> Apple Pencil & gestures
1 BIT PIXEL
1 Bit Pixel is built for touch and Apple Pencil. Here are the gestures and Pencil features — most are optional and live in Settings → Drawing.
Gestures
One finger draws, two fingers pan and pinch-zoom, and (when enabled) a three-finger slide adjusts brush size vertically and opacity horizontally. Two-finger tap to undo isn't needed — undo/redo buttons sit in the toolbar.
Details & edge cases
- The three-finger slide is vertical = brush size, horizontal = opacity, and it's off until you enable it in Settings → Drawing.
- Pencil-only mode rejects finger touches, so you can rest your hand on the screen while you draw.
- Fast strokes keep all their in-between points — the Pencil's high sample rate is fed straight to the brush.
Quick eyedrop & tilt
Turn on Quick eyedrop to long-press anywhere and grab that color without switching tools. Tilt and pressure can drive the brush; you can also map a low-tilt action to a quick tool.
Details & edge cases
- Pressure can drive brush size — it scales within a set range and is capped at 16 px — and tilt can add up to 3 px on top.
- Quick eyedrop's hold time and allowed wobble are configurable, and the pixel you press isn't drawn on.
- Pencil double-tap follows your system setting — switch to eraser or show the palette.
Squeeze, radial menu & scribble
On a Pencil Pro, a squeeze opens a quick menu or a customizable radial menu of your favorite tools. Scribble (off by default, so the Pencil draws) lets you handwrite into text fields like FPS or hex when you switch it on.
Details & edge cases
- The radial menu caps at 8 tools, so it never gets too crowded to tap.
- Squeeze needs a Pencil Pro; on other Pencils, use the on-screen buttons instead.
- Scribble stays off by default so the Pencil always draws — turn it on only when you want to handwrite into fields.
