Shapes
Spark's shape library has over 30 ready-to-go geometric primitives, all drawn with the same click-and-drag workflow.
The Shape Menu Structure
| Submenu | Shapes |
|---|---|
| Basic Shapes | Rectangle, Circle, Triangle, Right Triangle, Semicircle, Diamond, Parallelogram, Trapezoid, Chevron, Bracket Left, Bracket Right, Banner |
| Polygons | Pentagon, Hexagon, Octagon |
| Symbols | Star, Hexagram, Heart, Lightning, Cloud, Cross (plus) |
| Indicators | Checkmark, X Mark, Exclamation |
| Arrows | Single Arrow, Double Arrow, Curved Arrow Right, Curved Arrow Left |
| Callouts | Speech Bubble, Flag |
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
- Pick the shape from Tools → Shapes → … or the toolbar.
- Click and drag on the page to define the bounding box.
- 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
- Activate Freehand (pen icon).
- Hold the left button and drag. Spark records every cursor position.
- Release to finalise.
Freehand strokes are stored as polylines (not bitmaps) so they remain crisp at any zoom.
Drawing a Polyline / Polygon
- Activate the tool.
- Click to add the first vertex.
- Click again to add each subsequent vertex (a "rubber-band" preview follows the cursor).
- Double-click or press
Enterto finish. Escto 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.
