My name is Doug Schepers… and I’m an annotator.

You might be an annotator, too. If you think you might be, you should come to our support workshop in San Francisco in April.

Retain Accessibility Immediately

There has been a heated argument recently on the W3C Canvas API mailing list between accessibility advocates and browser vendors over a pretty tricky topic: should the Canvas API have graphical “objects” to make it more accessible, or should authors use SVG for that? I think it’s a false dichotomy, and I offer a proposal to suggests a way to improve the accessibility potential of the Canvas 2D API by defining how SVG and the Canvas 2D API can be used together.

This brings together some ideas I’ve had for a while, but with some new aspects. This is still a rough overview, but the technical details don’t seem too daunting to me.

Getting In Touch

Last week, I published the first draft (and subsequent updates) of the Web Interface specification, which defines touch events. This is the first spec from the new W3C Web Events Working Group.

Peter-Paul Koch (PPK) gave it a positive initial review. Apparently, others thought it was news-worthy as well, because there were a few nice write-ups in various tech sites. Naturally, cnet’s Shank scooped it first (he has his ear to the ground), and it was fairly quickly picked up by macgasm, electronista, and Wired webmonkey.

I thought I’d go into a few of the high-level technical details and future plans for those who are interested.

Pointers on Background of SVG Borders on Mutiny

August 21, 2010

Filed under: CDF,Standards,SVG,SVG 2,Technical,W3C,Work — Magister @ 5:37 pm

With SVG being integrated more and more into HTML5, both included via <object> and <img> elements, and inline in the same document, some natural questions about SVG and CSS are receiving more focus. This includes box model questions like background and border, and pointer events.

I’m interested in comments from the community on what direction SVG should take.

Getting to the Point

SVG paths have a pretty good set of shape commands, enough to let you draw any 2D shape you might want in an authoring tool: horizontal, vertical, and diagonal straight lines, elliptical arc segments, and cubic and quadratic Bézier curves. Béziers are great, giving you precise control over the position and curve interpolation of each point in a concise format, using control points (“handles”), and are easily chained together to create complex shapes.

But let’s say you have a series of points, and you want to draw a smooth line between them, e.g. for stock data, an audio wave, or a mathematical graphing equation. Béziers are not as handy there, because not all the points needed to define a Bézier spline are on the curve itself. Obviously, you can decompose any set of points into a set of Béziers, but that takes math, and who wants to do that? (Put your hand down, nerd. I’m talking to the normals.)

Sometimes, you just want to lay down a set of points, and let the browser draw a smooth curve (unlike polylines, where each segment is just a straight line between the points). Like this:

Please use a modern browser.

Slow News Day

Filed under: Meta,Search Engines,Standards,W3C,Work — Magister @ 12:38 am

My last post was slashdotted. Not servers-melting slashdotted, but unusual-volume-of-comments slashdotted. I posted it late on a Saturday night, so I guess they had no other news fit to print.

It was interesting, and a little bit exciting, to be linked from Slashdot. I have no great insights, but a few observations.
