Fill and Eyedropper

Solid Fill

Block in a closed silhouette without painting its interior stroke by stroke. Use a selection when the color should affect only part of a larger region.

Press G and choose solid Fill in the context bar.
Choose the drawing color and set opacity.
Click inside the region with the left button to use foreground, or the right button to use background.

Fill options

Tolerance controls how different a pixel may be from the clicked color (0–255). Zero matches exactly; transparent pixels match regardless of their hidden RGB.
Contiguous limits filling to the connected region. Turn it off to fill all matching pixels across the canvas.
Include diagonals connects diagonal neighbors when Contiguous is on.
Visible layers uses the visible composite as the reference. Turn it off to reference the active layer. Filling still writes to the target layer.

Fills respect the active selection and layer protection. Each completed fill is one undoable edit. For two-color fills, see linear gradient.

Fill editable outlines

Live fills follow changes to an editable silhouette, so you can reshape its boundary without repainting the interior.

Closed regions enclosed by several editable paths can be filled before rasterization. Live fills follow their editable boundaries. If a boundary opens or the region becomes ambiguous, the fill becomes unresolved instead of spreading across the canvas. Repair the boundary to restore the region. Use visible-layer reference when the outlines are on another visible layer.

Fill a mixed outline

An open editable curve and Pencil strokes can close a region together. Enable Visible layers if the boundary is spread across layers, then fill the region. The paths remain editable, but the fill is raster paint. It keeps the shape it had when you clicked. Later boundary edits do not reshape it; undo or refill to change the result.

A region already enclosed by paths alone keeps the linked-fill behavior above. Selections use ordinary raster Fill. Open contours can leak, depending on tolerance and connectivity. Hidden layers are excluded from visible sampling; visible locked layers can serve as boundaries, but the target must be unlocked.

Eyedropper

Select Eyedropper (I), then click or drag over the image. Left samples foreground; right samples background. Sampling uses one pixel of the visible composite, including layer opacity and offsets. Transparency is included; the checkerboard and canvas surround are never sampled. Hold Alt with Pencil or Eraser to sample temporarily, using the same left/right destinations, then release Alt to continue drawing.

Sampling changes the drawing colors without changing artwork or adding undo history. Press B to return to Pencil.

You can also click the eyedropper in the Color panel to sample into the foreground color without switching tools. In a full Color Chooser, its eyedropper samples only into the color being edited, including palette or gradient colors. Its swatch previews the pixel under the pointer without changing the field. Left-click a canvas pixel or release a left-drag to confirm, including transparency. Right-click or press Escape to cancel sampling without closing the chooser. Releasing outside the image cancels without changing the color.

With Pencil in Paint mode, a fully transparent foreground or background color erases using the corresponding mouse button. This keeps your Pencil tip, size and opacity. Hold E for the separate temporary eraser when you want to keep your drawing colors. See Pencil and Eraser.

Replace a color

Replace a color in a painted sprite or across selected animation cels. This changes the artwork’s pixels; editing a palette swatch only changes the palette.

Choose Filter > Replace Color… on a visible, unlocked raster layer. Use the source and replacement color buttons to open the same color controls used elsewhere in Pixelithra. Set Tolerance to 0 for an exact RGBA match or raise it to include similar component values. Fully transparent pixels are included only when the source color is transparent.

The canvas previews the result. An existing raster selection clips each target cel at document coordinates, including offset layers. Choose Apply for one undoable edit or Cancel to preserve the original. Editable paths and live-fill content are excluded rather than rasterized implicitly.

Enable Selected frames and layers to apply the operation to each selected layer in every selected Animation frame. Every target must be an editable raster cel; an invalid target rejects the whole operation.

Remap artwork to a palette

Load the colors you want into the document palette, then choose Filter > Palette Remap…. The filter works on the active visible, unlocked Pixels layer in the current frame. If you have a selection, it works only inside the selection.

With Dithering set to Off, each painted pixel takes the RGB values of the closest nontransparent swatch. If two swatches are equally close, the first in the palette wins. Every mode preserves pixel opacity and leaves fully transparent pixels untouched.

Dithering starts at Off each time you open the filter. Choose Bayer 2×2, Bayer 4×4 or Bayer 8×8 to suggest intermediate tones with a repeating pattern of palette colors. The pattern stays aligned to the canvas when the layer is offset or a selection clips the effect. Pixels that already match a swatch keep their color.

Use Preview on canvas to compare the result with the original. Apply commits one undoable edit. Cancel closes the preview. If the artwork already matches the palette, there is nothing to apply.

Recolor by brightness

Choose Filter > Gradient Map… on the active visible, unlocked Pixels layer. Click at least two distinct, nontransparent colors in the document palette. The order you pick them defines the ramp from shadows to highlights. Select a ramp color and use the arrows to move it, or choose Remove to take it out of the ramp.

Each painted pixel takes the ramp color closest to its brightness. The colors are evenly spaced and keep their exact RGB values, giving you discrete tone bands. The filter keeps pixel opacity and leaves fully transparent pixels alone. It works on the current frame, inside the selection if you have one.

Toggle Preview on canvas to compare the result with the original. Apply commits one undoable edit. The document palette keeps its colors and order.
