<br><br><br>> My previous post with same topic has some error, so I'm sending it again.
<br><br>Weird... In fact I received the previous message properly (i.e., in my
<br>email) but it doesn't display well in the official mailing list
<br>archive [1]. An unofficial archive displays it as expected [2],
<br>though...
<br><br>I'd suggest that, when creating a new thread, you didn't forward from
<br>another thread (apparently this was the case) nor reply to a previous
<br>thread and change subject (also a common mistake), as this may confuse
<br>the mailing lists: as a reply/forward messages have embedded metadata
<br>about the original message, the "new" thread may not appear as desired
<br>(typically, for replies it is displayed out of order).
<br><br><br>Regards,
<br> Helder

<br><br>I want to insert JGVTComponent into JScrollPane and have the cavas
<br>(component) as large as SVG document. The problem is that for large
<br>zooms rendering of whole svg extend consumes lots of memory, the
<br>simplest way to avoid this is to render only currently visible box of
<br>scroll pane and update the rendered part on the viewbox change. I've
<br>tried to override getRenderRect method of JGVTComponent but it only
<br>refreshes JGVTComponent and not svg content itself. I've attached
<br>simple test (SVGApplication.java)
<br><br>Is there a way to force rendering of specified svg content on
<br>JGVTComponent (or any other panel) in explicitly pointed area ?
<br>best regards

<br><br>I used your line taken from [1], and it worked. Apparently, you have to
<br>pass a qualified attribute name which includes the prefix. This is even
<br>specified in the org.w3c.dom.Element interface.
<br><br>I also browsed the SVN repository, and it seems that XLinkSupport is
<br>still omitting the prefix. The current code (revision 475477) is
<br><br>public static void setXLinkHref(Element elt, String str) {
<br> elt.setAttributeNS(XLINK_NAMESPACE_URI, XLINK_HREF_ATTRIBUTE, str);
<br>}
<br><br>where XLINK_HREF_ATTRIBUTE = "href".
<br><br>It probably should be
<br><br>elt.setAttributeNS(XLINK_NAMESPACE_URI, XLINK_HREF_QNAME, str);
<br><br>with XLINK_HREF_QNAME = XLINK_PREFIX + ':' + XLINK_HREF_ATTRIBUTE.
<br><br>Same goes for all other attribute getters and setters in XLinkSupport.
<br>Should I maybe file a bug somewhere or are these functions intended to
<br>work in another way?
<br><br>Regards,
<br>Gerrit
<br><br><div class='shrinkable-quote'><br>> I have a couple of suggestions:
<br>>
<br>> // XLinkSupport.setXLinkHref( useElement, "somefile.svg#someid" );
<br>> // use DOM2 instead. a tightly related sample is in the FAQ [1]
<br>> // (more related information is available in the website [2] and in
<br>> the mailing list archives [3])
<br>> useElement.setAttributeNS("<a href="http://www.w3.org/1999/xlink" target="_top" rel="nofollow">http://www.w3.org/1999/xlink</a>",
<br>> "xlink:href", "somefile.svg#someid");
<br>>
<br>> // I'd suggest appending to the document only after completely setting it up
<br>> // (this may hold performance benefits in some situations)
<br>> doc.getDocumentElement().appendChild(useElement);
<br>>
<br>> If the above doesn't help, I'd also suggest attempting with the
<br>> current trunk version [4]: I recall a couple of namespace-related
<br>> fixes post the 1.7 release. ;-)
<br>>
<br>> Hope this helps,
<br>> Helder

<br>(In reply to comment #4)
<br>> Seems there is a problem with creating the BufferedImage used by
<br>> doubleBuffering. See Bug 48407. This might also be the reason for _this_ bug
<br>> (?).
<br><br>What occurs to me is not the double buffering but embedding (raster) images
<br>instead: Cameron wasn't able to reproduce the issue as probably the "test.svg"
<br>used didn't use any images (either embedded or linked). If so then, as stated
<br>in bug 48407 comment 1, this was likely fixed in revision 793536.
<br><br>Please try again using a nightly version [1] (or using the trunk source code
<br>[2]) and report back. In any case, a testcase would be helpful...

