ADE 4 - MathML expressions

1 Attachment(s)

Theorically, ADE 4 supports MathML but I couldn't get the following expression (after epub3 conversion) displayed:

Code:

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

<mrow>

        <msub>

                <mi>a</mi>

                <mn>1</mn>

        </msub>

        <mo>+</mo>

        <msub>

                <mi>a</mi>

                <mn>2</mn>

        </msub>

        <mo>+</mo>

        <mo>&ctdot;</mo>

        <mo>+</mo>

        <msub>

                <mi>a</mi>

                <mi>n</mi>

        </msub>

        <mo>=</mo>

        <mstyle displaystyle="true">

                <munderover>

                        <mo>&sum;</mo>

                        <mrow>

                                <mi>i</mi>

                                <mo>=</mo>

                                <mn>1</mn>

                        </mrow>

                        <mi>n</mi>

                </munderover>

        </mstyle>

        <msub>

                <mi>a</mi>

                <mi>i</mi>

        </msub>

</mrow>

</math>

And should look as:

Attachment 134152

Anyone can get that result?
Regards

PS: I have IE11 (I say that because ADE 4 won't render epub3 with IE10 or lower).

Apparently, the ADE 4 Windows version doesn't support MathML. If you want to test MathML, you can use the Readium Chrome plugin, which displays your formula fine. (Readium is the official IDPF ePub3 test app.)

Many thanks Doitsu. That means that ADE 4.0 for Windows is a washout :( I knew the formula was fine because under Gitden Reader (for Android) and even EpubReader for Firefox I could see the expression as expected but I couldn't get the same result with ADE. Now I know it was because ADE 4.0 -for Windows- DOESN'T SUPPORT MATHML. So, ADE 4 is to epub3 what ADE 3/2 is to epub2 :( (at least, under Windows)

It is clear that ADE 4.0 is tied to Internet Explorer code and IE is known to be really slow at support HTML5 so I would expect that until IE supports MathML you will not see it in ADE 4 and a whole lot of other things will not work.

According to http://html5test.com/compare/browser/ie-TP.html the beta version of IE will support MathML so there is a chance for a future point release of ADE 4. That web site, by the way, is a great place to see how browsers compare on HTML5 issues. You will see that even with the beta version IE is way behind most every other browser.

Thanks Dale. Now I'm trying to see if I can get math expressions on ADE by using scripts (again, theorically ADE should support scripts). I'm doing experiments with Mathjax and Katex but so far, no success :( :)

ADE 4.0.3 for Windows

According to the Adobe release notes ADE 4.0.3 for Windows supports MathML. However, I have been testing epub readers and so far I have found only Apple iBooks epub reader, Readium app for Chrome epub3 reader, and Calibre displays MathML correctly. I have also tried to display my MathML test equations in FireFox, IE, Chrome, and Safari browsers and found that only Firefox (38.0.1) displays the MathML equations correctly. The other three browser do not display MathML.

Here is my test epub that I have been using to test ePub readers. It containing two MathML equations, area of a circle and the quadratic formula:

Hope this helps.

Your test book also displayed OK with Gitden Reader; it didn't display OK with ADE 4, which was to be expected since your test book is an epub2 ebook and MathML support was introduced in epub3.
(After conversion to an epub3 ebook with the Sigil ePub3 plugin your test book displayed OK with ADE 4.)

The only problem you might have with MathML is people using older versions of ADE/RMDSK and MathML not properly displaying.

Thanks for your reply. I did change my test file to EPUB3 and it did work in ADE 4.0.3. I also downloaded Gitden Reader to my iPad and it too rendered my test file.

I have been using Azardi 38 Reader. So far it seems to render MathML equations the best. InfoGridPacific has created and old classic book (The theory of Heat Radiation - Dr. Max Plank) filled with both inline and block MathML statements that looks like a great test bed for MathML. I reviewed the book on Azardi 38 and Gitden Readers. The Gitden reader does not properly render parentheses and brackets. I also note that the ADE rendering of equations in my lastest MathML Tester depends on the setting of the font size in ADE. The only font size that render correctly is Extra Large. The other sizes mess up some aspect of one or more equations. Both the Azardi and Gitden readers render test file correctly.
