This is another effect where the UI seems to be upside down – all the interesting things are in the bottom section. The buttons at the bottom act as a set of toggles, enabling and disabling different types of transformation. Begin by activating the “Elastic” and “From original width” buttons. If you now switch to the Node tool (F2) you should see that a thin blue line with diamond handles has appeared on your path.** | This is another effect where the UI seems to be upside down – all the interesting things are in the bottom section.

**Drag either of the handles around on the canvas and you’ll see your path dynamically stretch and rotate in a very intuitive manner. Leave the “From original width” button enabled but try toggling some of the others on and off to see what effect they each have. It should be clear that this is a very fast and natural way to transform a path so that it fits in a specific gap, or connects visually to other elements in your drawing. | **Drag either of the handles around on the canvas and you’ll see your path dynamically stretch and rotate in a very intuitive manner.

I quite like this effect, but I find it disappointing because it’s just that – an effect. It would be so much better to see a transform option like this make its way into the roster of top-level tools in Inkscape. That would allow you to use the same sort of intuitive control whether you’re transforming paths, shapes, groups or even text.** | I quite like this effect, but I find it disappointing because it’s just that – an effect.

**Next in the roster of effects is “Interpolate Points”. This simply redraws your path using one of five pre-defined interpolations between the nodes. The UI is so minimal that I’m not even going to bother with a screenshot – it’s just a pop-up menu to let you select the type of interpolation you want to use. There’s no way to change the Bézier handles or otherwise adjust the curves, and the selected interpolation is applied to all the path segments; there’s no way to have different values applied to each individual segment or even sub-path. This effect is probably of most use as part of a chain with other LPEs, when you want to change the output of a previous step from straight lines to curves, or vice-versa – but otherwise there’s rarely any good reason to use this effect in preference to modifying your original path. Here’s an example of a simple path rendered using each of the five options: | **Next in the roster of effects is “Interpolate Points”.

The last effect I’ll be covering this month is “Join Type”. This lets you set the type of join used between path segments, in much the same manner as the Stroke Style tab of the Fill & Stroke dialog – except that it does have a couple of new tricks up its sleeve, and a big limitation to be aware of. On adding this effect to a path, you’ll be presented with this interface: | The last effect I’ll be covering this month is “Join Type”.

**The Line Cap pop-up offers the usual options of Butt, Rounded and Square line ends. But it adds a new option as well: Peak. This gives the line ends a slight point, but there are no further options to set the size or angle of the shape. It’s certainly no replacement for the Taper Stroke effect. The Line Width control, on the other hand, offers no surprises. It just alters the width of the stroke. | **The Line Cap pop-up offers the usual options of Butt, Rounded and Square line ends.

**With the Mitre Clip join type, and Force Mitre turned off, the Mitre Limit control takes on a new purpose. Rather than switching the join to beveled, the mitre is drawn - but cut off, as though truncated by a clipping path, at the length specified in this widget. When dealing with very sharp angles, it provides something of a halfway house between the excessive length of a full mitre and the stubby corner of a bevel. The example below shows a simple path rendered using Beveled, Mitre, Mitre Clip and Rounded joins, with Butt, Peak, Rounded and Square line caps. | **With the Mitre Clip join type, and Force Mitre turned off, the Mitre Limit control takes on a new purpose.

**Now for the elephant in the room – and it’s the usual pachyderm that we’ve encountered numerous times when looking at path effects. In order to remain compatible with SVG, the Inkscape developers haven’t just added their own line cap and join types to the file format. Instead, as with the Power Stroke and Taper Stroke effects, the results you see here are produced by rendering the path as a filled object. So if you want to use the beautiful extrapolated arcs (or the less impressive peak cap) on an object with a fill, you’ll have to use one of the usual roster of workarounds that I’ve covered in the past – whether that’s manually maintaining a second copy of the object to hold the fill, or using the Fill Between Many LPE to create a clone of your shape for filling. | **Now for the elephant in the room – and it’s the usual pachyderm that we’ve encountered numerous times when looking at path effects.
