MathML

Hi there!!

MathML for InDesign is great!!

I wish I could change font color something like below...

 

            <math mathcolor="#000000">
                <mrow>            
                    <mi>a</mi>            
                    <mi>b</mi>
                    <mi>c</mi>
                    <mi>d</mi>
                    <mi>e</mi>
                    <mi>f</mi>
                    <mi mathcolor="#d0111b">g</mi>
                    <mi>h</mi>
                    <mi>i</mi>        
                </mrow>            
            </math>

I can swear the question was for "font" - not "color"? 

 


They asked "change fonts for MathML, like color?" Meaning, I guess, "change font attributes, like colour".

By the way, has Adobe exposed any interfaces in the latest C++ SDK for handling mathematical expressions—specifically, for iterating through mathematical expressions within a text stream and retrieving their MathML string representations?

There's something I don't understand. @jimmy_2799 wrote 

 

>To change the font color in MathML for InDesign, you can use the mathcolor attribute as you've done in your example. This should apply the specified color to the elements within the tag.

 

That's what you did originally. He didn't say anything about mrow, which you applied, and which you claim worked. But when I tried it InDesign said that the structure is invalid (after inserting / in the closing <mrow> tag). Can you give us a screenshot that shows that it worked?

    @Peter Kahrel 

     

    You are right - but color change works without <mrow>:

    It does indeed when I tried again. No idea what went wrong earlier.

     

    But now I understand even less. @潔38992292yczw reported an MML structure which he said doesn't work, but which is in fact correct and works. Then he reports that he fixed it, but the fix is ungrammatical and doesn't work. Oh, well.

    As far as I'm aware it's SVG - so you'd need to export it from InDesign - manipulate it and replace it - or manipulate it after exporting for InDesign.

     

    SVG is RGB only and can't do 100% black in CMYK - -it's RGB black
