Text placement bug ... err.. feature :-}

Post by An00biS »

Hello.

I believe I've found a bug in LOVE's printf function - it behaves differently on Linux and Windows.

Here's the testing code:

Code: Select all

function love.draw()
   love.graphics.setColor(255,255,255,255);
   love.graphics.setLineStyle("rough");
   love.graphics.line(0,200,600,200)
   love.graphics.line(200,0,200,400)
   love.graphics.line(400,0,400,400)
   love.graphics.printf("X200 Y200 L200 center",200,200,200,"center");
end
Here's result on Windows XP, SP3:
text-pos-windowsXP.gif
text-pos-windowsXP.gif (3.66 KiB) Viewed 4492 times
Here's result on Fedora 13:
text-pos-Fedora13.gif
text-pos-Fedora13.gif (3.57 KiB) Viewed 4492 times
Does anybody here have the same problem?

I think you're using different versions -- starting 0.7, text is drawn top-left rather than bottom-left. You're using the PPA or something? my 666th post in S&D!

Are you using exactly the same versions in windows and ubuntu?

I think I've read somewhere that the Ubuntu version using on the PPA had been updated, or something along those lines. On the new version, the text placement is corrected so it uses top-left coordinates, like everything else.

EDIT- woops, got ninja'ed by robin.
When I write def I mean function.

Sometimes I wish I could draw text with the origin being the baseline. That is the bottom of the letters not counting the dangly parts. It could be useful in some situations. Does text have a way to retrieve the pixel height of the current font?

Well, 0.6.2 had baseline drawing, and current hg (not svn, mind you!) has top-left, you observed well.

If we could specify it optionally that would be neat. Can we in 0.7.0?

Unless I'm missing something, you can add textheight to the y coordinate instead of having an additional method.

Code: Select all

 love.graphics.print(x,y+height,text) 
vs

Code: Select all

 love.graphics.setTextBaseline(true)
love.graphics.print(x,y,text)

Yuck. Do it either manually, as your first example, or add an extra parameter to love.graphics.print(), I'd say (the former has my preference, btw).
