Tool options

Every option in the tool options bar: which tools show it, its values and its default.

The tool options bar above the canvas shows the active tool's options. Change one and it stays that way as you switch tools and back; options that several tools share, like the brush size, are the same for all of them. Options last until you reload the page, unless you save them in a workspace layout (View > Workspace > Save Layout As..., with "Tool defaults" checked).

Where the bar is narrow its options wrap onto more rows, or on a phone scroll sideways. What each tool does with them is in the Tools reference.

With every tool

These sit at the right-hand end of the bar whatever tool is active (Paint across cels only with the painting tools). Each is an on/off button; the small arrow next to it opens its settings.

Option	Values	Default	What it does
Paint across cels	On or off	Off	Paints every cel selected in the timeline at once (the cel you paint on must be one of them): one stroke, fill or shape lands on each, and one undo takes it back. The badge counts the cels it reaches; locked and hidden layers are skipped. With the painting tools.
Symmetry	Horizontal, vertical and the two diagonals, in any combination	None	Mirrors what you draw across the chosen axes. The arrow next to it picks the axes and recenters them; drag an axis on the canvas to move it. Each sprite keeps its own.
Grid	On or off; Snap to grid, Isometric, Grid settings	Off	Shows the sprite's grid. The arrow next to it turns on snapping, switches to an isometric grid and opens the grid settings.
Tiled view	Off, both axes, horizontal, vertical	Off	Repeats the sprite around itself to check that it tiles; each click steps to the next mode.
Onion skinning	On or off, with its settings	Off	Shows the frames before (red) and after (blue) the current one, faded. The arrow next to it holds the onion skin settings.

While a tilemap layer is active, the bar starts with its mode and the tile grid. See Tilemaps.

Option	Values	Default	What it does
Tilemap	Tiles, Pixels: Auto, Pixels: Edit	Pixels: Auto	How tools treat the tilemap layer: Tiles places whole tiles, Pixels: Auto gives each painted cell its own tile, Pixels: Edit changes the tile everywhere it's used. While a tilemap layer is active.
Tile grid	On or off	On	Shows the tile boundaries over the canvas. While a tilemap layer is active.

By tool

Rectangular Selection

Option	Values	Default	What it does
Radius	0 to 1024 px per corner	0 px (square)	Rounds the corners; 0 keeps them square. With the link on, one value sets all four; turn it off to give each corner (top-left, top-right, bottom-right, bottom-left) its own. The Rectangle and the Rectangular Marquee keep separate radii.

Place tiles	On or off	Off	Places the tile picked in the Tileset panel on the tilemap cells the tool covers (the Eraser empties them, the Bucket fills the connected cells holding the clicked tile) instead of painting pixels. Symmetry mirrors the tiles and a selection limits them. While a tilemap layer is active.
Paint across cels	On or off	Off	Paints every cel selected in the timeline at once (the cel you paint on must be one of them): one stroke, fill or shape lands on each, and one undo takes it back. The badge counts the cels it reaches; locked and hidden layers are skipped. With the painting tools.

With the Shading ink.
Dynamics	Pencil Eraser Dither	Stabilizer; pressure and speed mapped to size, angle and gradient	Pressure to size (pen only)	Smooths the stroke (Stabilizer) and lets pen pressure or speed vary the size, the angle, or the color from foreground to background. Pressure only comes from a pen: mouse and finger strokes ignore it.
Fill	Rectangle Ellipse Triangle Hexagon Star Polygon Curve	Outline, Filled	Outline	Draws the shape's outline, or fills it. A curve only fills when it's closed.
Radius	Rectangle Rectangular Selection	0 to 1024 px per corner	0 px (square)	Rounds the corners; 0 keeps them square. With the link on, one value sets all four; turn it off to give each corner (top-left, top-right, bottom-right, bottom-left) its own. The Rectangle and the Rectangular Marquee keep separate radii.

Strength	Dodge/Burn	1 to 100	25	How much each stroke lightens (or, with the right button, darkens) the pixels it touches, in perceptual lightness. 100 moves half way from black to white.
Hue shift	Dodge/Burn	0° to 60°	0°	Also turns the hue of each pixel it touches: lightening shifts toward warm yellow and softens the color, darkening (right button) shifts toward cool blue and deepens it, the way pixel artists shade. 0 keeps the hue.
Pattern	Dither	Bayer 2×2, Bayer 4×4, Bayer 8×8, Dots, Horizontal lines, Vertical lines, Diagonal lines, Noise	Bayer 2×2	The pattern the brush paints through: Bayer checkers (2×2 coarsest, 8×8 finest), halftone dots, lines, or an even noise scatter. It lines up with the sprite's top-left corner, so strokes that overlap stay on one pattern.
Density	Dither	0% to 100%	50%	How much of the pattern gets painted: 50% of Bayer 2×2 is a checkerboard, 100% paints every pixel.
Type	Gradient	Linear, Radial	Linear	A straight ramp along the drag, or rings around its start.
Colors	Gradient	FG → BG, Stops	FG → BG	Run from the foreground to the background color, or through the Stops.
Stops	Gradient	Up to 32 colors, each at a position along the drag	Empty	The colors the gradient runs through, left = where you start dragging: click the bar to add the foreground color, drag a handle to move its stop (meeting a neighbour makes a hard edge) or off the bar to remove it, drop palette colors on the bar or a handle; Even spreads them out, FG recolors the selected stop.

Dither	Gradient	None, Bayer 2×2, Bayer 4×4, Bayer 8×8, Dots, Horizontal lines, Vertical lines, Diagonal lines, Noise	Bayer 4×4	None blends smoothly; the others step between the colors in a pattern, for a pixel-art look: Bayer checkers (2×2 coarsest, 8×8 finest), halftone dots, lines, or an even noise scatter.
Snap	Gradient	Free, Palette	Free	Free blends any colors; Palette paints only palette colors, each pixel the nearest one, and with Dither steps between neighbouring palette colors.
Rotation algorithm	Move	Fast Rotation, RotSprite, Bilinear	RotSprite	How rotated and scaled pixels are resampled: Fast Rotation keeps them sharp, RotSprite rotates pixel art cleanly, Bilinear blends them smoothly.
Pivot	Move	A corner, an edge's middle, or the center	Center	Where the point everything turns and scales around starts; you can also drag it on the canvas.

Stop at grid	Magic Wand	On or off	Off	Keeps the selection inside the grid cell you click. While the grid is shown.
Fill mode	Paint Bucket Gradient	Contiguous, Global	Contiguous	Only the connected area you click, or every matching pixel on the layer.
Tolerance	Paint Bucket Gradient	0 to 255	0	How different a color can be and still match (per color channel).
8-connected	Paint Bucket Gradient	On or off	Off	Also spreads to diagonal neighbours, so the area leaks through 1 px diagonal lines. Off, only up, down, left and right count as connected. With Contiguous.
Stop at grid	Paint Bucket Gradient	On or off	Off	Keeps the area inside the grid cell you click. While the grid is shown.
Close gap	Paint Bucket Gradient	0 px to 5 px	0 px	Treats gaps in an outline up to this many pixels wide as closed, so the fill stops there instead of leaking out (the gap itself is filled). 0 is off. With Contiguous.
Pattern	Paint Bucket	Solid, Checker, Dither 25%, Dither 75%, Horizontal stripes, Vertical stripes, Diagonal, Grid, Dots, Bricks	Solid	Fills with a repeating pattern of the foreground and background colors (swapped on right-click) instead of a solid color.
