Fill & Eyedropper
Fill (bucket)#
The Fill tool floods an area with the foreground colour. Tap inside the region you want to fill.
Options (context bar)#
| Option | Effect |
|---|---|
| Contiguous / Global | Contiguous fills only the connected region you tapped. Global replaces every matching pixel on the layer. |
| Tolerance | How different a neighbouring pixel's colour can be and still be filled. 0 fills only exact matches; higher values bleed into anti-aliased or noisy edges. |
| Fill in selection / Fill everywhere | Restrict the flood to the active selection, or ignore it. |
| Ignore foreground | When on, the tool treats pixels that already match the foreground colour as fillable — useful for re-flooding an area. |
The fill also honours the current dithering pattern (see Gradient & dithering) and, on an indexed sprite, snaps to the palette.
On a very large canvas the fill commits on touch-up, so a stray two-finger undo tap during the same gesture won't leave a half-fill behind.
Eyedropper#
The Eyedropper samples a colour from the canvas and makes it the foreground.
- **Tap*a pixel to pick its colour.
- **Long-press*anywhere (default long-press action) to sample without switching tools — the loupe appears so you can place the sample precisely.
Sample source (tool rail)#
| Source | Samples from |
|---|---|
| Layer | Only the active layer. |
| All Layers | The composited image — what you see. On transparent areas it will pick up a visible reference image. |
| Reference | The active reference image only. |
If the sampled colour already exists in the palette, that swatch is selected rather than a duplicate being added. Picked colours are added to Recent colours but do not grow the palette.
