Title: Drawed sfString too small
Post by: evilgoto on December 18, 2011, 06:08:13 pm

Hey,

I have a sfString with a size of 13px. I try to get the string's height via

Code: [Select]

string_h = rect.Bottom - rect.Top;
The result is - as the string's size - 13px.

Now, I draw the string via sfRenderWindow_DrawString() and take a screenshot of the running application; if I zoom in the screenshot via gimp, there is no char higher than 10px.

How can I get a string that is really 13px tall instead of 10px?

The character size (13 px) is the size of the tallest possible character. It doesn't mean that all your characters will be 13 px high. It wouldn't make sense ;)

Well, okay, sure. But is there any way to get the height of the tallest character in the string instead of the tallest possible?

Not directly. But if you use SFML 2, you can iterate on the glyphs (with sf::Font::GetGlyph) and compute the size yourself.
