I have a long text in Text Area, which is too long to fit. As the app window and the text area is changing size (possibly also font size), the text is partially hidden. I'd like to know, how many lines of text are actually visible.

I'd take a vertical profile and threshold it. You forgot to attach your picture. But if you have an image with black text on a white background
verticalProfile = mean(grayImage, 2);
mask = verticalProfile < 128;
[labeledLines, numberOfLines] = bwlabel(mask)
