Draws formatted text, with word wrap and alignment.
See additional notes in love.graphics.print.
The word wrap limit is applied before any scaling, rotation, and other coordinate transformations. Therefore the amount of text per line stays constant given the same wrap limit, even if the scale arguments change.
In version 0.9.2 and earlier, wrapping was implemented by breaking up words by spaces and putting them back together to make sure things fit nicely within the limit provided. However, due to the way this is done, extra spaces between words would end up missing when printed on the screen, and some lines could overflow past the provided wrap limit. In version 0.10.0 and newer this is no longer the case.
In versions prior to 11.0, color and byte component values were within the range of 0 to 255 instead of 0 to 1.
|
Aligning does not work as one might expect! It doesn't align to the x/y coordinates given, but in a rectangle, where the limit is the width. |
|
|
Text may appear blurry if it's rendered at non-integer pixel locations. |

Notes
The color set by love.graphics.setColor will be combined (multiplied) with the colors of the text.
Examples
Draw text to the screen with right alignment and a horizontal limit of 125.
love.graphics.printf("This text is aligned right, and wraps when it gets too big.", 25, 25, 125, "right")
Notes
Note that the limit argument affects the position of your text for 'center' and 'right' alignment.
love.graphics.printf("This text is aligned center",100, 100, 200,"center") -- center your text around x = 200/2 + 100 = 200
love.graphics.printf("This text is aligned right",100, 100, 200,"right") -- align right to x = 100 + 200 = 300
