I'm looking for a specific font that's really bold and big. I see a ton of them and when I actually use them, the area inside the font that is white, turns out to be transparent when I type it out in a picture.

Is there something I can do to all these fonts like this or will I have just to search until I find one that's not transparent by luck. I can't tell from scrolling through, because they are all filled in with White just how I want it to look on the sample.

Example: SF SLAPSTICK COMIC SHADED under the comic section