<br>> For realistic displaying we colorize the svg model with a graphic, which is
<br>> embedded in svg document. The png-graphic is having a certain color gradient,

<br><br>I just took a look at the document and the image format isn't PNG but JPEG. ;-)

<br>Could you please download a nightly build [1] and try reproducing the issue

<br>> The problem is in the last line. The script should read as follows:
<br>[...]

<br>> "`dirname \"$0\"`/../Resources/batik-squiggle.jar"
<br><br>I've checked that this is still present [1] in the trunk version, so I'm

<br><br><br>Response inline...
<br><br><br>> Running the above code with Batik 1.6 or 1.7 produces the following
<br>> output:
<br>[output]
<br>>
<br>>
<br>> Not only is the xlink namespace added a second time (it was already

<br>> Am I maybe missing something? What would be the correct way to add an

<br>> method is used to create the other xlink attributes that are lined up so
<br>> nicely?
<br><br>I have a couple of suggestions:
<br><br>// XLinkSupport.setXLinkHref( useElement, "somefile.svg#someid" );
<br>// use DOM2 instead. a tightly related sample is in the FAQ [1]
<br>// (more related information is available in the website [2] and in
<br>the mailing list archives [3])
<br>useElement.setAttributeNS("<a href="http://www.w3.org/1999/xlink" target="_top" rel="nofollow">http://www.w3.org/1999/xlink</a>",
<br>"xlink:href", "somefile.svg#someid");
<br><br>// I'd suggest appending to the document only after completely setting it up
<br>// (this may hold performance benefits in some situations)
<br>doc.getDocumentElement().appendChild(useElement);
<br><br><br>If the above doesn't help, I'd also suggest attempting with the
<br>current trunk version [4]: I recall a couple of namespace-related
<br>fixes post the 1.7 release. ;-)
<br><br><br>> Thanks for any insights.

The problem is that for large zooms rendering of whole svg extend consumes lots of memory, the simplest way to avoid this is to render only currently visible box of scroll pane and update the rendered part on the viewbox change. I've tried to override getRenderRect method of JGVTComponent but it only refreshes JGVTComponent and not svg content itself. I've attached simple test (SVGApplication.java)<br>
<br>Is there a way to force rendering of specified svg content on JGVTComponent (or any other panel) in explicitly pointed area ? <br>

