9.2.2 Basics of Showing Text
EXAMPLE 1
This example illustrates the most straightforward use of a font. The text ABC is placed 10 inches from the bottom of the page and 4 inches from the left edge, using 12-point Helvetica.

BT
    /F13 12 Tf
    288 720 Td
    (ABC) Tj
ET

The five lines of this example perform these steps:
a) Begin a text object.

b) Set the font and font size to use, installing them as parameters in the text state. In this case, the font resource identified by the name F13 specifies the font externally known as Helvetica.

c) Specify a starting position on the page, setting parameters in the text object.

d) Paint the glyphs for a string of characters at that position.

e) End the text object.
