Scalable Vector Graphics -- or SVG -- is the new XML-based graphics standard from the W3C that will enable Web documents to be smaller, faster and more interactive. J. David Eisenberg's insightful book takes you through the ins and outs of SVG, beginning with basics needed to create simple line drawings and then moving through more complicated features like filters, transformations, and integration with Java, Perl, and XSLT.Unlike GIFs, JPEGs or PNGs (which are bitmapped), SVG images are both resolution- and device-independent, so that they can scale up or down to fit proportionally into any size display or any Internet device -- from PDAs to large office monitors and high-resolution printers. Smaller than bitmapped files and faster to download, SVG images can be rendered with different CSS styles for each environment. They work well across a range of available bandwidths.SVG makes it possible for designers to escape the constant need to update graphics by hand or use custom code to generate bitmap images. And while SVG was created with the Web in mind, the language has a variety of other uses. SVG greatly simplifies tasks like:
- Creating web sites whose graphics reflect the content of the page, changing automatically if the content changes
- Generating graphs and charts from information stored in a wide variety of sources
- Exchanging detailed drawings, from architectural plans to CAD layouts to project management diagrams
- Creating diagrams that users can explore by zooming in and panning around
- Generating bitmap images for use in older browsers using simple automatable templates
- Managing graphics that support multiple languages or translations
- Creating complex animation
Many of the examples don't work, or only work in some browsers but not others; like so much else, the topic of browser support is simply ignored. At least a couple of the example illustrations don't match the code examples shown.
The index is simply atrocious. Keyword after keyword is completely absent, and much of what is listed points to the wrong page, or is useless cruft produced by an obviously misguided auto-indexing tool of some sort. If you need to find something fast, you'll be reaching for your favorite search engine in frustration, because you won't find it here.
If you're just getting started with SVG, this slim volume may be helpful for the first week or so. Then, you'll be pining for a true, comprehensive guide to SVG.
For the time being the book earns it's four stars by providing a nice learning curve and having high quality examples that demonstrates the concepts effectively.
SVG, a refactoring of several generations of Web technology and a public standard approved by the World Wide Web Consortium, can be authored without any special tools and without any special background, other than the immediately productive background provided by this book.
Eisenberg swiftly, but with diverting variety, illuminates the process of drawing, assembling shapes, creating textures, transforming coordinates, structuring documents, enriching text, creating reusable components, fine tuning color, animating shapes and colors and structures, creating lighting effects, and programming user interactions. All of this is built upon the simple SVG architecture: arrange your elements in a hierarchy and set their attributes.
There is an art to conveying important points without belaboring them and Eisenberg moves from example to example with perfect pitch.
The book also contains an eight page section with full color images.
Some people have complained about the lack of reference books on SVG. The SVG reference is in fact widely available, all 500+ pages of it, on the W3C site. What is really needed, and would have been useful in this or any SVG book, is a five page guide to using that reference -- how do I, in ten seconds or so, determine whether this element can be a child of that element, or if this element supports this attribute?
While I was developing SVG Composer the only book available was Watt's "Designing SVG Web Graphics" (another fine book with a rather different pitch).. When Eisenberg's work came out I happily relearned SVG, doing every example and picking up any number of new tricks.
I do have some reservations: I didn't care for the cat drawing (hated it!) and the final two chapters on generating and serving SVG seemed aimed at the wrong audience (adepts at Java, servlets, and Perl) though the material itself is perfectly fine.
At first I had the same feeling about the appendices, which include brief samples of subjects from programming to fonts to matrix algebra, that surely Eisenberg was misjudging his audience. However he may have things just right -- SVG may well become the greatest crossover hit ever in computer languages, a lingua franca for logic and art.
