Bar Charts: "Invert if negative" (CT_InvertSolidFillFmt)

[Exandra]

Hello,

Our chart library needs the word feature "Invert if negative" for solid fills (bar charts), but docx4j doesn't seem support them. At least I didn't find a way to unmarshal the required XML code or programmatically implement them.

"Invert if negative" is in Word implemented like this:

Code: Select all

               <c:extLst>
                  <c:ext uri="{6F2FDCE9-48DA-4B69-8628-5D25D57E5C99}" xmlns:c14="http://schemas.microsoft.com/office/drawing/2007/8/2/chart">
                     <c14:invertSolidFillFmt>
                        <c14:spPr xmlns:c14="http://schemas.microsoft.com/office/drawing/2007/8/2/chart">
                           <a:solidFill>
                              <a:srgbClr val="C0504D"/>
                           </a:solidFill>
                           <a:ln>
                              <a:noFill/>
                           </a:ln>
                           <a:effectLst/>
                        </c14:spPr>
                     </c14:invertSolidFillFmt>
                  </c:ext>
               </c:extLst>

The docx4j webapp is able to generate c:extLst and c:ext. Everything below that node is missing. The required tags are in chart20070802.xsd.

Before I try to implement the required classes by hand (ouch), I'd like to know whether someone from the docx4j team could commit these classes to the repository. Or maybe someone could explain how to generate these classes from the schema definition. I tried the following command:

Code: Select all

xjc chart20070802.xsd -d foo -no-header -target 2.0 –extension

But parsing failed with three warnings and one error.

• Warnings: Missing orel.xsd, oartspproperties.xsd, ChartDrawing.xsd, Chart.xsd.
• Error: a:CT_ShapeProperties couldn’t be resolved as “type definition”

Is there any chance to implement c14:invertSolidFillFmt, c14:spPr, a:solidFill ...?

Adding this now.

Will be in a nightly today or tomorrow and in the next release of docx4j (3.3.6) due later this week.

Note the other chart related namespaces at https://msdn.microsoft.com/en-us/librar ... =office.12).aspx

Are any others of those critical to you right now?

docx4j currently drops the mc:AlternateContent element. To address that, mc:AlternateContent would need to be added to the c:chartSpace content model.

If you need further help with c:extLst/c:ext, please attach a sample docx.

Thanks for the fast reply. I've run into a few problems to implement the final "Invert if negative" feature:

• JAXB couldn't initialize org.docx4j.dml.chart.x2007 context due to a missing ObjectFactory.class or jaxb.index.
• Missing XmlRootElement in CTInvertSolidFillFmt

I've created an ObjectFactory by Copy&Paste:

}


And I've added:

Code: Select all

import javax.xml.bind.annotation.XmlRootElement;
...
@XmlRootElement(name = "invertSolidFillFmt")

To my CTInvertSolidFillFmt.java.

Using the "XML unmarshal-way", I run into problems with the c: and a: namespaces. But I've never really used this way anyway. Probably a problem in front of my display and not a problem of docx4j.

But the programmatic way works for me, yeah.

JAXB couldn't initialize org.docx4j.dml.chart.x2007 context due to a missing ObjectFactory.class or jaxb.index.

XJC did generate OF, but somehow I didn't push it; done now: https://github.com/plutext/docx4j/commi ... 4cab67e018

@XmlRootElement(name = "invertSolidFillFmt")

Yes, that's ok here, so thanks, copied your code

Using the "XML unmarshal-way", I run into problems with the c: and a: namespaces.

If you give an example of what you mean, I'll try to help. Be sure you declare those namespaces.
