Wrapped text - length?
May 29th, 2009, 10:13pm  
Hello,

I'm using text(stringdata, x, y, width, height) and have been trying to work out how to tell if the text is longer than the width & height available. Whether all the text is visible or not.

I tried calculating using textAscent, textDescent, a count of new lines and the size of the box but that doesn't work because the wrap happens at words.  I also couldn't see how to find the default leading - textLeading() is for setting the leading, not getting it.

Is there an easier way than calculating the text line by line?

thanks,

Brenda

Great question.  There's no easy way to do this built into Processing.  If you develop a custom method for doing this and decided to share it, lots of other people (like me) would benefit.

Processing gives you textWidth(), but that isn't useful for blocks of text (i.e. more than one line).  As far as I know, there's not an easier way (yet).  Good luck!

Oh, and I think the default leading is just whatever point size you've specified, as in textFont(fontName, 24), so the leading would be 24 unless specified otherwise.
