I'm creating a game and I'd like to use Java's Font.MONOSPACED font, because it is easy to use (even though it looks disgusting). The problem is that I have no idea about the fonts width-height-ratio, which is very important. I couldn't find a answer online after searching for a while.
If someone knows it or how to find it out, I'd be very grateful.
java.awt.FontMetrics is going to be your friend here.
You get access to it through a Graphics2d object:
Graphics2D gfx = ...;
gfx.setFont(...); // select your preferred font, monospaced or otherwise
FontMetrics metrics = gfx.getFontMetrics();
having done so you can get: (all from the above link to docs)
The width of any single char:
charWidth(char ch)Returns the advance width of the specified character in this Font.
The width of a string:
stringWidth(String str)Returns the total advance width for showing the specified String in this Font.
The height of a line
getHeight()Gets the standard height of a line of text in this font.
I assume you can figure out how to get a width-height ratio from the above, and you can get lots of other information from different FontMetrics methods - check it out.
