Shapes

Spark's shape library has over 30 ready-to-go geometric primitives, all drawn with the same click-and-drag workflow.

Plus the drawing-oriented tools:

  • Freehand — pen-style drawing (every cursor point is recorded).
  • Polyline — connected line segments; click to add, double-click to finalise.
  • Polygon — closed polyline; click to add, double-click to finalise.
  • Eraser — erase parts of freehand / polyline.
  • Revision Cloud — free-form cloud (see 03.7).

Drawing a Predefined Shape

  1. Pick the shape from Tools → Shapes → … or the toolbar.
  2. Click and drag on the page to define the bounding box.
  3. Release. The shape's geometry is auto-generated inside that box.

The shape is drawn stroke-only by default. Fill is optional (set in Tool Options before drawing).

Drawing Freehand

  1. Activate Freehand (pen icon).
  2. Hold the left button and drag. Spark records every cursor position.
  3. Release to finalise.

Freehand strokes are stored as polylines (not bitmaps) so they remain crisp at any zoom.

Drawing a Polyline / Polygon

  1. Activate the tool.
  2. Click to add the first vertex.
  3. Click again to add each subsequent vertex (a "rubber-band" preview follows the cursor).
  4. Double-click or press Enter to finish.
  5. Esc to cancel without creating.

Polygon closes the path back to the first vertex. Polyline stays open.

Line Styles

In Tool Options:

  • Solid (default)
  • Dashed– – – –
  • Dotted· · · ·
  • Cloud — scalloped (see 03.7)
Tip

Tip — Cloud line style works on Rectangle and Circle too: draw a rectangle with cloud line-style and you get a rectangular revision cloud.

Fill, Stroke and Opacity

  • Stroke color — pick in Tool Options.
  • Fill color — separate; default transparent.
  • Stroke thickness — 0.5 to 10+ pt.
  • Opacity — applies to both stroke and fill.

After Drawing

Select the shape and you get the 8-direction resize box, rotation handle, and (for polygon / freehand / polyline) per-vertex orange handles. See 04.3 for vertex editing.
