Presets & Atlas

Two small preset libraries — Brush presets and the Stamp library — plus the Atlas browser, which turns an imported sprite sheet into a searchable grid of ready-to-stamp sprites.

← Interface overview

Brush presets

Snapshots of a tool's full settings — size, shape, color, alpha — one click to reapply. Every brush-capable tool can be saved except Stamp, which has its own library below.

1
＋ Save

Captures the active tool's full settings (size, shape, spacing, strength, color, alpha) as a new preset.

2
↑ / ↓ Export / Import

Save the whole library to a JSON file, or load one back in — for sharing a brush set between projects or machines.

3
Preset chip

Icon = the tool it belongs to; the number badge is that preset's brush size. Click applies it (switches tool + restores every saved setting).

Stamp library

Saved pixel blocks instead of settings — crop a selection or the whole canvas, then reuse it as a stamp anywhere, in any project.

1
＋ Save

Bakes the active pixel selection (or, with none, the whole canvas) into a stamp, cropped to its opaque bounds.

2
↑ / ↓ Export / Import

Same JSON round-trip as Brush presets, kept as a separate file/library.

3
Stamp chip

Click selects it as the current stamp brush. Drag it straight onto the canvas to place a copy without switching tools first. Pixels past the canvas edge stay on the layer (overflow); a tiled axis wraps instead.

Atlas browser

Import a sprite sheet (TexturePacker, Aseprite, LibGDX/Spine, Unity, Godot, a Pixis sheet, or a plain uniform grid) and every sprite becomes a searchable, stampable tile.

1
↓ Import atlas

Opens File → Sprite atlas… — pick the sheet image (+ its JSON/.atlas/.plist/.tres metadata where the format needs one).

2
✕ Remove atlas

Drops the active atlas from this session (import is session-only — nothing is written to the project).

3
⭐ Add to stamp library

Promotes the selected sprite into the Stamp library above, so it survives after the atlas is removed.

4
BG

Strips a flat background color from each sprite on import (useful for sheets exported without alpha).

5
Atlas select / Filter / Grid

Switch between several imported atlases; filter sprites by name, tag or #rrggbb; Grid W/H/margin/spacing is only used for a plain image with no metadata (uniform-grid import).

6
Sprite grid

Click a tile to activate it as the current stamp brush (equivalent to selecting Stamp + that pixel block) — pixels are extracted lazily, on first view.

Gestures & shortcuts

Any preset chip (brush or stamp)
  • Click — apply / activate
  • Drag — reorder within its library
  • Hold (~500ms) — remove
  • Right-click — assign a hotkey to that specific preset
Stamp chip only
  • Drag onto the canvas — places a copy there directly (not clipped at the canvas edge), restoring the previous tool afterward
Atlas sprite tile
  • Click — activate as the current stamp brush
  • Drag onto the canvas — same one-shot place as a stamp chip (overflow past the edge; tiled axes wrap)
  • ⭐ toolbar button — copy it into the permanent Stamp library
Scope
  • Brush/Stamp libraries persist locally and travel with Export/Import.
  • Atlas imports are session-only — reload the page and they're gone (promote anything worth keeping to the Stamp library first).