<br>the corrected Squiggle.app/Contents/MacOS/Squiggle shell script
<br><br>Overview:
<br>The Mac OS X application bundle for Squiggle (a GUI front-end for Batik)
<br>refuses to run if it is installed in a path containing spaces, and possibly
<br>some other odd characters. However, it does not produce any error messages; it
<br>just doesn't start.
<br><br>Steps to Reproduce:
<br>1. Create a folder whose name contains one or more spaces.
<br>2. Download the Mac OS X disk image from
<br><a href="http://xmlgraphics.apache.org/batik/download.cgi#Download+a+distribution" target="_top" rel="nofollow">http://xmlgraphics.apache.org/batik/download.cgi#Download+a+distribution</a><br>3. Most OS X native browsers will mount the disk image automatically. If your
<br>browser is a ported browser that doesn't do this, find the downloaded disk
<br>image and double-click on it to mount it.
<br>4. Install the Squiggle application by dragging it from the disk image to the
<br>folder created in step 1, or to a sub-folder of a folder whose name contains
<br>one or more spaces.
<br>5. Un-mount (eject) the disk image.
<br>6. Double-click on the installed Squiggle application to launch it.
<br>7. When the computer displays the message '“Squiggle” is an application which
<br>was downloaded from the Internet. Are you sure you want to open it?' click
<br>Open.
<br><br>Actual Results:
<br>The Squiggle icon that appeared in the Dock in step 7 disappears. On
<br>subsequent attempted launches (when the computer does not ask for confirmation)
<br>the icon appears very briefly in the Dock and then disappears. No splash
<br>screens etc appear. The following is written to the Console (which can be read
<br>by opening /Applications/Utilities/Console.app):
<br><br>Dec 18 15:45:25 Beetle [0x0-0x135135].org.apache.batik[77397]: usage: dirname
<br>path
<br>Dec 18 15:45:25 Beetle [0x0-0x135135].org.apache.batik[77397]: Unable to access
<br>jarfile /../Resources/batik-squiggle.jar
<br>Dec 18 15:45:25 Beetle com.apple.launchd[158]
<br>([0x0-0x135135].org.apache.batik[77397]): Exited with exit code: 1
<br><br>Expected Results:
<br>The Squiggle application should launch, display a splash screen and continue to
<br>run, and its icon should remain in the Dock until the user desires the
<br>application to quit.
<br><br>Build Date & Platform:
<br>Build 2008-01-06 on Mac OS 10.5.8
<br><br>Additional Builds and Platforms:
<br>This only affects the Mac OS X application. The JAR file works just fine.
<br><br>Additional Information:
<br>I know how to fix this.
<br><br>Inside the Mac OS X application bundle (applications on OS X are really just
<br>folders whose name ends in '.app') there is a file at
<br>Squiggle.app/Contents/MacOS/Squiggle. It is an executable shell script that is
<br>run when the user double-clicks on the application. It attempts to start up
<br>the JAR located at Squiggle.app/Contents/Resources/batik-squiggle.jar. It is
<br>this file that contains the bug. This script reads as follows:
<br><br>#!/bin/sh
<br><br>JAVA=/usr/bin/java
<br>[ -e "$JAVA_HOME/bin/java" ] && JAVA="$JAVA_HOME/bin/java"
<br><br>"$JAVA" -Dcom.apple.mrj.application.apple.menu.about.name=Squiggle -jar
<br>"`dirname $0`/../Resources/batik-squiggle.jar"
<br><br>The problem is in the last line. The script should read as follows:
<br><br>#!/bin/sh
<br><br>JAVA=/usr/bin/java
<br>[ -e "$JAVA_HOME/bin/java" ] && JAVA="$JAVA_HOME/bin/java"
<br><br>"$JAVA" -Dcom.apple.mrj.application.apple.menu.about.name=Squiggle -jar
<br>"`dirname \"$0\"`/../Resources/batik-squiggle.jar"
<br><br>I have also attached the corrected script.

When I add an
<br>xlink:href attribute to my document, the xlink namespace is omitted,
<br>making the attribute invalid. I am using the following code:
<br><br><br>SVGDOMImplementation impl = (SVGDOMImplementation)
<br>SVGDOMImplementation.getDOMImplementation();
<br>AbstractDocument doc = (AbstractDocument)
<br>impl.createDocument(SVGConstants.SVG_NAMESPACE_URI,
<br>SVGConstants.SVG_SVG_TAG, null);
<br>Element useElement = impl.createElementNS(doc,
<br>SVGConstants.SVG_NAMESPACE_URI, SVGConstants.SVG_USE_TAG);
<br>doc.getDocumentElement().appendChild(useElement);
<br>XLinkSupport.setXLinkHref( useElement, "somefile.svg#someid" );
<br><br>StringWriter writer = new StringWriter();
<br>try {
<br> DOMUtilities.writeDocument(doc, writer);
<br> System.out.println( writer.toString() );
<br>} catch (IOException e) {
<br> e.printStackTrace();
<br>}
<br><br><br>Running the above code with Batik 1.6 or 1.7 produces the following
<br>output:
<br><br><br><?xml version="1.0" encoding="UTF-8"?>
<br><svg xmlns:xlink="<a href="http://www.w3.org/1999/xlink" target="_top" rel="nofollow">http://www.w3.org/1999/xlink</a>"

