public DocOleObject appendOleObject(byte[] oleBytes, DocPicture olePicture, OleObjectType type) API how to use?
OleObjectType.Math_Type
I want to pass spire.Doc.5.2.3.jar inserts a mathematical equation into word in the Java environment,
and the mathematical equation can be edited by opening MathType through ole.
However, the API doesn't know how to use it.

Hello,

Thanks for your inquiry!

Please refer to the following article to insert math equations to the Word file : Java insert math equation to Word

If you want to get or edit the math equation which already exists, please refer to the following code to achieve this:

Code: Select all

        Document doc = new Document();
        doc.loadFromFile("data/GetMathEquation.docx");
        StringBuilder stringBuilder = new StringBuilder();
        for(int i=0;i<doc.getSections().getCount();i++){
            for(int j=0;j<doc.getSections().get(i).getParagraphs().getCount();j++){
                for(int k=0;k<doc.getSections().get(i).getParagraphs().get(j).getChildObjects().getCount();k++){
                    DocumentObject obj =doc.getSections().get(i).getParagraphs().get(j).getChildObjects().get(k);
                    if (obj instanceof OfficeMath) {
                        OfficeMath math=(OfficeMath)doc.getSections().get(i).getParagraphs().get(j).getChildObjects().get(k);
                        //get or edit as you wish
                        stringBuilder.append(math.toMathMLCode()+"\n");
                    }
                }
            }
        }

Thank you for your answer. The math equations of docx file can be modified manually through MathType, but it seems impossible.

Hello,

Thanks for your feedback!

You can refer to the following code to change the math equations:

Code: Select all

      String codeString = "<mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\" xmlns:m=\"http://schemas.openxmlformats.org/officeDocument/2006/math\"><mml:mn>2</mml:mn><mml:mi>α</mml:mi><mml:mo>-</mml:mo><mml:mi>s</mml:mi><mml:mi>i</mml:mi><mml:mi>n</mml:mi><mml:mi>y</mml:mi><mml:mo>+</mml:mo><mml:mi>x</mml:mi></mml:math>";

......
                  OfficeMath math = (OfficeMath) doc.getSections().get(i).getParagraphs().get(j).getChildObjects()
                        .get(k);
                  math.getChildObjects().clear();
                  math.fromMathMLCode(codeString);
......
