressively — a whole sprite in one call is normal and correct, and it means the user can undo your work with one

• select

  Read or change the active selection. Ops: 'get', 'none', 'all', 'rect', 'ellipse', 'color' (select every pixel matching a colour), 'invert', 'grow', 'shrink'. A selection scopes draw, transform and recolor, which is usually cheaper and safer than masking by hand.

• transform

  Move, flip, rotate or scale pixels on ONE cel — the target layer's image on the target frame. Ops: 'translate', 'flip', 'rotate', 'scale', 'outline', 'crop_to_content'. To transform part of a cel, crop the region out with `draw` op 'blit' first; there is no selection-scoped transform. Rotation is on

• layer

  Manage layers. Ops: 'list', 'create', 'rename', 'delete', 'reorder', 'set' (visibility/opacity/blend/lock), 'group', 'ungroup', 'merge', 'duplicate', 'activate'. Pass `batch` to run several in one undoable action — building a rig in one call is the normal use. 'duplicate' takes an optional `toSprite

• frame

  Manage animation frames. Ops: 'list', 'add', 'duplicate', 'delete', 'set_duration', 'activate', 'reorder'. Durations are milliseconds per frame and carry most of the life in a cycle — hold a contact pose longer than a pass pose. Use `count` to add several at once and `durations` to set a whole cycle

• tag

  Manage animation tags — the named frame ranges a game engine imports as 'idle', 'walk', 'attack'. Ops: 'list', 'create', 'update', 'delete'. Tag every cycle before export; an untagged spritesheet is a pile of frames the engine cannot address.

• cel

  Manage cels — one layer's image on one frame. Ops: 'list', 'create', 'clear', 'delete', 'move', 'copy', 'link', 'unlink', 'set' (position/opacity), 'tween', 'oscillate'. 'move' is how you shift a whole limb between frames without redrawing it; 'link' shares one image across frames so a static part o

• palette

  Read and shape the sprite's palette. Ops: • 'get' — current palette with per-colour usage counts. • 'set' — write specific indices, or replace the palette wholesale. • 'preset' — load a bundled palette by key: ~2000 of them, the classics (pico8, gameboy, cga, nes…) and the most-downloaded on Lospec

• recolor

  Change colours in a region by intent, staying palette-legal. Ops: • 'shade' — darken or lighten with proper hue shifting (shadows cool, highlights warm). Use this instead of picking a darker hex by hand. • 'snap' — pull off-palette pixels onto the nearest palette colour by perceptual (CIELAB) distan

• validate

  Lint a sprite against pixel-art rules and report concrete, located problems. Checks: off-palette colours, orphan/stray pixels, broken or doubled outlines, banding, semi-transparent (soft or resized) pixels, empty layers, untagged frames and uniform frame timing; `expect` adds per-layer frame ranges

• reference

  Bring an external image into the sprite as a reference layer, so you can trace proportions or sample colours from it. Ops: 'import' (place an image on a locked, semi-transparent layer above the art), 'sample_palette' (read its dominant colours without importing), 'list', 'remove'. A concept sheet or

• export

  Write game-ready files. Ops: 'png' (single frame), 'gif' (animation), 'spritesheet' (packed sheet plus a JSON atlas with per-frame and per-tag data), 'frames' (numbered PNGs), 'aseprite' (save a copy of the source). Spritesheet is what an engine actually consumes: pass `sheetType` and `byTag` to con

• tileset

  Work with Aseprite tilemap layers. Ops: • 'list' — tilesets in the sprite. • 'create_layer' — a new empty tilemap layer on a given grid. • 'get' — tile count and, with a path, the tiles as one packed PNG. • 'stamp' — place tiles by grid coordinate. x/y are grid cells, not pixels. • 'pack' — turn a h