<br></svg>
<br><br><br>Not only is the xlink namespace added a second time (it was already
<br>present in the root element), but the namespace prefix is missing in the
<br>href attribute. Since attributes, unlike elements, have no default
<br>namespace, the attribute is not a valid xlink:href attribute any more.
<br>When loading the serialized document, Batik correctly throws an error:
<br><br>The attribute "xlink:href" of the element <use> is required
<br><br>The funny thing is, when I just add the attribute and render the DOM
<br>tree without serializing it, the reference is accepted, GVT nodes are
<br>created and the referenced element shows up on the screen. I therefore
<br>suspect that some error occurs during serialization.
<br><br>Am I maybe missing something? What would be the correct way to add an
<br>xlink:href reference, or a use element with default attributes? What
<br>method is used to create the other xlink attributes that are lined up so
<br>nicely?
<br><br>Thanks for any insights.

make a test program, and get it to compile. But if I try to use the
source files (all the files under the “sources/” folder) instead to
compile, I cannot because there’re at least several other libraries for
which I’m missing the source code. Are the source files purely for
reference only? They are not supposed to be used for compiling? Or
is there something I’m doing wrongly? How are most people using Batik?<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

with a library as large as Batik, is it generally better to edit the source
files directly and then compile them, or is it the preferred way to extend
existing classes? I ask because I am running into situations where I want
to add features to a class that might be used by many other classes, but I don’t
want to go through and extend all those other classes to make sure that they
use my modified class instead. Since that might sound a bit confusing,
let me put forward a theoretical example:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Suppose there is a class Graph, which uses a class Rectangle,
which uses a class Edge. The class Graph also has access to the Edge
class to make lines. Now, let’s say I made a new class, called
MyEdge, which extends class Edge. I want both Graph and Rectangle to use
this new class instead. Is there a way to do it without having to make
new classes called MyGraph and MyRectangle to reference the new class? <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Sorry if my question might not be really appropriate, but I’m
just wondering since I’ve been looking at the JSVCanvas class in Batik,
and as right now I cannot seem to get the source files to compile and am instead
relying on the .jar library files, I’m trying to think of how I could
extend classes used by that class without having to extend everything in
between. If there’s also another resource to which I could turn
that might better answer this question, please let me know. <o:p></o:p></span></font></p>

<br>Seems there is a problem with creating the BufferedImage used by
<br>doubleBuffering. See Bug 48407. This might also be the reason for _this_ bug
<br>(?).

<br>SVG document, having a grafic with color gradient in background for more
<br>realisitc appearance
<br><br>We are using batik for displaying human bodies for locating their body parts.
<br>For realistic displaying we colorize the svg model with a graphic, which is
<br>embedded in svg document. The png-graphic is having a certain color gradient,
<br>for more realistic appearance.
<br><br>Problem:
<br>If we are zoom in serveral times (shift-right mouse pressed and move up,
<br>-Xmx256M) with this svg document [see attachment], we do gain a
<br>java.lang.OutOfMemoryError.

<br>SVGTextPositioningElement (getExtentOfChar does not return null even

<br><br>In the interest of making others' lives easier (pay it forward),

<br><br>It is not difficult to do that. The first thing you need to do is to use
<br>the coordinate system of your specific map using the viewbox attribute
<br>on the SVG element. After that you can create whatever object on the
<br>fly. I did this for a project we had with the Dutch DOT. We made the

<br>will find a huge set of useable tools)

<br>> a map. I am using swing, so I want to use the JSVGCanvas.html
<br>> <<a href="http://xmlgraphics.apache.org/batik/javadoc/org/apache/batik/swing/JSVGCanvas.html" target="_top" rel="nofollow">http://xmlgraphics.apache.org/batik/javadoc/org/apache/batik/swing/JSVGCanvas.html</a>> to
<br>> do most of the work, except I need to store the features to be
<br>> rendered in the SVG file in terms of their geographic locations
<br>> (latitudes and longitudes), and then convert these into the pixel
<br>> coordinates on the fly based on the current type of projection (e.g.
<br>> Lambert, Mercator, etc), scale and location. I have the code to do
<br>> these conversions, however, I'm not sure where to hook it in. Would I
<br>> extend/write a bridge to do this?
<br>>
<br>> Any help would be greatly appreciated.

