Paste microsoft office equation object(old doc format) problem

[wolf1860]

I opened a doc file(97-2003 format) in Microsoft word 2016,copied a equation (ctrl+C), pasted(Ctrl+V) to TRichviewEdit(my version is 16.15.11),the result was that 2 same images displayed in the TRichviewEdit, No.1 is bigger than No.2 .
I created a new docx file ,inserted a new equation in word 2016,copied and pasted,the result is right.

thanks a lot!

I received your file, and analyzed RTF produced by MS Word when this document is copied to the Clipboard.

RTF often contains alternative representation of the same information.
In this file I can see:
1. OLE object Equation, with an alternative representation as a metafile. TRichView reads a metafile.
2. RTF field, containing RTF math object, with an alternative representation as an image, and image has two representations, as a PNG and a metafile. TRichView reads PNG.

So you can see two pictures, metafile and PNG.
But I cannot find any information in this file specifying that this OLE object and RTF field are alternative to each other, or that one of them must be hidden. Either MS Word has a special processing for RTF containing this type of OLE objects, or I do not understand something.


If I select an equation in MS Word and copy to another document, then copy this new document to TRichView, an image is inserted only once, because new RTF contains only OLE object, without RTF field.

The problem could be solved by non-reading picture representation of RTF math objects. BUT...
If I insert an equation in the new format, RTF file contains only a math object, without OLE object. So, if TRichView would ignore it, it could not be able to read new equations.

The only solution I can suggest is adding $ifdef for ignoring pictures in RTF math objects, so you will be able to import your old documents.

I used copy/paste function to import word document,can u give me some code to define $ifdef? By the way ,I opened the doc and select all (ctrl+a) and paste to a new document,the second image still exist,how should I do manual to avoid this problem? I can edit the original document freely.

thanks a lot!

I thought out it one more time and it seems now understand what to do.
The RTF math object and its alternative picture are placed in the "field instance" section. This is an unusual situation, normally, only field codes must be there. I changed the code to ignore pictures inside the field instance, and everything looks ok now, in all cases (your document, equation copied from your document, equation inserted in new version of Word)

This change will be included in the next update.
