在Writer貼入向量圖片為GDI中介檔，儲存檔案後會另存一份點陣圖

最近發現原來的odt檔案，使用LO 6.0.1 開啟後在儲存，檔案會變大。
嘗試後7zip開啟odt檔案檢視Pictures，發現原來的svm都另存一份png點陣圖。
專家設定中，我找不到可以關閉的選項，有人可以指導一下嗎？

請問這是什麼考量？是為了與docx轉檔的相容性嗎？

我嘗試使用7zip刪除所有的png，使用cmd下的命令列轉檔odt為docx，
在docx內，所有的svm轉檔為emf，似乎與docx轉檔的相容性無關。

如果可能，希望不要將svm另存一份png，徒增檔案的大小。

Including different representations of the same content is explicitly allowed in file format for this purpose. I cannot confirm your observation about Apache OpenOffice. I have got version 4.1.5 and it includes png-images too. And Word 365, which has an usable ODF export, includes a png-image as well. I do not know any setting to suppress incl…
