How to remove black boudaries around images globally?

[YuruiHong]

Recently I’m using Libreoffice to deal with some rather poor-configured documents where formula are inserted as inline images. It seemed that the black boudaries were displayed even in the printed pdf. I’ve tried multiple suggestions but none of them worked for me, and the only possible way to remove these boundaries up to now is by selecting the image → click “Draw” tab that emerged on the top → switch off “line”. But it’s awfully ineffficient as I have to do this for every image. Is it possible to remove the boundaries globally?

Attach an example file showing the effect and the actual nature of the objects you call “images”.

You didn’t attach a representative sample file:

• it is DOCX while document in your screenshot is .odt
• view settings are not the same: when I open the sample, all formatting hints are enabled while none is on the screenshot

Consequently, I can’t evaluate the similarities between both and can’t recommend a cure. Basically I suspect some setting in Formula frame style.

In addition, you configure your GUI for some dreaded ribbon interface which prevents feedback indications in the toolbar about your formatting. I fear that your document is completely direct formatted as is unfortunately encouraged by such a UI, which creates a mess.

I don’t understand what you’ve done because I get an Object tab, not a Draw tab when I click on a formula. Please, attach a reduced version of the document shown in the screenshot.
