Hi Armin: You reply said "Another way is to add a '.zip' to the AOO file name and to open it as archive". how to do it?
Can you give a simple and complete example, Programming languages using C++ ,runtime environment for Microsoft Windows. Look forward to your reply.

I have no idea, I never used something like this. If the example extension does it currently and it is allowed to save any binary data at the PNG then you can do the same (probably). To find out if it is saved with the file I would check if it is saved currently with the TexMaths extension. Another way is to add a '.zip' to the AOO file name and to open it as archive. There you can check for the contained single files and data, your binary data should be there somewhere. > The difference between them is > LaTeX equations is small and short, The new type picture is large. > can This method rigth? If it serves your needs and works it is right. You need to check if the files you create are loadable by a standard office (the AOO3.4 release version for example). It should load and show the PNG. I cannot say if it will strip your binary data when saving changed, you have to find out yourself. The only possible drawback is when you or other people using your extension would spread files generated this way and these files are very big. This may cause high eMail loads and similar effects. People may ask 'why is this file so big, there is only one picture in it'. I would suggest to not spread such files with extra data in them too much, maybe you only need to use them inhouse or privately anyways. It is a very specialized usage of ODF files. > The benefits of the treatment is: > do not have to program a import filter, > without considering the compatibility of the file , > Only insert a picture into openoffice's write.
