Enlarged it how?
As soon as you "scale" an image, rounding errors are introduced...
Take his source, maybe with a font 10 X bigger, and then using
imagecolorat to examine each pixel in the original, and see if it's
off...
And, really, if drawing text with a 1-pixel error margin throws you
off, you're in trouble anyway...
Though the super dark 90-degree text versus the others with much
larger variations in length is disconcerting, in your image, if those
length calculations are correct...
