Pixel-Perfect, Auto-fill, and symmetry

Pixel-Perfect

Section titled “Pixel-Perfect”

When drawing a one-pixel diagonal, an extra corner pixel can make the contour look heavier than its neighbors. Enable Pixel-Perfect to remove that corner as you draw, then inspect the silhouette at its intended display size.

Pixel-Perfect is an independent Pencil, Eraser and Vector Pencil option at 1 px. It removes the middle pixel from an L-shaped corner as you draw. Changing that tool’s size above 1 px turns its Pixel-Perfect option off. Vector Pencil stores the setting with each editable freehand path.

It does not smooth or blur the artwork.

Auto-fill

Section titled “Auto-fill”

Enable Auto-fill for Pencil to fill regions newly enclosed when you release a stroke. You can draw a whole closed contour in one gesture, or close a gap in an older raster contour on the current layer.

For example:

  1. Draw three sides of a box on a Pixels layer.
  2. Enable Auto-fill.
  3. Draw the missing side so it meets both ends of the earlier contour.
  4. Release the mouse to fill the newly enclosed region.

The earlier contour and new stroke must actually enclose pixels. Auto-fill is not the same as clicking an existing closed area with Fill. It is not applied while erasing or using Pencil Shading ink.

Symmetry

Section titled “Symmetry”

Mirror your strokes to draw both halves of a front-facing character, shield or ornament together. Turn symmetry off to add asymmetrical details.

The Symmetry group is directly visible in the Pencil and Eraser context bars.

  • Horizontal mirrors left and right across a vertical guide.
  • Vertical mirrors top and bottom across a horizontal guide.
  • Enable both for four-way drawing.
  • Use the target-shaped reset button to return the axes to the document center.

Drag a canvas-edge handle to move an enabled axis. Axis positions snap in half-pixel steps. Moving or resetting an axis does not paint or create a document history edit.

Symmetry works with Pixel-Perfect and Auto-fill. Selection limits and layer clipping still apply to the mirrored pixels. Each stroke stays one undoable edit.
