Hello,

I see some differences between Oxygen Standalone Editor and Oxygen Author Web Component (Applet) in mathml formulas visualization. For example, this content:

Code: Select all


<math type="presentation">

					<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"

						display="block">

						<mml:semantics>

							<mml:mrow>

								<mml:mrow>

									<mml:mi mathvariant="bold">a</mml:mi>

									<mml:mo>=</mml:mo>

									<mml:mfrac>

										<mml:mrow>

											<mml:mi mathvariant="bold">F</mml:mi>

										</mml:mrow>

										<mml:mi>m</mml:mi>

									</mml:mfrac>

									<mml:mo>=</mml:mo>

									<mml:mfrac>

										<mml:mrow>

											<mml:mi>q</mml:mi>

											<mml:mo>[</mml:mo>

											<mml:mi mathvariant="bold">E</mml:mi>

											<mml:mo>+</mml:mo>

											<mml:mfenced>

												<mml:mrow>

													<mml:mi mathvariant="bold">v</mml:mi>

													<mml:mi>X</mml:mi>

													<mml:mi mathvariant="bold">B</mml:mi>

												</mml:mrow>

											</mml:mfenced>

											<mml:mo>]</mml:mo>

										</mml:mrow>

										<mml:mi>m</mml:mi>

									</mml:mfrac>

								</mml:mrow>

							</mml:mrow>

						</mml:semantics>

					</mml:math>

				</math>

is visualized in Standalone Editor(16.1) in author mode well as an image. But the author mode in the applet does not resolve this formula to an image and just shows a root math:ml tag.
Is it possible to integrate maybe some additional css-styles or libraries to the Web component to be able to present math formulas like in Standalone Editor?

Thanks,
Yury.

Hi Yuri,

You would need the JEuclid libraries added to the applet's JNLP.
If you are using the Maven-based 16.1 SDK you would need to add a dependency in the pom.xml:

http://www.oxygenxml.com/doc/ug-oxygen/ ... uclid.html

If you are using an older Author Component Project, your JNLP should contain additional references to the following libraries:

Code: Select all

        <jar href="lib/jeuclid-core.jar"/>

        <jar href="lib/batik-all-1.7.jar"/>

        <jar href="lib/commons-io-1.3.1.jar"/>

        <jar href="lib/commons-logging-1.1.1.jar"/>

        <jar href="lib/xmlgraphics-commons-1.5.jar"/>

You can take them from a standalone installation of Oxygen from the lib folder.
The extra JARs need to be signed along with the others.

Regards,
Radu

Thank you, Radu.
Another question: as i see, by default, neither Standalone Editor, neither Web Component does not resolve formulas from href links:

Code: Select all


<math type="presentation" href="../../mathml/numeric.mml" format="mathml"/>

Is it also possible?

Hi Yuri,

You could add to the CSS used to edit DITA content the selector:

Code: Select all

*[class~="math-d/math"][href]{

    content:attr(href, url);

}

But of course this would only present the image for editing.
For publishing you would need to make separate changes.

Radu