<br>To summarize:<br><br> urq.invokeLater(new Runnable() {<br> public void run() {<br> Text t = document.createTextNode(text);<br> textNode.replaceChild(t, textNode.getFirstChild());<br>
...<br> SVGRect altbounds = locatable.getBBox();<br> }<br> });<br><br>Would likely fail because the text has yet to be rendered (hence the size has not been calculated?)<br>
<br>You can easily get around this using 2 worker threads in succession. Perform the Locatable bounding box operation in the second one:<br><br> urq.invokeLater(new Runnable() {<br>
public void run() {<br>
Text t = document.createTextNode(text);<br>
textNode.replaceChild(t, textNode.getFirstChild());<br>
}<br>
});<br>
urq.invokeLater(new Runnable() {<br>
public void run() {<br>
...<br>
SVGRect altbounds = locatable.getBBox();<br>
}<br>
});<br>
<br><br><br>If I've missed the mark, please try to provide some additional information.<br><br><br><br><div class="gmail_quote">On Sun, Dec 13, 2009 at 11:24 PM, Brendon J.

<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">After a couple hours of Googling and hacking, it would appear time to send an email to this list to see if there's a solution I'm missing.<br>
<br>
The Desired Result: An area of text that uses the largest font size possible while still fitting into a given rectangle.<br>
<br>
The Proposed Solution: Use the 'flowroot' element, check for overflow, and iteratively adjust the font size of the text.<br>
<br>
The Problem: Based on emails from this list dating from 2006, it does not appear overflow events are implemented, and my alternative attempts to formulate my own overflow detection mechanism have been unsuccessful.<br>
<br>
The SVG:<br>
---<br>
<?xml version="1.0" encoding="utf-8"?><br>
<svg version="1.2" xmlns="<a href="http://www.w3.org/2000/svg" target="_blank" rel="nofollow">http://www.w3.org/2000/svg</a>" x="0px" y="0px" width="982px" height="1200px" viewBox="0 0 982 1200"><br>
<br>
...<br>
<br>
<flowRoot xml:space="preserve"><br>
<flowRegion vertical-align="middle"><br>
<rect x="74.472" y="376.98" width="833.958" height="296.985" id="bounding"/><br>
</flowRegion><br>
<br>
<flowDiv><br>
<flowPara justification="middle" top-margin="10" left-margin="10" right-margin="10" bottom-margin="10" fill="#331C1D" font-family="'Futura-Medium'" font-size="72" id="title"><flowLine>Some interesting text</flowLine></flowPara><br>
</flowDiv><br>
</flowRoot><br>
</svg><br>
---<br>
<br>
While this code allows me to get the rectangle into which I'm flowing text:<br>
---<br>
SVGElement svgElement = (SVGElement) doc.getElementById("bounding");<br>
SVGLocatable locatable = (SVGLocatable) svgElement;<br>
SVGRect altbounds = locatable.getBBox();<br>
---<br>
<br>
but a similar call to attempt to get the bounding box for the laid out text (I presume, I'm actually shooting in the dark at this point) results in an uncaught exception:<br>
<br>
---<br>
SVGElement svgElement = (SVGElement) doc.getElementById("title");<br>
SVGLocatable locatable = (SVGLocatable) svgElement;<br>
SVGRect altbounds = locatable.getBBox();<br>
---<br>
<br>
Even if I move the id="title" to the flowDiv, the result is the same. So I'm at a bit of a loss.<br>
<br>
Is there another, easier way to figure out the actual dimensions of the laid out text in a flowDiv, or check the flowRoot for overflow? Or are overflow events still not implemented?<br>
<br>
Thanks in advance,<br>
<br>
