textAlign()
Sets the way text is aligned when text() is called.
By default, calling text('hi', 10, 20) places the bottom-left corner of the text's bounding box at (10, 20).
The first parameter, horizAlign, changes the way text() interprets x-coordinates. By default, the x-coordinate sets the left edge of the bounding box. textAlign() accepts
the following values for horizAlign: LEFT, CENTER, or RIGHT.
The second parameter, vertAlign, is optional. It changes the way text() interprets y-coordinates. By default, the
y-coordinate sets the bottom edge of the bounding box. textAlign() accepts the following values for vertAlign: TOP, BOTTOM, CENTER, or BASELINE.
Examples

function setup()
size(100, 100)
background(200)
-- Draw a vertical line.
strokeWeight(0.5)
line(50, 0, 50, 100)
-- Top line.
textSize(16)
textAlign(RIGHT)
text('ABCD', 50, 30)
-- Middle line.
textAlign(CENTER)
text('EFGH', 50, 50)
-- Bottom line.
textAlign(LEFT)
text('IJKL', 50, 70)
describe('The letters ABCD displayed at top-left, EFGH at center, and IJKL at bottom-right. A vertical line divides the canvas in half.')
end

function setup()
size(100, 100)
background(200)
strokeWeight(0.5)
-- First line.
line(0, 12, width, 12)
textAlign(CENTER, TOP)
text('TOP', 50, 12)
-- Second line.
line(0, 37, width, 37)
textAlign(CENTER, CENTER)
text('CENTER', 50, 37)
-- Third line.
line(0, 62, width, 62)
textAlign(CENTER, BASELINE)
text('BASELINE', 50, 62)
-- Fourth line.
line(0, 97, width, 97)
textAlign(CENTER, BOTTOM)
text('BOTTOM', 50, 97)
describe('The words "TOP", "CENTER", "BASELINE", and "BOTTOM" each drawn relative to a horizontal line. Their positions demonstrate different vertical alignments.')
end
