Welcome to my tech tips blog!
I am a programmer and will mainly focus on new software information I learn in my day to day work. I will also post about any new, cool computer products I hear about and any other computer related information I find useful. Enjoy & feel free to leave comments any time.
Apache Batik<\/a>, a toolkit for drawing svg <\/a>in java. It also does other miscellaneous svg related things such as generating an svg or converting an svg<\/a> to jpeg, gif or png. It’s very cool. All free and open source, my favorite kind of software. Ok, so I’ve been trying to define a stroke in svg<\/a>, a line in java & use batik<\/a> to draw the line using the defined stroke in a web browser. There’s very little online in terms of tutorials for batik<\/a>. The batik<\/a> site is about the only one for tutorials. Well, I managed to get it working. SVG<\/a> is very cool! In the svg<\/a> I created a cdata section, defining 3 strokes like this:
.black12 {stroke:rgb(0,0,0);stroke-width:12}
.yellow8 {stroke:yellow;stroke-width:8}
.red2 {stroke:red;stroke-width:2}
Then add a group section:
g id=”street”>
use xlink:href=”#geometry_path” class=”black12″ \/>
use xlink:href=”#geometry_path” class=”yellow8″ \/>
use xlink:href=”#geometry_path” class=”red2″ \/>
\/g><\/p>\n

Note: < needs to be added to the front of each line. I'm having problems displaying the lines when I use <.\n\n In java, I create an applet in which I do the following:\n\n String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
String uri = getCodeBase()+”svg\/stroke.svg”;
SVGDocument doc = (SVGDocument)f.createDocument(uri);<\/p>\n

\/\/ get the root element (the svg element)
Element svgRoot = doc.getDocumentElement();<\/p>\n

Element defs = doc.createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI, “defs”);<\/p>\n

\/\/ create a line
Element line = doc.createElementNS(SVGDOMImplementation.SVG_NAMESPACE_URI, “line”);
line.setAttributeNS(null, “id”, “geometry_line”);
line.setAttributeNS(null, “x1”, “10”);
line.setAttributeNS(null, “y1”, “20”);
line.setAttributeNS(null, “x2”, “150”);
line.setAttributeNS(null, “y2”, “100”); <\/p>\n

defs.appendChild(line);<\/p>\n

\/\/ attach the rectangle to the svg root element
svgRoot.appendChild(defs);<\/p>\n

svgCanvas = new JSVGCanvas();
\/\/ Set size of svg canvas
svgCanvas.setMySize(new Dimension(500, 500));
\/\/ Set background color of svg canvas
svgCanvas.setBackground(new Color(255, 255, 255));
svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
svgCanvas.setDoubleBufferedRendering(true);
svgCanvas.setSVGDocument(doc);<\/p>\n

One thing I learned is the stroke id names can’t contain an underscore. Example black12 can’t be black_12. Interesting.
Anyways, if you’re interested in learning svg<\/a>, check out this book:SVG Programming: The Graphical Web<\/a>\"\" by Kurt Cagle. I just ordered and it seems pretty useful. I’m also thinking about ordering this book: Java Drawing with Apache Batik: A Tutorial<\/a>\"\" by Alexander Kolesnikov, Budi Kurniawan, Paul Deck. Other than the batik site<\/a>, this is the only other batik<\/a> tutorial I have found. Please let me know if you know of any other batik<\/a> books or sites.<\/p>\n","protected":false},"excerpt":{"rendered":"
