I have a slideshow with text in front of each image. In some slides, the text is in front of a dark area, in others in front of a light area. I want to emphasize the text so it can be easily read in all slides.
In Illustrator, I would give the text a white fill and a black stroke, and increase the stroke until all text stands out. I understand that I can check “Outline” Format > Character > Font effects, but I cannot control the width of the stroke.
In Illustrator, I could also apply a feathering or halo effect around each letter, e.g. black letters and a white halo fading to 0% opacity. I don’t think I can do that in LibreOffice.
The only solution I found was to have a text box with a transparent color (Format > Object and shape > Area) and have text inside it. For example, black text works well with a white background of 50% transparency. One problem is that this wastes a good deal of the background image and the sharp edges of the partially opaque text box can fall on a face in the image.
Does LibreOffice have any other method of emphazing text on top of any image?
