How to add rounded corners to any shape in Inkscape


 

Heads-up! Directly inserting svg files in Keynote is now possible, albeit limited editing possibilities. 

One of the things I struggled for years was to create rounded corners in shapes, until yesterday when I, thanks to Nick Sapurito's Inkscape Master Class,  learned about the Live Path Effect (LPE) called Corners. I have known about LPE for years, but always ignored until two months ago, when I had to bend text. Anyhow…

Quick tutorial

This is my starting point, an arrow with sharp edges:

0. Select the shape you want to apply the arounded corners.

1. Open the Live Path Effects dialog  by going to the Path Menu > Path Effects …

Don't ask me why people write and talked about Live Path Effects, but in inkspace is simply called Path Effects. Also note it has a direct shortcut.

2. This is inconvential, but I searched for the effect instead of directly clicking on it, just to keep you  focused:

3. As the next figure shows, this effect allows to add (or not) a corner to every edge, that's the little green circle call it a handle:

Note two things, that little green circle only appears when 1 the path has the corners effect applied to it, and 2 if the Node Tool is selected.

4. Now pull the handle down to rounded the select corner:

We're almost done! The Path object is no longer a simple Path object, if you look at the bottom of the window you'll see it has the live effect applied to it.


This is because LPEs are not destructive, that is you can always go back to the original Path.

5. If for some reason you want to bake the LPE into the Path, go to the Path Menu >  Object to Path.

Wait! But there is more…

For often than not, you want to rounded all edges of a path:

In this case you simple set the radius to a non-negative number, in my case 10px. Note how using a percentage is also possible. And especially note the buttons Fillet and Chamfer. A Fillet yields a rounded corner:

Whereas a Chamfer yields a straight line:


In case you might be wondering when you would use a corner like this, here is an example:

Presentation sin: Overtime

Going overtime in a presentation is a common failure in scientific presentations. However practicing your talk should prevent this from happening. The scene is unfortunately quite familiar. A professor or student has 90/60/25 minutes for his or her presentation and it goes overtime. While the speaker keeps talking, the students need to run to another lecture, the next speaker is annoyed, or the audience wants to go to the break. Although we know this shouldn't happen, we see it often at conferences and lecture halls. I thought it happened because people  did not practice enough. But a friend of mine, who also happens to be involved in academia, told me two weeks ago that is not always the case. She said professors and students go overtime to show that they have more say, that it shows their passion for the topic.  At first I was skeptical, but I started thinking about some  of the talks I have heard/ and delivered in the past, and realized it is also true. People overtime to sh

How to crop images with circles in Keynote

Image
Here is a way to deal with images that come in different sizes and/or orientations: mask them with circles.  Here is what I mean You have probably already seen this with Google and Apple productions. Circles are fun, dynamic, harmonious, and they are also points. Now, there is a whole visual grammar behind points, but that's not the topic of this post. Let's do the before-after thing. Consider this fake slide By the way, also Featured pictures from Wiki Commons. The images are very good, but we can take them to the next level.  Their sizes are around 700px, so I'll mask them with circles with a diameter of 300px. This is the result Certainly better, but how did I do it? Most Slideware packages allow you to crop an image with a shape .  Google it and you'll get the technical know-how. I'll demo with Keynote 6.   Select a Circle: Insert > Shape > Cicle. Make it the size that you want.  We'll rescale all images at the end, so don&

On why I hate LaTeX/Beamer

Image
Continuing with a last's year post, I make a case in point about how using LaTeX/Beamer is bad for scientific presentations.   Last year I wrote about LaTeX/Beamer and how it was worse than bad PowerPoint. One or two weeks ago I found a presentation on Slideshare done in Beamer, by people I know. They are excellent scientists at Germany's best research center. It is partly not their fault, they are applied mathematicians, and in mathematics LaTeX and, to a lesser degree Beamer,  are industry standards. The problem of using Beamer for scientific talks is that it employs the same narrative of a written essay: Title, introduction, first section, second subsection, conclusion. Another problem is that Beamer enforces the use of off-the-shelf templates, and the command-line nature of Beamer makes its customization very time consuming. The use of predefined templates one of the causes of  the death by PowerPoint. The creation of a math talk using Beamer is a soporific bomb. To sh
