You can use the Pencil tool to draw 1-pixel lines, either freehand lines or constrained, straight lines, much as you use a real pencil, with or without a ruler, to draw hard-edged lines. You can also zoom in on a bitmap and use the Pencil tool to edit individual pixels.

To draw an object with the Pencil tool:

  1. This is a picture of the feature being described.Select the Pencil tool.
  2. Set tool options in the Property inspector:

    Anti-aliased smooths the edges of the lines you draw.

    Auto Erase uses the fill color when the Pencil tool is clicked over the stroke color.

    Preserve Transparency restricts the Pencil tool to drawing only in existing pixels, not in transparent areas of a graphic.

  3. Drag to draw. Shift-drag to constrain the path to a horizontal, vertical, or diagonal line.
