Internally, paths are stored as a list of sub-paths (lines, arcs, etc.) which together form a shape. The first step to create a path is to call the beginPath(). fill()ĭraws a solid shape by filling the path's content area. stroke()ĭraws the shape by stroking its outline. closePath()Īdds a straight line to the path, going to the start of the current sub-path. Methods to set different paths for objects. Once created, future drawing commands are directed into the path and used to build the path up. Here are the functions used to perform these steps: beginPath()Ĭreates a new path. Once the path has been created, you can stroke or fill the path to render it.Then you use drawing commands to draw into the path.To make shapes using paths, we take some extra steps: A path, or even a subpath, can be closed. A path is a list of points, connected by segments of lines that can be of different shapes, curved or not, of different width and of different color. If you want to delete multiple shapes, select the first shape, press and hold Ctrl while you select the other shapes, and then press Delete.Now let's look at paths. To open Edit Points mode with keyboard shortcuts, select the shape and then press Alt + JD, E, E.Ĭlick the shape that you want to delete, and then press Delete. To cancel the change to the point and line segments, press Esc before releasing the mouse button. After fiddling with coordinates as suggested arrived at this interesting result (iOS simulator): Notice only upper left corner is missing pixels for some rectangles.

A corner point joins two line segments with one segment going off in a different direction. Can't post code since it depends a lot on the underlying framework, but all draw calls are nothing more than glDrawElements with index buffer pointing to 4 vertices, no alpha tests. Once you stop dragging the point will be changed to a corner point. To have the point treated as a corner point, press Alt while dragging either of the handles attached to the point. A straight point joins two line segments of different lengths. Once you stop dragging the point will be changed to a straight point. To have the point treated as a straight point, press Ctrl while dragging either of the handles attached to the point. A smooth point joins two line segments of equal length. Once you stop dragging, the point will be changed to a smooth point. To have the point treated as a smooth point, press Shift while dragging either of the handles attached to the point. To delete a point, click the point while pressing Ctrl. To add a point, click the shape outline while pressing Ctrl. A vertex is the point, indicated by a black dot, where a curve ends or the point where two line segments meet in a freeform shape. On the Shape Format (or Format) tab, click Edit Shape, and then click Edit Points.ĭrag one of the vertexes that outline the shape. For example, you edit points when you need to lean a triangle over to the right. To close the shape, click near its starting point. To leave the shape open, double-click at any time. Sketch two lines, one parallel to W and one parallel to D, to complete the outline of the rectangular block as shown in Figure 6.2. To finish drawing the shape, do one of the following: To draw a straight segment with the Freeform tool, click one location, move your pointer to a different location, and then click again to draw a curved segment, keep your mouse button pressed as you drag to draw. Ĭlick anywhere in the document, and then drag to draw. To draw a shape that looks like it was drawn with a pen by hand, or to create smooth curves, click Scribble. To draw a shape that has both curved and straight segments, click Freeform. On the Insert tab, in the Illustrations group, click Shapes. Note: For information about connecting shapes with lines, see Draw or delete a line or connector.
