I have a quick question:

How can I get the current textleading? I know I can set it with textleading(), but I want to get the current value, or somehow count it out (I guess it is connected to font size, just don't know how).

Thanks

Hi Psysoul,

From the processing sources, it seems that the leading is a float value which is equal to 14 by default (while font size default is 12). Whenever you change the font size the leading is set automatically by the formula:

   textLeading = (textAscent() + textDescent()) * 1.275f;

You can also access this value using g.textLeading (g being the reference to PApplet's PGraphics object).
For example,

Copy code

println(g.textLeading);
PFont font = createFont("Arial", 28);
textFont(font);
println(g.textLeading);

Thanks a lot, this works.

I wanted to get processings library source code to check this, but I could only find the processing application. Is there a way to check out the source code of the library source?

I browse the svn repo online while at work as i can't install a svn client.
I think what you want is to look at the "core" folder.
