Hi,

I have a project in which I have to print reports containing mathematical formulas (with MathML syntax).
With my 2013 release of EO.PDF, it was fine, but with my recent update to the last release, formulas are not printed correctly in the PDF (but it's OK on screen preview with Firefox).
The code inside my html file is like this :
Code: HTML/ASPX
<td>
<math xmlns="http://www.w3.org/1998/Math/MathML">
<mstyle>
<mrow>
<mtable columnspacing="0.167em" columnalign="right center left" displaystyle="true">
<mrow><msub><mi>MB</mi><mn>F</mn></msub><mo>=</mo><mfrac><mrow><mrow><msub><mi>V</mi><mn>1</mn></msub></mrow><mo>-</mo><mi>V</mi><mo>ʹ</mo></mrow>
<mrow><mrow><msub><mi>M</mi><mn>1</mn></msub></mrow></mrow></mfrac>
<mo>.</mo><mn>1</mn><mn>0</mn></mrow>
</mtable></mrow></mstyle></math>
</td>

Is there something I can do to display my formulas correctly in my PDF ?

Thanks

Hi,

The latest version uses Chromium browser engine and MathML is not yet supported by the Chromium browser engine (as a result event Google Chrome browser can't display the above HTML properly). Support for MathML has been in development by the Chromium team though and is expected to be released next year. Once that becomes available we will update our browser engine and support this feature. In the mean time, you can use JavaScript solution such as this one:

Please feel free to let us know if you have any more questions.

Thanks!
