I have an MS Word 2013 document containing mathematical formula which I want to transform into image, programmatically.
What I tried is:
Since Office 2007 Microsoft has changed representation of mathematical formulas into Office MathML (OMML) format.
- I could covert this formula in OMML format into MathML format. My Java code for the same:
//get xslt
StreamSource xlsStreamSource = new StreamSource("D:/TEMP/OMML2MML.XSL");
//Get the document.xml from .docx file
StreamSource xmlStreamSource = new StreamSource("D:/TEMP/word/document.xml");
//Using xalan transformer factory.
TransformerFactory transformerFactory = TransformerFactory.newInstance("org.apache.xalan.processor.TransformerFactoryImpl", null);
File pathToHTMLFile = new File("D:/TEMP/Newfolder/word/documentModified.xml");
StreamResult result = new StreamResult(pathToHTMLFile);
Transformer transformer = transformerFactory.newTransformer(xlsStreamSource);
transformer.transform(xmlStreamSource, result);
- Now I have "result" containing formula into MathML format. When I try to put this formula into Clipboard to get image flavor out of it, it is stored as plain XML text, there is no image flavor available.
//Writing and reading provided XMLstring into and from Clipboard
/**
* Write to Clipboard.
* @param s string containing MathML representation
* @param owner
*/
public static void writeToClipboard(String s, ClipboardOwner owner)
{
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
Transferable transferable = new StringSelection(s);
clipboard.setContents(transferable, owner);
}
/**
* Read clipboard data as image
* @return Image
* @throws Exception
*/
public static Image getImageFromClipboard() throws Exception
{
Transferable transferable = Toolkit.getDefaultToolkit().getSystemClipboard().getContents(null);
if (transferable != null&& transferable.isDataFlavorSupported(DataFlavor.imageFlavor)) {
return (Image) transferable.getTransferData(DataFlavor.imageFlavor);
} else {
return null;
}
}
I want to write MathML(XML) into clipboard, so i can read image flavor out of it. How can I write this MathML formula format into Clipboard, so I will get image flavor out of it?
Note:I am not sure whether I am going in right direction or not.If there is any existing API available for the same that would be more easier to do this.
