org.apache.cocoon.ProcessingException: Failed to execute pipeline.: java.lang.IllegalArgumentException: Width (0) and height (0) cannot be <= 0 Batik SVG cocoon bug???

Sun, 21 Mar 2004 04:12:03 -0800

Hi,
I think that i may have stumbled on a bug with usage of SVG in cocoon. I have a pipeline which takes in a jpg:

<map:match pattern="**artistImage/*/*.jpg">
<map:generate type="serverpages" src="xsp/svg.xsp">
<map:parameter name="imageNum" value="{3}"/>
<map:parameter name="artistID" value="{2}"/>
</map:generate>
<map:serialize type="svg2jpeg"/>
</map:match>

This in turn causes xsp:/svg.xsp to be processed. The code in svg.xsp is:

<xsp:structure>

</xsp:include>
</xsp:structure>

<svg width="100" height="100">
<xsp:logic>
String base64 = null;
String width = "300";
String height = "300";


try {
int imageNum = Integer.parseInt(<util:get-sitemap-parameter name="imageNum"/>);
int artistID = Integer.parseInt(<util:get-sitemap-parameter name="artistID"/>);


<!-- request made to static object -->
base64 = ArtistImages.getArtistImage(artistID,imageNum);


}catch (Exception e) {
width = "100";
height = "100";


<!-- request made to static object -->
base64 = ArtistImages.getArtistImage(<util:get-sitemap-parameter name="imageNum"/>);


}


<!-- spit the image back to the browser requester -->
<xsp:element name="image">
<xsp:attribute name="x"></xsp:attribute>
<xsp:attribute name="y"></xsp:attribute>
<xsp:attribute name="width"><xsp:expr>width</xsp:expr></xsp:attribute>
<xsp:attribute name="height"><xsp:expr>height</xsp:expr></xsp:attribute>
<xsp:attribute name="xlink:href">data:image/jpeg;base64,</xsp:expr></xsp:attribute>
</xsp:element>
</xsp:logic>
</svg>

The problem lays with the width and height attributes of the svg tag being specified as percentages. I specified them as so because I wanted the canvas size to same size as the image size. This causes the above mentioned error to be thrown. If I replace the width and height with whole sizes the problem is rectified. What is happening here as I know that Percentages are valid for the width and height of an svg!??

The full exception stack trace is:
