Hi Armin: I send an Email to Texmaths's author , asked he some questions, communicate with each other as follows:
My question: LaTeX will equations can be inserted as images (SVG or PNG formats) and the LaTeX, code is saved into the image attribute for further editing. His reply: Image attributes are not stored directly in the png file but in LibreOffice data that are attached to the image. But he did not tell me how to attached the image in openOffice data,could you tell me?
