Fills and gradients
Paint bucket
The bucket (G) fills the area of the same color under the pointer. In its options:
- Contiguous area only (on by default): only the pixels that touch. Off, it replaces that color everywhere on the layer.
- In a selection, it fills the whole selection.
Lasso fill
The lasso fill (K) draws a shape freehand and fills it with the color when you let go. Right-click fills with the color behind. It’s the quickest way to block in a shape before the details.
Gradient
The gradient (D) shares a button with the bucket. Drag from where it starts to where it ends (Shift: by 45°). It fills the area of the same color under the first click, or the selection.
- Shape: linear, radial, angular or diamond.
- Stops: the bar in its options shows the colors. Click it to add a stop, drag a stop to move it, click a stop to change its color: any color, with the same square, hue and opacity as your colors’ picker, or one of the palette’s, or transparent. It starts from your two colors.
- Dithering: between two colors, pixels alternate in a pattern instead of a new color: smooth (an ordered pattern, the classic Bayer), checker, or bands with no dithering at all.
- The gradient only uses its stops’ colors: pick them from the palette, and it stays within it.
- Change the options right after drawing: the last gradient follows them.
