Vector Magic: The tech that could, the company that could not

Vector Magic originated as a free online service hosted at Stanford University. You could upload a raster image, such as clip art or a photo, and use the service to generate a vector-based image. You could then export the image in a format such as SVG.

The service was simple to use and did an excellent job, especially if you’re not experienced with using tools like Adobe Illustrator or Inkscape’s Trace functionality.

The developers behind Vector Magic split their software off from Stanford, creating a company named Vector Magic and began to offer the web services for a price. Unfortunately, the price was high: to download a vectorized image would cost about $2.50 American, which ended up being too steep for most folks.

The company then came out with a monthly “all you can download” subscription service, costing $7.95 a month. That’s not a bad price for the service. However, the company also demands that you maintain a credit card on file, which is something I’ve never been comfortable with. Again, a case of good technology but not the best business practices.

I looked forward to the long awaited Desktop tool, where I could create as many vectorized images I wanted without having to pay $2.50 per vectorized download, or tie into a monthly subscription service that wants to keep my credit card on file.

Vector Magic just announced the release of their first desktop product, this one for the PC. The Mac version will following in a couple of months. This is a production release—if there was a beta release, it wasn’t public. I tried the application and it is very efficient, and does a terrific job at converting raster images into vectors. For one license you can also run the application on two machines, though you have to activate the license on each machine over the internet. If something happens to one machine, an email to the company should be enough to open the license for install on another machine. Should be enough, as there is no formal deactivation process, like you would have with Photoshop.

However, the cost of the application is $295.00. This is more money than I’m willing to pay for a tool just to make a vector conversion of an occasional raster image. I’m not one to begrudge people making money off their work and products, but I’ve been effectively priced out of Vector Magic’s market. It’s time for me to return to an open source tool like Inkscape and regretfully leave Vector Magic for those whose use of the product either justifies the cost, or who have deeper pockets than mine.

Picnik your Flickr

How many misspellings does it take to make a successful mashup?

Elaine posted a note about Flickr adding edit capability via Picnik. I immediately tried it out, as the following screenshots demonstrate:

[images lost]

Just as with the stand alone version of Picnik, some of the functionality is free, others are part of a premium package: $24.95 per year.

Picnik is one of the few online photo editors I did include in the book, primarily because it’s one of the better organized, and has some of the most interesting effects. One aspect I like most about it is the sliding scale tool, which provides live scaling of the image.

Picnik uses Flash, like all of the online photo editors do. Flash isn’t a requirement, though. Most of the functionality, and then some, that Picnik can do can be done with something that most people already have installed at their linux-based hosting site: ImageMagick.

To use the ImageMagick, you do need to have command line access through SSH. ImageMagick can also be installed on the Mac using Macports, and accessed via the Terminal application. Once installed, the following command:

convert purpledragon_thumb.jpg -bordercolor white \ -background DarkGray -polaroid 5 purplepolaroid.png

Creates the following effect.

Or, you can use Picnik with the premium package.

Experiments: SVG Clock

I thought I would go into some detail on some of the experiments I’ve been trying out on the site, starting with the SVG clock in the sidebar.

A major advantage of SVG is that you can actually see how something is created. Try that with a Flash file.

The SVG clock in the sidebar is an adaption of a very simple SVG clock created by Jason Davis. I modified it by creating specific second tick actions, and then altering the appearance. I also added code so that it would reflect my time, not yours. I figured you had your computer clock and didn’t need me repeating it.

The clock is LGPL so you can copy the SVG file directly into your own space, set the width of the container, and even alter the coloring if you wish. I’m using linear gradients to create a clock highlight, interior shadow, and silvery frame. I also added a Gaussian blur as shadow, but this only shows up in Firefox 3, Opera, and Safari.

The function to change to your time zone is:

setInterval("setClock(calcTime(-6))", 1000);

The value to change is “-6”, which states that my timezone is currently 6 hours behind GMT.

It’s just a frill, true, but after seeing some of the crap I’ve seen in sidebars, you could do worse. It takes up less CPU than most animated ads, and requires no external load times. From a browser performance perspective, Safari requires less CPU to run the clock than Firefox or Opera. If you load the clock directly, it will be quite large, but will also eat up considerable CPU. Leave it up for a while and I guarantee your computer’s fan will come on.

Is the clock worth the extra burden on the client’s machine? Yes, and no. As a demonstration of what you can do with SVG and simple animation, I think it’s a valuable tool. There is a Catch 22 about SVG: we don’t use SVG because browser support is incomplete or inefficient; effort to better incorporate SVG is of secondary importance because SVG is little used. The only way to break this cycle is to actually start using the specification, and pushing a bit at the edges while we go about it.

As for the contents of the clock, how much do your web page readers really care about what time is it where you’re at? I would have thought probably not a whole lot, but I find that I’m not particularly good at understanding what particular bits of minutia interest people. I’m told people want to know you bought chewing gum–the brand, the flavor, the date and time when purchased. What time it is where you live must seem monstrously important in comparison.
